Optic coherence tomographic angiogram of the macular area and optic nerve from a 22-year-old male. (a) Foveal avascular zone (the area within the inner annulus). (b) Foveal area (the area within the inner circles) comprising the parafoveal area (the annulus between the inner and middle circles) and perifoveal area (the annulus between the middle and outer circles). The diameter of inner, middle, and outer circles is 1.0 mm, 3.0 mm, and 5.0 mm, respectively. (c) Peripapillary (the annulus between the inner and outer circles).
