Nucleic acid vectors encoding light-gated cation-selective membrane channels, in particular channelrhodopsin-2 (Chop2), converted inner retinal neurons to photosensitive cells in photoreceptor-degenerated retina in an animal model. Such treatment restored visual perception and various aspects of vision. A method of restoring light sensitivity to a retina of a subject suffering from vision loss due to photoreceptor degeneration, as in retinitis pigmentosa or macular degeneration, is provided. The method comprises delivering to the subject by intravitreal or subretinal injection, the above nucleic acid vector which comprises an open reading frame encoding a rhodopsin, to which is operatively linked a promoter and transcriptional regulatory sequences, so that the nucleic acid is expressed in inner retinal neurons. These cells, normally light-insensitive, are converted to a light-sensitive state and transmit visual information to the brain, compensating for the loss, and leading to restoration of various visual capabilities.

A laser system that includes a diode pump source. A frequency doubled solid state visible laser is pumped by the diode pump source and produces a pulsed laser output with a train of pulses. Resources provide instructions for the creation of the pulsed output, with on and off times that provide for substantial confinement of thermal effects at a target site. This laser system results in tissue specific photoactivation (or TSP) without photocoagulation damage to any of the adjacent tissues and without causing full thickness retinal damage and the associated vision loss.

A method and apparatus for providing microcurrent stimulation (MSC) therapy. In accordance with the present invention, it has been determined that the application of microcurrent signals at particular frequencies to the eye for particular periods of time stabilizes and even improves conditions of macular degeneration and other ocular diseases. Experimental data from clinical trials shows that results of persons who underwent therapy are at least better than placebo, and that the therapy is safe and efficacious. In fact, experimental data from clinical trials showed that approximately 98% of the patients who underwent the MCS therapy of the invention experienced either stabilization or improvement of macular degeneration within one year of starting therapy. Of this percentage, approximately 65% of the patients subjected to the MCS therapy experienced improved vision, while approximately 32% experienced stabilization of macular degeneration (i.e., no further loss of vision).

A visual defect simulation system receives a functional field map produced by an MRI system that relates locations in a patient's brain to locations in the patient's field of view. Planned medical operations are indicated at locations in the patient's brain and any resulting vision loss is simulated with a revised functional field map. A scene is displayed and an impairment overlay is produced from the revised functional field map that blocks the scene at locations corresponding to simulated vision loss. The overlay is translated over the scene in response to viewer eye movements detected by a vision-tracking system to present a real-time simulation of the resulting vision loss.

A nutritional or dietary supplement composition that promotes retinal health through the prevention and / or treatment of visual acuity loss by reducing the risk of developing age-related macular degeneration in persons with early age-related macular degeneration.

The composition is taken in the form of one or two tablets or capsules daily.

A visual distortion test is disclosed using a sequence of binary interactions with a mobile device, in which segments of the grid having no distortions are eliminated, and the segments with distortions are divided into smaller segments for further analysis. The test can quantify the visual distortion using a decreased number of steps, compared to sequential analysis of all the segments of the grid. The binary interaction or input to the mobile device is also easier for patients than graphic interactions with a conventional Amsler Grid. Early detection of changes in the visual distortion can enable the healthcare provider to individualize treatment, helping to prevent vision loss while minimizing visits to the office, discomfort, and expense.

The present invention provides a reading test to measure vision loss. In one embodiment, the vision loss is due to disease progression. The tests are useful in evaluating the effects of intervention in vision deterioration. The tests are non-invasive, simple, quick, sensitive, reproducible, and easy to administer. The tests measure the subject's reading speed and accuracy under defined conditions of illumination and contrast. The results of these tests may be used to determine if treatment of a disease should be initiated, terminated, altered, or remain unchanged.

Novel vision monitoring and diagnostic testing tools and help-seeking enablers that may be used individually or in combination as vision monitoring and diagnostic testing systems that improve patients' ability to recognize onset and progression of visual changes over time, so that the identification of acute or chronic visual conditions may be improved and accelerated, which drives earlier help-seeking behavior by the patient, which enables earlier clinical diagnosis by an eye care specialist and therefore earlier treatment and therefore reduced likelihood of severe vision loss.

A method of at-home monitoring of eye conditions using a head mounted display that is capable of establishing a visual model associated with a patient. The visual model may include data related to a quality of the patient's vision. The patient may use the system to establish a visual model periodically, such as daily, and the system may compare the visual model to previous visual models and send an alert to the patient's physician if changes meeting a given criteria are detected. This may allow the physician to immediately take steps to save the patient's eyesight where a delay in treatment may result in vision loss.
