Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Perimetry (or visual field testing) is a vision test used to evaluate a patient's peripheral vision. It involves a patient fixating on a central target and pressing a button when they see a spot of light in their peripheral vision. It is an important way of deciding whether Glaucoma is progressing or not. Next generation virtual reality (VR) technologies offer an exciting new way of conducting perimetry in either a clinical or home environment, allowing more affordable and more frequent monitoring of disease progression in glaucoma, and an easier and more comfortable experience for patients. The investigators propose to create a perimetry test using a commercially available head mounted display for VR, and to assess its accuracy in glaucoma patients in relation to standard automated perimetry.

Visual field testing using Oculus Rift and Humphrey Visual Field Perimeter

Glaucoma patients at Queen's University, Belfast, will be invited to undergo both Visual field testing using the Oculus Rift and the gold-standard Humphrey 24-2 (Carl Zeiss Meditec, Dublin, CA) at two visits, and evaluating consistency for detecting visual field impairments.

Intervention Type DEVICE

Visual Field Testing using HUmphrey 24-3 Perimeter

Glaucoma patients at Queen's University, Belfast, will be invited to undergo both Visual field testing using the Oculus Rift and the gold-standard Humphrey 24-2 (Carl Zeiss Meditec, Dublin, CA) at two visits, and evaluating consistency for detecting visual field impairments.

Eligibility Criteria

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

Inclusion Criteria

\- Patients with a clinical diagnosis of glaucoma with repeatable defects on standard automated perimetry.

Exclusion Criteria

* Presence of other ocular disease which impacts vision such as age-related macular degeneration or diabetic retinopathy.
* Any physical limitation that would make the participant unable to place their head in the head-rest to perform Humphrey Perimetry (Eg some patients with arthritic or neck problems are unable to use the headrests of ophthalmic devices).
* Any cognitive impairment that would limit their ability to perform perimetry or a history of vertigo/dizziness.
