7 results about "Visual acuity loss" patented technology

Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing symmetric or asymmetric optic with aspheric surface which redirects and / or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The intraocular lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the intraocular lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the intraocular lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles.

Certain embodiments disclosed herein include projecting an azimuthal grid into a patient's eye. A computer system projects the azimuthal grid into the patient's eye while taking one or more images of the patient's retina, for example, using SLO. A fixation grid may also be displayed, and the patient is instructed to gaze at a fixation target. The computer system overlays the azimuthal grid onto one or more images to obtain one or more output images. One or more output images are displayed to at least one of the surgeon and / or the patient. The surgeon and / or the patient may examine the output images and use the coordinates of the azimuthal grid to communicate the location of a floating object.

Disclosed herein are methods, devices, and systems for monitoring fluid outflow behavior of an eye of a subject, for example, during ocular surgery. Changes to intraocular pressure can reflect fluid outflow behavior. Fluid outflow behavior can be a critical factor in the successful outcome of a surgery and determining likelihood of post-operative side effects. Large fluctuations in intraocular pressure, ocular hypertension, and hypotony can be associated with vision loss or poor ocular health.

Disclosed is a method of treating a patient with Geographic Atrophy or with wet Age-related Macular Degeneration or Choroidal Neovascularization. Also disclosed is a method of delaying the progression of vision loss in a patient with Geographic Atrophy or with wet Age-related Macular Degeneration or Choroidal Neovascularization. The methods comprise administering an effective amount of gildeuretinol acetate to the patient.

Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing a piggyback lens which in combination with the cornea and an existing lens in the patient's eye redirects and / or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The piggyback lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the piggyback lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the piggyback lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles.

Disclosed herein are cells, cellular compositons, methods, and systems for restoring vision loss in a patient suffering from same. In many embodiments, the disclosed cells may be retinal ganglion cells (RGCs) expressing one or more survival-enhancing factors, for example small heat shock protein Bl, HSPB 1, which may be driven by an RGC-specific promoter. In many embodiments, expression of the survival-enchancing factor may allow RGCs transplanted into the patient's retina to more effectively repopulate the RGC population.

The system according to this embodiment aims to provide early detection and countermeasures for vision loss and visual impairment. [Solution] The system according to the embodiment comprises a collection unit, an analysis unit, a detection unit, a notification unit, and a suggestion unit. The collection unit collects visual acuity test data, eye photographs, and lifestyle data. The analysis unit analyzes the data collected by the collection unit to understand the individual's visual state. The detection unit detects abnormalities based on the data analyzed by the analysis unit. The notification unit notifies the abnormalities detected by the detection unit in real time. The suggestion unit proposes preventive measures and corrective measures based on the abnormalities detected by the detection unit.
