Rao HL, et al. - The diagnostic abilities of peripapillary optical microangiography (OMAG) measurements in eyes with primary open-angle glaucoma (POAG) were assessed herein. Researchers also gauged the association of these measurements with retinal nerve fiber layer (RNFL) thickness and visual sensitivities in different peripapillary sectors. The best diagnostic ability in glaucoma was demonstrated by the inferior sector OMAG measurements, which also showed the strongest relationship with RNFL and the visual sensitivity measurements. However, the diagnostic ability of OMAG measurements was significantly less than the RNFL thickness measurements.
