Design outcomes

Primary

MeasureTime frame
1. To determine the sensitivity and specificity of the FDT and 24-2 SITA strategies on the virtual reality headset in comparison to SAP. 2. To assess the correlation of visual field findings between the FDT and 24-2 ZEST strategies on the virtual reality headset and the HFA in varying severity of glaucoma.Timepoint: 6 months—

Secondary

MeasureTime frame
To compare average time per eye for virtual reality headset testing with SAP Patient preferences in performing virtual reality headset testing vs. SAPTimepoint: 6 months—
