Geometric perfusion deficit (GPD) is a newly described OCT angiography (OCTA) parameter identifying the total area of presumed retinal ischemia. The aim our study to characterize differences in GPD and other common quantitative OCTA parameters between macular full field, perivenular zones, periarteriolar zones for each clinical stage nonproliferative diabetic retinopathy (DR) assess influence ultrahigh-speed acquisition averaging on differences.
