Trial Summary

What is the purpose of this trial?

This proof-of-concept study aims to determine the feasibility and effectiveness of using a custom head-mounted device for visual field testing. The novel head-mounted device, with custom software, will be compared to a conventional visual field test: The Humphrey Visual Field Analyzer. The investigators will include 30 healthy normal patients, 30 glaucoma suspects, 30 patients with moderate glaucoma, and 30 patients with advanced glaucoma (total: 120 patients). Each patient will perform the conventional test and the head-mounted device visual field test during the study visit, with the order (i.e., which device the patient starts with) being randomized. After the two tests, the patient will fill out a questionnaire to gather information regarding patient comfort and satisfaction. This will repeat each week for 5 weeks, for a total of 5 study visits. The results of the tests (sensitivity thresholds) will be compared. The investigators hypothesize that the results of the conventional and head-mounted device will be similar.
