Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Previous visual field test with Humphrey Field Analyzer indicating normal field, early glaucomatous field damage, or advanced glaucomatous field damage, according to Canadian Glaucoma Society Guidelines.
* Ability to understand and consent to the study.

Exclusion Criteria

* Presence of non-glaucomatous pathology that could influence the visual field test, such as media opacities.
* Previous intraocular surgery less than 6 months from inclusion.
* Difficulty to execute a reliable visual field test.
* Potential contra-indications to use of virtual reality headset, including: anxiety disorder, pregnancy, seizure disorder, cardiac pacemaker or other implantable device, severe vertigo or balance disturbance.
