Purpose: Clinically evaluate the noninferiority of a custom virtual reality (VR) perimetry system when compared to clinically and routinely used perimeter on both healthy subjects glaucoma patients. Methods:We use custom-designed VR tailored for visual field testing.The uses Oculus Quest headset (Facebook Technologies, LLC, Bern, Switzerland), that includes clicker participant response feedback.A prospective, single center, study was conducted at Department Ophthalmology Bern University Hospital (Bern, Switzerland) 12 months.Of 114 participants recruited 70 (36 34 patients with early moderate loss) were included in study.Participants underwent tests an Octopus 900 (Haag-Streit, Köniz, as well perimeter.In cases, standard dynamic strategy (DS) conjunction G testing pattern.Collected fields (VFs) from devices then analyzed compared.Results: High mean defect (MD) correlations between two systems (Spearman, ρ ≥ 0.75) obtained.The found slightly underestimate VF defects (1.4 dB).No significant bias respect eccentricity or subject age.On average, similar number stimuli presentations per necessary measuring subjects. Conclusions:This demonstrates proposed have comparable performances parameters loss.Translational Relevance: This suggests perimeters potential assess VFs high enough confidence, whereby alleviating challenges current practices by providing portable more accessible test.
