Development and evaluation of Order of Magnitude (OM): a virtual reality-based visual field analyzer for glaucoma detection.

Purpose: This study introduces the Order of Magnitude (OM), a cost-effective, indigenous, virtual reality-based visual field analyzer designed for detecting glaucomatous visual field loss.

Methods: The OM test employs a two-step supra-thresholding algorithm utilizing stimuli of 0.43°diameter (equivalent to Goldmann size III) at low and high thresholds.

Agreement Between Virtual Reality Perimetry and Static Automated Perimetry in Various Neuro-Ophthalmological Conditions: A Pilot Study.

Our objective was to compare the agreement between virtual reality perimetry (VRP) (order of magnitude, OM) and static automated perimetry (SAP) in various neuro-ophthalmological conditions. We carried out a retrospective analysis of visual field plots of patients with various neuro-ophthalmological conditions who underwent visual field testing using VRP and SAP and between 1 January and 31 May 2022. Two fellowship-trained neuro-ophthalmologists compared the visual field defects observed on both devices.
