Virtual Reality for Enhancement of Vision

Not Applicable
Terminated
Conditions
Glaucoma
Vision Disorder
Registration Number
NCT07071129
Lead Sponsor
Stanford University
Brief Summary

This project aims to evaluate the use of Virtual Reality (VR) based visual stimulation for the treatment of blindness arising from Glaucoma and other retinal diseases or disorders of the visual system, through regeneration of axons of retinal ganglion cells (RGCs) in humans.

In certain cases of blindness, such as in Glaucoma, or in certain injuries, the optic nerves behind the retina of our eyes get damaged, leading to partial blindness, mostly near the periphery of our eye. Recent research in Dr.Huberman's laboratory has identified visual stimulation as a non-invasive model for regeneration of such damaged axons in rodents, back to the vision centers of their brain.

Primary Outcome Measures
NameTimeMethod
Change in Mean Deviation Index (MD)baseline and 2 years

MD is a global measure of the visual field. It is a statistical index that represents the average difference in visual field sensitivity compared to a normal age-matched population. It provides an overall measure of visual field loss in decibels, with more negative values indicating greater loss.

Change in Visual Field Index (VFI)baseline and 2 years

VFI (expressed as a percentage) is a global measure of the visual field used to quantify the extent of visual field loss, with 100% representing a normal visual field and 0% indicating complete blindness.

Secondary Outcome Measures
NameTimeMethod
Change in Retinal Layer Thickness assessed by Optical Coherence Tomography (OCT)baseline and 2 years

OCT is a non-invasive imaging technique that uses light waves to create detailed, cross-sectional images of the eye, and is used to diagnose and manage various eye conditions.
