What this Trial Is About
Perimetry is an essential component in the diagnosis and monitoring of glaucoma. Since the advent of Standard Automated Perimetry (SAP), one of the clinical standards has been the Humphrey Field Analyzer (HFA, Carl Zeiss AG, Oberkochen, Germany). Visual field (VF) testing provided by the HFA is standard-of-care in glaucoma clinics and other ophthalmology and optometry practices. However, the HFA is a large device that does not allow for examination outside the clinic and can be uncomfortable for patients with limited mobility. This study aims to evaluate a novel head-mounted perimeter against the HFA as an alternative method of VF testing. This new perimeter uses a Virtual Reality (VR) headset and a gamified version of VF testing to assess the visual function of healthy eyes and patients. The results of this study will potentially serve as pilot data for the design of a larger study that involves the full assessment of the VR headset and its VF test, based on various testing strategies.
