Age and gender influence on foveal avascular zone in healthy eyes.

The foveal avascular zone (FAZ) is the capillary-free area in the central macula with high photoreceptor density and metabolic activity. In the present study we measured the superficial and deep macular foveal avascular zone (sFAZ, dFAZ) in the eyes of healthy adults of both sexes of various ages ranging from 10 to 69 years using optical coherence tomography angiography (OCT-A) in order to evaluate the influence of gender and age on FAZ size. A cross-sectional study was carried out in 240 eyes of 120 healthy subjects, OCT-A was performed by means of a Topcon swept source OCT.
