Foveal microvasculature features observed by optical coherence tomography angiography (OCTA) for closed macular hole (MH). a The OCTA image of the superficial capillary plexus (SCP) for a 40-year-old woman with the fellow eye; the foveal avascular zone (FAZ) is delineated by the white line with an area of 0.51 mm². b The OCTA image of SCP for the closed-MH eye; the FAZ area is 0.24 mm², which is smaller than that for the fellow eye. c The OCTA image of deep capillary plexus (DCP) for the fellow eye; the FAZ area is 0.56 mm². d The OCTA image of DCP for the closed-MH eye; the FAZ area is 0.26 mm², which is smaller than that for the fellow eye
