About

This study aim to determine the feasibility of using a virtual reality (VR) headset (HTC Vive) to test the visual field. The VR headset test will be compared to a conventional visual field test, using the Humphrey Field Analyzer. The investigators will include 10 healthy patients without visual field defect, 10 patients with early glaucomatous visual field defect, and 10 patients with advanced visual field defect. Each patient will perform the conventional test twice and the VR headset test 4 times, divided in 3 visits within a 2 month period. The results of the tests (sensitivity thresholds) will be compared. The investigators hypothesize that the results of the conventional and VR tests will be similar.
