This prospective, single-center study evaluates the inter-test comparability between the Humphrey Visual Field Analyzer (HFA) and the RVF 100 (VR) perimeter device developed by RetinaLogik Inc. A total of 20 eyes from 12 patients (70% glaucoma-suspect, 30% glaucoma patients) were tested using both devices on the same visual field grids (24-2 or 30-2).
Key visual field metrics—mean deviation (MD), pattern standard deviation (PSD), global mean sensitivity (MS), and pointwise sensitivity—were analyzed using linear regression and Bland-Altman plots. Results showed strong correlations across all parameters, with Pearson coefficients exceeding 0.80 (p<0.0001). Pointwise comparisons revealed a mean light sensitivity difference of 1.02 dB across locations.
The study concludes that the VR headset shows high agreement with HFA results, supporting its potential as an accessible, portable alternative for routine glaucoma care and visual field assessment.
