WEARABLE COMPREHENSIVE EYE EXAMINATION DEVICECROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to U.S. Provisional Patent Application Serial No. 63 / 645,788 filed May 10, 2024 titled WEARABLE COMPREHENSIVE EYE EXAMINATION DEVICE, the entire disclosure of which is incorporated by reference herein.BACKGROUND

[0002] Vision loss is a growing healthcare problem globally with an estimated 1 .8 billion people experiencing vision loss by 2050, rapidly diminishing quality of life and stripping away a person's independence. This is a big problem not only for the one going blind but also for their family members and loved ones. The cost of blindness in the world was a staggering $410 billion in 2023, highlighting the significant financial implications of visual impairments. Most cases of blindness can be prevented through early detection and intervention, but the current state of eye examination technology and accessibility is not sufficient to address this problem. As the population aged 65 and over grows to 22% by 2050, and rates of obesity and subsequently diabetes rise to nearly 40%, the blindness problem will only continue to get bigger. Currently, less than half of those at risk attend their regular check-ups due to lack of access to eye screening and care which is needed for early detection blindness prevention. For many, traveling to a clinic for an exam relatively frequently is either not possible or highly impractical. Moreover, the healthcare sector faces additional challenges due to decreasing reimbursements, necessitating the care for more patients with dwindling resources. To address these challenges a shift in how eye examination and care is provided is required.

[0003] Traditional exam techniques, such as slit lamp and binocular indirect ophthalmoscope (BIO), involve large, cumbersome, centralized equipment and require a patient’s physical presence which limits the reach providers have in the care of patients. These devices, despite being the gold standard for eye care, are bulky, difficult to use,and depend on ancillary support like various lenses and assistants to complete a comprehensive eye exam.

[0004] In addition, those traditional-based techniques and equipment do not preserve high quality stereopsis level digital recording of the examination, linking records to electronic patient records which makes doctors, and their staff do additional work by typing, drawing, and / or using other large and bulky equipment for photography.

[0005] Furthermore, current examination devices only show the eye for a short time, and they don't give patients a record of their complete examination. This makes it harder for patients to understand their eye health issues and / or leads to duplicated work when patients need to see a specialist or get another opinion.

[0006] Therefore, and as the healthcare landscape evolves, there is a pressing need for innovative solutions that enable high-quality eye care outside traditional settings, making it accessible and convenient for patients regardless of their mobility or location and digitizing eye examinations. This shift towards integrating technology and telemedicine into eye care is essential for addressing the growing demand and financial strain on the healthcare system.SUMMARY

[0049] Housed within the cavity 122 of the main body 102, as shown in FIG. 3, is the examination module 110. In accordance with some aspects disclosed and contemplated herein, the examination module 110 may comprise a plurality of components operable to effectuate a series, sequence, or individual steps to conduct an eye examination, as discussed in greater detail below. The examination module 110 is illustrated more fully in FIGS. 4A-10B. As shown in FIG. 4A-10B, the examination module 110 comprises a housing 111 formed of any suitable material, e.g., polymer, metal, metal-alloy, or a suitable combination thereof. The housing 111 of the examination module 110 may define an interior cavity 115 in which one or more components of the examination module110 are positioned. The housing 111 may further comprise a top surface 113 and an exterior surface 117, the exterior surface 117 corresponding to a surface of the housing111 that faces the patient, e.g., a surface of the housing 111 positioned opposite the surface proximal to the display screen 118 as shown in FIGS. 4A-4B. The examination module 110 may comprise an anterior illumination module (AIM) 126 positioned on a top surface 113 of the housing 111 , a posterior illumination module (PIM) 128 located withina cavity 115 defined by the housing 111 , an orbital socket observation module (OSM) 130 positioned on an exterior (i.e., patient-facing) surface 117 of the housing 111 , a posterior illumination kinematic mirror 132 located within the cavity 115 of the housing 111 , a stereopsis imaging module (SIM) 134 located within the cavity 115 of the housing 111 , and an objective lens 136 position on the exterior surface 117 of the housing 111.

[0050] As shown in FIGS. 4A-10B, with particular reference to FIGS. 5-6B, the examination module 110 is further mounted to a 2-axis motion stage 138 responsible for translating the examination module 110 vertically along a first axis and proximal-distal relative to the patient’s face along a second axis. The 2-axis motion stage 138 is itself mounted to another single axis motion stage 140 which operates to translate the examination module 110 laterally along a third axis. The assembly of the 2-axis motion stage 138 and 1 -axis motion stage 140 provides overall 3-axis motion control to the examination module 110. While shown in FIGS. 5-6B as being screw driven, it will be appreciated that the 1 -axis motion stage 140 may be implemented as gear-driven, belt drive, pulley-drive, magnetic drive, hydraulic drive, pneumatic drive, or the like.

[0051] In accordance with some embodiments disclosed and contemplated herein, the motion of the examination module 110 inside the main body 102 results from controlled actuation of motor-gearbox assemblies 146 and 152 for the 2-axis motion stage 138 and screw-drive 150 for the 1 -axis motion stage 140. The electric motors of the motor-gearbox assemblies 146, 152, and 148 may be implemented as stepper motors, DC motors, or the like. The motion slides 144 and 142 of the 2-axis motion stage 138 are drive by the aforementioned screw-drive 150 like shown for the 1 -axis motion stage 140, or as noted above, via belt-drive, pulley, hydraulic, pneumatic, etc. Operations of the 2-axis motion stage 138 and / or the 1 -axis motion stage 140 may be controlled via operations of the controller 400, as described in greater detail below with respect to FIG. 12.

[0052] In accordance with some example embodiments disclosed and contemplated herein, the examination module 110 may be configured to conduct an anterior eye examination. For example and without limitation, an eye examination of the cornea and iris, via operation of the anterior illumination module 126 wherein an LED light source 154 is mounted to an articulating surface 156 with adjustable vertical slits 158 and horizontal slits 160. FIGS. 7A-9B provide illustrative views of the examination module 110configured for anterior and / or posterior eye examination operations in such an example embodiment. The illumination module 126 is contained within an illumination module housing 162 which itself contains at least one illumination lens 164. The illumination module 126 is mounted to an illumination module base 166. A 1 -axis motion stage 168 causes for lateral translation of the articulating surface 156 under power from an electric motor preferably a stepper motor but alternatively a DC motor.

[0053] Continuing with the example operations discussed with respect to FIGS. 7A- 7B, the anterior illumination module (AIM) 126 may be configured to adjust the direction of light being emitted by the LED light source 154 such that it projects onto the anatomy of the anterior eye e.g., cornea or iris, in a manner dictated by the caregiver, e.g., doctor, nurse, technician, etc.. In some embodiments of the present disclosure, the positioning of the anterior illumination module 126 to achieve the desired illumination of the eye anterior is achieved via direct input by the caregiver with real time visual feedback to guide the positioning of the anterior lighting. In accordance with various embodiments disclosed and contemplated herein, the positioning of the anterior illumination module 126 occurs automatically without direct input from the caregiver and instead utilizes control algorithms to position the lighting to enable inspection of a desired eye anatomy or disease condition. It will be appreciated that the anterior eye examination module 126 may be configured to perform an anterior eye examination including but not limited to inspection of the cornea, pupil, iris, and angle anatomy.

[0054] As illustrated in FIGS. 4A-10B, the examination module 110 also includes an orbital socket observation module 130 positioned on a surface 117 (i.e., patient-facing) of the examination module housing 111. In some embodiments disclosed and contemplated herein, the orbital socket observation module 130 may be configured to guide the motion of the examination module 110 as anterior and / or posterior examinations are being conducted. In further embodiments, the orbital socket observation module 130 may be operable to inspect the condition of the sclera, eyelids, and / or surrounding tissues.

[0055] Continuing with the examination module 110, FIGS. 7A-9B provide an illustrative example with respect to the various components thereof operable to capturing images of the anterior eye in accordance with some embodiments disclosed and contemplated herein. As shown in FIGS. 7A-9B, the stereopsis imaging module (SIM)134 operates to capture live stream images of the anterior eye including but not limited to the cornea 200, pupil 202, and iris 204. The SIM comprises a relay lens 170, a proximal beam splitter prism 172, a distal beam splitter prism 174, and a pair of imaging camera modules 176 with an imaging lens 210 positioned in front of each camera. This collectively comprises the imaging path and is used during anterior eye examination and posterior eye examination, albeit in the ladder case the objective lens 136 must also be included in the imaging path. The imaging camera module 176 further comprises a lens package 188 and CMOS sensor 190. The CMOS sensor 190 in a preferred embodiment is flat but alternatively can be curved whereas the curvature of the CMOS sensor 190 provides means to address optical aberration as the curvature can be used to reduce or eliminate the need for additional lenses along the imaging path to correct for the aforementioned optical aberrations, thereby simplifying the construction of the imaging path and enabling the examination module 110 to be small and compact. The illumination and imaging optical paths are indicated via simple ray traces shown in FIG. 8B.

[0056] In accordance with some embodiments, depending on the examination needs, and level of stereopsis quality needed, use of one or two sensors may be required. Within the example architecture of the examination module 110 shown in FIGS. 8A-9B, one or both sensors could be activated but even with just one sensor activated the examination may be carried out and provide sufficient information. Accordingly, the performance of stereopsis imaging utilizes the dual sensors of the stereopsis imaging module 134, as will appreciated the sensors are available as an imager, regardless of whether the dual sensor enabled stereopsis imaging module 134 is active or not.

[0057] With continuing reference to FIGS. 8A-9B, the relay lens 170 in accordance with some embodiments, may comprise a traditional spheric lens or alternatively a single aspheric, double aspheric lens, gradient index lenses (GRIN), or geometrically flat meta lens. In embodiments utilizing a meta lens for the relay lens 170, the optical track length of the imaging path may be shortened as the thickness of a meta lens can be substantially less when compared to a traditional lens performing the same function. Accordingly, it will be appreciated that the use of a meta lens as the relay lens 170 may provide space saving considerations with respect to the fitment of the examination module 110 within the main body 102 of the wearable eye-examination device 100.

[0058] Referring particularly to FIGS. 9A-9B, the examination module 110, as briefly discussed above, may further comprise a posterior illumination module (PIM) 128 comprising a pair of vertical slits 182 and horizontal slits 184 positioned in front of the retina illumination LED 186. In accordance with some embodiments, the vertical slits 182 and horizontal slits 184 may be adjustable, as dictated by the caregiver, or alternatively by automated control algorithms via the controller 400 (as discussed in greater detail below with respect to FIG. 12). In such embodiments, adjustments to the vertical slits 182 and / or the horizontal slits 184 may control the shape of light emitted the retina illumination LED 186 permitted to be inserted into the imaging path. As will be appreciated, light emitted from the retina illumination LED 186 may reflect off the retina illumination kinematic mirror 132 and be directed toward the objective lens 136. The retina illumination kinematic mirror 132 preferably is a mirror with a hole 208 through its center to allow the retina image to pass through and enter the stereopsis imaging module 134. According to some embodiments, the posterior illumination module 128 may be configured to conduct a posterior examination including but not limited to inspection of the retina posterior pole including optic nerve and macula, equatorial retina, peripheral retina, and vitreous body.

[0059] As shown in FIGS. 8A-9B, when the wearable eye-examination device 100 is configured to conduct posterior examination, e.g., set to posterior examination mode, the objective lens 136 may be positioned in line with the imaging path, and accordingly may be moved to be in line with the imaging path via 1 -axis objective lens translation slide 212 powered by a motor actuator 214, and be moved out of the imaging path when the eye examination device 110 is configured to conduct an anterior examination. The light from the retina illumination LED 186 after reflecting off the retina illumination kinematic mirror 132 is focused down by the objective lens 136 to and furthermore by the cornea 200 before passing through the pupil 202 of the patient’s iris 204. This light, which is augmented by the selected state of the vertical slits 182 and horizontal slits 184 then diverges after traversing the plane of the iris 204 to illuminate a predetermined area of the retina 206.

[0060] The light reflected from the retina 206 exits the pupil 202 and cornea 200 and the objective lens 136 and creates an image of the retina 206 which is redirected by therelay lens 170 before entering the proximal beam splitter prism 172 and distal beam splitter prism 174. As the image rays pass along the beam splitter prisms, they are reflected into imaging cameras 176. Each imaging camera 176 images an area (e.g., a portion) of the retina 206 whereas the specific area (e.g., portion) imaged by each camera 176 covers nearly the same area but with a predetermined offset to achieve a stereopsis effect when the images collected by one imaging camera 176 are merged with the images collected by the second imaging camera 176. As will be appreciated, such a configuration mimics the way in which human eyes achieve stereopsis and thus is a bioinspired digital imaging solution.

[0061] Continuing with FIGS. 8A-9B, it will be appreciated that the angle at which each imaging camera module 176 is placed may be manipulated so as to adjust the angle of perspective each camera module 176 has viewing the retina image and furthermore to assist in segregating image rays that are intended to enter the entrance pupil 188 of each camera module 176. As shown in FIGS. 8A-9B, the configuration of the posterior illumination module (PIM) 128 utilizes the segregation of image rays as one method of achieving stereopsis.

[0062] In accordance with some embodiments disclosed and contemplated herein, the angle referenced above may be greater than or equal to 1° and less than or equal to 20° inclusive angle offset between one imaging camera module 176 and the other camera module 176. In other embodiments, the angle is greater than or equal to 10and less than or equal to 19°, greater than or equal to 1° and less than or equal to 18°, greater than or equal to 10and less than or equal to 17°, greater than or equal to 10and less than or equal to 16°, greater than or equal to 1 ° and less than or equal to 15°, greater than or equal to 10and less than or equal to 14°, greater than or equal to 10and less than or equal to 13°, greater than or equal to 1° and less than or equal to 12°, greater than or equal to 1° and less than or equal to 12°, greater than or equal to 1° and less than or equal to 11°, greater than or equal to 10and less than or equal to 10°, greater than or equal to 10and less than or equal to 9°, greater than or equal to 1 ° and less than or equal to 8°, greater than or equal to 1 ° and less than or equal to 7°, greater than or equal to 1° and less than or equal to 6°, greater than or equal to 1° and less than or equal to 5°, greater than or equal to 1° and less than or equal to 4°, greater than or equal to 1° and less than or equal to 3°,greater than or equal to 1° and less than or equal to 2°, greater than or equal to 2° and less than or equal to 20°, greater than or equal to 3° and less than or equal to 20°, greater than or equal to 4° and less than or equal to 20°, greater than or equal to 5° and less than or equal to 20°, greater than or equal to 6° and less than or equal to 20°, greater than or equal to 7° and less than or equal to 20°, greater than or equal to 8° and less than or equal to 20°, greater than or equal to 9° and less than or equal to 20°, greater than or equal to 10° and less than or equal to 20°, greater than or equal to 11° and less than or equal to 20°, greater than or equal to 12° and less than or equal to 20°, greater than or equal to 13° and less than or equal to 20°, greater than or equal to 14° and less than or equal to 20°, greater than or equal to 15° and less than or equal to 20°, greater than or equal to 16° and less than or equal to 20°, greater than or equal to 17° and less than or equal to 20°, greater than or equal to 18° and less than or equal to 20°, greater than or equal to 19° and less than or equal to 20°, or any ranges therein.

[0063] Referring now to FIGS. 10A-10B, there are shown internal views of the wearable eye-examination device 100 in accordance with some embodiments disclosed herein. As depicted in FIGS. 10A-10B, the wearable eye-examination device may further comprise an internal display 118, and a main electronics board 216 (which may include an internal controller 400, described below with respect to FIG. 12). The wearable eyeexamination device 100 may further include one or more power sources, e.g., batteries 127A, 127B positioned within the wearable eye-examination device 100 and configured to provide electrical power to the various components, e.g., the controller 400, display 118, speakers (not shown), (gears / motors e.g., 140-152), and the like. In accordance with some embodiments, the batteries 127A, 127B may be implemented integrally mounted or replaceable. In some embodiments, such batteries 127A, 127B may be rechargeable including, for example and without limitation, lithium-ion batteries, nickelcadmium batteries or the like. In other embodiments, replaceable alkaline, lithium, etc., batteries may be used. In other embodiments, an external power supply (not shown) may be used to supply electrical power to the aforementioned components of the wearable eye-examination device 100. In still further embodiments, a combination of internal and external power supplies (e.g., internal batteries, USB or proprietary connected externalpower source) may be used to provide electrical power to one or more of the aforementioned components.

[0064] As illustrated in FIGS. 10A-10B, one or more driver boards 218 e.g., an array of such boards, may be internally mounted to the wearable eye-examination device 100. In some embodiments, the one or more driver boards 218 may be communicatively and / or operatively coupled to one or more respective motors, actuators, etc. (e.g., the aforementioned components) used throughout the wearable eye-examination device 100 and control and / or provide power for such components. According to some exemplary embodiments disclosed and contemplated herein, the power supply(ies) (e.g., the batteries 127A, 127B), the main control board 216 (e.g., including the controller 400), the one or more driver boards 218, etc., may be configured to operate in conjunction with each other (or individually) to perform a variety of operations including, for example and without limitation, conducting eye examinations, acquiring digital images as stills or video, communicating with one or more external devices (e.g., a server, display, tablet, or other suitable personal communications device).

[0065] As previously noted, the wearable eye-examination device 100 may further comprise a display screen 118 mounted within the main body 102 proximal to the screen shield 104 and viewable through the face pad 106. According to some embodiments, the display screen 118 may be visible to both patient eyes (dependent upon positioning of the examination module 110) and may be partially activated in accordance with the eye opposite the eye being examined by the examination module 110. In varying embodiments, the display screen 118 may be implemented as an LCD screen, an LED screen, a projection-based screen, or any suitable screen as will be appreciated. As will be appreciated, this configuration of the wearable eye-examination device 100 may allow for the patient to direct their gaze, as the eye not being examined can observe visual targets displayed on the display screen 118, to aid in conducting a comprehensive eye exam. For example, fixation targets 220, as depicted in FIG. 10B, may be displayed on the display screen 118 in front of the patient’s eye not being examined by the examination imaging module 110 to direct the patient’s gaze to bring different portions of the anterior or posterior anatomy into view.

[0066] In accordance with some embodiments, the wearable eye-examination device 100 discussed above with respect to FIGS. 1A-10B may be utilized in a distributed eyeexamination system 300. FIGS. 1 1A-1 1 B depicts such a system 300 for performing comprehensive eye examinations utilizing one or more wearable eye-examination devices 100 in accordance with some example embodiments disclosed and contemplated herein. It will be appreciated that the system 300 depicted in FIGS. 1 1 A-1 1 B is intended solely as one non-limiting example implementation using the wearable eye-examination device 100 described herein, and other implementations are contemplated herein. It will be appreciated that the various components depicted in FIGURES 1 1 A-1 1 B are for purposes of illustrating aspects of the exemplary embodiment, and that other similar components, implemented via hardware, software, or a combination thereof, are capable of being substituted therein.

[0067] As shown in FIGURES 1 1 A-11 B, the system 300 includes a central system 301 represented generally as the server 302, which is capable of implementing the exemplary method described below. The exemplary server 302 includes a processor 304, which performs the exemplary method by execution of processing instructions 306 that are stored in memory 308 connected to the processor 304, as well as controlling the overall operation of the server 302.

[0068] The instructions 306 may include a caregiver identification component 310 configured to identify a particular caregiver, e.g., a doctor, clinician, technician, nurse, physician’s assistant, optometrist, ophthalmologist, etc., associated with the operation of a particular wearable eye-examination device 100. In some embodiments, the caregiver identification component 310 may be configured to identify a particular caregiver device 500 in communication with a particular wearable eye-examination device 100 and / or associated with a particular caregiver. According to various embodiments disclosed and contemplated herein, the caregiver identification component 310 may be configured to receive caregiver identification information 328 from a caregiver device 500 including, for example and without limitation, name, position, location, device ID (e.g., MAC, IP, or other address associated with the caregiver device 500), wearable eye-examination device ID (e.g., MAC, IP, or other address associated with a particular wearable eye-examination device 100 assigned or otherwise associated with a particular caregiver), and the like.

[0069] The instructions 306 stored in memory 308 may further include a patient identification component 312 configured to identify a particular patient, e.g., name, DOB, medical history, vitals, etc., associated with an eye examination being conducted or to be conducted using the wearable eye-examination device 100 in accordance with the systems and methods described herein. In some embodiments, the patient identification component 312 may retrieve patient information 326, e.g., the aforementioned name, DOB, medical history, vitals, etc., based upon communications received by the server 302 via the caregiver device 500.

[0070] As shown in FIGS. 11 A-11 B, the instructions 306 may also comprise a wearable eye-examination device identification component 314 configured to identify a particular wearable eye-examination device 100. In some embodiments, the wearable eye-examination device identification component 314 may utilize wearable eyeexamination device information 332 (e.g., MAC address, IP address, serial number, or other identifying indicia) to identify a particular wearable eye-examination device 100 being utilized in accordance with the systems and methods described herein. According to some embodiments, the identification performed by the eye-examination identification component 314 may be used to determine the status of a particular device 100, a caregiver associated with a particular device 100, a location of the device 100, or the like. Other uses of the identification performed by the wearable eye-examination device identification component 314 may be appreciated and are contemplated herein.

[0071] The instructions 306 stored in memory 308 may further include an artificial intelligence component 316. In some embodiments, the artificial intelligence component 316 may be implemented as an artificial neural network, which may be composed of an interconnected group of artificial neurons (e.g., neuron models), is a computational device or represents a method performed by a computational device. These neural networks may be used for various applications and / or devices, such as Internet Protocol (IP) cameras, Internet of Things (loT) devices, autonomous vehicles, and / or service robots.

[0072] Individual nodes in the artificial neural network may emulate biological neurons by taking input data and performing simple operations on the data. The results of the simple operations performed on the input data are selectively passed on to other neurons. Weight values are associated with each vector and node in the network, and these valuesconstrain how input data is related to output data. For example, the input data of each node may be multiplied by a corresponding weight value, and the products may be summed. The sum of the products may be adjusted by an optional bias, and an activation function may be applied to the result, yielding the node's output signal or “output activation.” The weight values may initially be determined by an iterative flow of training data through the network (e.g., weight values are established during a training phase in which the network learns how to identify particular classes by their typical input data characteristics).

[0073] Different types of artificial neural networks exist, such as recurrent neural networks (RNNs), multilayer perceptron (MLP) neural networks, convolutional neural networks (CNNs), and the like. RNNs work on the principle of saving the output of a layer and feeding this output back to the input to help in predicting an outcome of the layer. In MLP neural networks, data may be fed into an input layer, and one or more hidden layers provide levels of abstraction to the data. Predictions may then be made on an output layer based on the abstracted data. MLPs may be particularly suitable for classification prediction problems where inputs are assigned a class or label. Convolutional neural networks (CNNs) are a type of feed-forward artificial neural network. Convolutional neural networks may include collections of artificial neurons that each have a receptive field (e.g., a spatially localized region of an input space) and that collectively tile an input space. Convolutional neural networks have numerous applications. In particular, CNNs have broadly been used in the area of pattern recognition and classification.

[0074] In layered neural network architectures, the output of a first layer of artificial neurons becomes an input to a second layer of artificial neurons, the output of a second layer of artificial neurons becomes an input to a third layer of artificial neurons, and so on. Convolutional neural networks may be trained to recognize a hierarchy of features. Computation in convolutional neural network architectures may be distributed over a population of processing nodes, which may be configured in one or more computational chains. These multi-layered architectures may be trained one layer at a time and may be fine-tuned using back propagation. Accordingly, the artificial intelligence component 316 may be instantiated as any of the foregoing.

[0075] In some embodiments, the artificial intelligence component 316 may be trained using data including, for example and without limitation, images 356 with corresponding diagnoses 352, medical images (e.g., medical databases, etc.), and the like. In other embodiments, the artificial intelligence component 316 may learn particular examination routines 354, so as to automatically select a particular routine 354 associated with a patient, a caregiver, a particular wearable eye-examination device 100, a particular caregiver device 500, or the like. Accordingly, the trained artificial intelligence component 316 may, in conjunction with one or more of the other components of the server 302 described herein, analyze images 356 to identify a diagnosis 352 associated with a particular eye examination.

[0076] In some such embodiments, the aforementioned examination routines 358 may be derived via the artificial intelligence component 316 as indicated above. In other embodiments, such examination routines 358 may be defined directly by a caregiver input, wherein a particular caregiver assists in training the artificial intelligence component 316 to utilize the caregiver’s particular examination routine 358. Thus, embodiments of the subject disclosure may provide caregivers with the ability to create, automatically run / enable, etc., a custom examination routine 358. As shown in FIG. 1 , such a custom examination routine 358 may be added to the examination routines 358 stored in the data storage 344 and thereby made accessible for adoption and / or usage by other caregivers. For example, a particular technique implemented by a custom examination routine 358 created by “Doctor Smith”, may be stored in the data storage as the “Doctor Smith Technique”, and be accessible by other caregivers desiring to implement the “Doctor Smith Technique.”

[0077] As illustrated in FIGS. 11 A-11 B, the instructions 306 may also comprise an image processing component 318 configured to analyze one or more images 356 received from a wearable eye-examination device 100 in accordance with some embodiments disclosed and contemplated herein. In accordance with some embodiments, the image processing component 318 may be configured to process the images 356 so as to extract medical information therefrom. In such embodiments, the image processing component 318 may interact with the artificial intelligence component 316 so as to identify the medical information from the images 356.

[0078] The instructions 306 stored in memory 308 may further comprise a diagnosis component 320 configured to assist in the and / or perform diagnoses of images 356 received from a wearable eye-examination device 100. In accordance with some embodiments, the diagnosis component 320 may be in communication with the data store 344, accessing the diagnoses 352 stored therein to assist in ascertaining a diagnosis associated with a particular image 356 of a patient’s eye. Such a diagnosis may be made in accordance with an output of the image processing component 318, via the artificial intelligence component 316 via computer vision, image analysis, via communication with the caregiver device 500 (e.g., doctor’s analysis of images 356, and the like), etc.

[0079] The instructions 306 may further include a communications component 322 configured to establish a secure communication link between a wearable eyeexamination device 100, a caregiver device 500, and / or the server 302. In accordance with some embodiments, the communications component 322 may be configured to establish a secure communications link between the wearable eye-examination device 100, the caregiver device 500, and the server 302. Suitable secure communications links may utilize one or more encryption schemes, algorithms, protocols, etc., protecting the communication of data between the various devices 100, 500, 302. In some embodiments, the encryption and security measures implemented by the communications component 322 may adhere to, meet, or exceed requirements established for compliance with health care data, e.g., HIPAA, etc.

[0080] In accordance with some embodiments, the communications component 322 may be configured to host a caregiver and / or a patient portal, e.g., a website, app, or the like, operable to provide updates, images, guidance, facilitate bi-directional communication between the caregiver and the patient, or the like. In other embodiments, the communications component 322 may be configured to dynamically communicate instructions / controls received from the caregiver device 500 to the wearable eyeexamination device 100 during an eye examination. Accordingly, via such bi-directional communications, a caregiver device 500 may view images 356 (e.g., static and / or video) in real-time, alter modes of the wearable eye-examination device 100, focus or move cameras, and the like.

[0081] The various components of the server 302 associated with the central system301 may all be connected by a data / control bus 338. The processor 304 of the server302 is in communication with an associated data storage 344 via a link 346. A suitable communications link 346 may include, for example, the public switched telephone network, an Internet connection, a proprietary communications network, infrared, optical, or other suitable wired or wireless data communications. The data storage 344 is capable of implementation on components of the server 302, e.g., stored in local memory 308, i.e., on hard drives, virtual drives, or the like, or on remote memory accessible to the computer system 302. Various components depicted in the data storage 344 may also be accessible by the server 302 via third party service providers, e.g., AMAZON, MICROSOFT, GOOGLE, proprietary databases, and the like,

[0082] Accordingly, it will be appreciated that in some embodiments, the associated data storage 344 corresponds to any organized collections of data used for one or more purposes. Implementation of the associated data storage 344 may occur on any mass storage device(s), for example, magnetic storage drives, a hard disk drive, optical storage devices, flash memory devices, or a suitable combination thereof. The associated data storage 344 may be implemented as a component of the server 302, e.g., resident in memory 308, hosted by third parties, or the like.

[0084] The server 302 may include one or more input / output (I / O) interface devices 334 and 336 for communicating with external devices. The I / O interface 334 may communicate, via communications link 348, with one or more of a display device 340, for displaying information, such estimated destinations, and a user input device 342, such asa keyboard or touch or writable screen, for inputting text, and / or a cursor control device, such as mouse, trackball, or the like, for communicating user input information and command selections to the processor 304.

[0085] It will be appreciated that the system 300 is capable of implementation using a distributed computing environment, such as a computer network, which is representative of any distributed communications system capable of enabling the exchange of data between two or more electronic devices. It will be further appreciated that such a computer network includes, for example and without limitation, a virtual local area network, a wide area network, a personal area network, a local area network, the Internet, an intranet, or any suitable combination thereof. Accordingly, such a computer network comprises physical layers and transport layers, as illustrated by various conventional data transport mechanisms, such as, for example and without limitation, Token-Ring, Ethernet, or other wireless or wire-based data communication mechanisms.
