Impact of Anatomically Defined Retinal Zones on Ultrawide-Field Fluorescein Angiography Nonperfusion Measurements in Diabetic Retinopathy
While the diameter of the retinal measurement zones did not differ significantly, the location of the zone center had a substantial impact on NPI measurements. Using FA-defined zones centered on the optic disk led to lower mid-peripheral and higher far peripheral NPI measurements, providing a more accurate prediction of progression to PDR compared to fovea-centered zone.
