Feasibility, Accuracy, and Reproducibility of Virtual Reality Visual Field Testing in Patients With Glaucoma

This study tests whether a virtual reality (VR) headset can accurately and reliably measure visual field defects in people with glaucoma — a condition that damages the nerve connecting the eye to the brain — potentially offering a more accessible alternative to traditional clinic-based vision field testing. **You may be eligible if...** - You are over 18 years old - You have been diagnosed with primary open-angle glaucoma - You are able to perform visual field testing - You are able to consent to participate in research **You may NOT be eligible if...** - You have secondary glaucoma or a different type of optic nerve disease - You have had previous eye surgery (other than cataract surgery or minimally invasive glaucoma procedures) - You have significant lens clouding that could affect test results - You are pregnant, have a seizure disorder, have a cardiac pacemaker or implantable device, or have severe dizziness or balance problems Talk to your doctor to see if this trial is right for you.
