Problems solved by technology

With tens of millions of additional AMD patients expected to age in the near future, there is an urgent need to increase capacity and efficiency as we see inefficiencies in traditional eye exams and a shortage of eye care providers (ophthalmologists and optometrists)

example 1

[0082] As noted above, an eye care professional using our system remotely can typically effectively evaluate a retinal photo and make a gestural swipe or click diagnosis in less than ten seconds, especially for normal photos. Significantly unusual photos may also take less than 10 seconds to quickly tag with a swipe or tap, and then quickly categorize them again with a swipe or tap. These correspond to the first and second layers described above. If an eye care professional can average one (or a left and right pair) retinal assessment every 10 seconds, that translates to 6 patients / pair of eyes per minute and 360 per hour. Assuming two hours of rest and six hours of active work per day and assessments five days per week, it is conceivable that each eye care specialist could assess 10,800 patients per week, or approximately 540,000 patients per year, at a cost of only A fraction of traditional inspections. A busy eye care professional may perform traditional eye exams on 50 p...

example 2

[0084] Busy eye care professionals don't need to spend their entire day with our systems. Instead, a few hours per day were enough to make a significant difference—both patient-to-patient and off-hours. If each ophthalmologist analyzes retinal photographs for 2 hours per week (720), that is 3,600 per week, and 3 hours per weekend (1,080), or 2,160 per weekend, the total number of patients evaluated per year per ophthalmologist is 288,000 .

[0085] In another embodiment, after images pass a quality control image check (see eye imaging camera description) and are uploaded and transmitted, diagnostic algorithms aid in the diagnosis of diabetic and hypertensive retinopathy and annotate specific retinal features suggestive of diagnosis. Initially, we first used AI to classify images of healthy retinas as a preprocessing step before human readers. This is logical, since healthy eyes show less variation in appearance; therefore, AI can diagnose "healthy" more accurately. As we bu...

Abstract

A new ocular contact lens has been designed to increase the amount of light reaching the retina. The contact lens edge is chamfered to redirect and increase the light reaching the retina. A light source encircles and contacts the straight or curved chamfered edge. Additionally, a reflective cylinder and its top wall encircle the lens to block any loss of light. This distal edge of the contact lends may be rounded to increase the angle of retina visible. A new ocular imaging camera has a low-light camera subassembly with server, a photosensor next to low-light camera, a short cylindrical housing, a space between the camera subassembly and the housing, an internal program in server to detect good or poor image quality and an alarm for poor image quality, wherein an operator recaptures the image.

Description

technical field [0001] Embodiments of the illuminated contact lens assembly relate to lens assemblies for use with eye imaging cameras. Particular embodiments also include reflectors and light sources to illuminate the anterior and posterior segments of the patient's eye. These devices are used in rapid diagnostic systems. Background technique [0002] Visual impairment can lead to the loss of the ability to read, operate a computer, walk, socialize and operate a vehicle, thereby affecting their ability to survive and their quality of life. Ophthalmologists typically diagnose the cause of blindness after primary health care practitioners refer patients complaining of vision problems and loss of function (eg, difficulty reading or driving). Worldwide, the World Health Organization reports that the most common cause of blindness is cataracts, followed by age-related macular degeneration and diabetic retinopathy. Most severe vision loss occurs in people over the age of 50. ...
