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

Conditions studied

Glaucoma Open-Angle

About this study

The goal of this clinical trial is to evaluate the feasibility of using virtual reality based visual field testing to monitor glaucoma in a clinical setting. This will be done through comparison of a virtual reality (VR) based device to the current gold standard Ziess Humphrey Field Analyzer (HFA). The main questions the study aims to answer are: * Can both devices produce similar results in terms of detecting visual field defects and progression? * Does the stage (early, moderate, advanced) of glaucoma impact results between the two devices? Participants will perform both a standard and a VR based visual field test at each visit, for a total of 5 visits.

Interventions

• Device: Virtual Reality Visual Field (VR-VF) — Both devices administer a standard visual field test. The Humphrey is the gold standard desk top model and the VR-VF is a virtual reality headset designed to deliver visual field testing

Primary outcomes

• Visual field point-wise threshold values (Measured during each visual field test on visits 1 through 5 (throughout study completion, average 2 months))
• Global indices of visual field loss (Measured during each visual field test on visits 1 through 5 (throughout study completion, average 2 months))
• Reliability Indices (Measured during each visual field test on visits 1 through 5 (throughout study completion, average 2 months))
