Electrical Stimulation for the Treatment of Optic Neuropathies

This study is testing whether a non-invasive electrical stimulation device applied near the eye can slow or improve vision loss in people with glaucoma-related optic nerve damage. Participants use the device at home to receive gentle electrical pulses that may help preserve or stimulate remaining nerve function. **You may be eligible if...** - You are 18 or older with a confirmed diagnosis of glaucoma - You have measurable vision field loss (mean deviation worse than -3 on standard testing) - Your eye pressure is considered stable by your doctor **You may NOT be eligible if...** - You have a history of eye herpes infection - You have a pacemaker or other implanted electrical device - You have significant retinal disease (like diabetic retinopathy or retinitis pigmentosa) - You have corneal opacities, uveitis, or active eye inflammation - You have a brain tumor or incompatible metal implants in the head - You are pregnant or breastfeeding - You have dementia or another condition that would interfere with participation Talk to your doctor to see if this trial is right for you.
