FAZ area clearly decreasing in the eye of a 59-year-old male, 6 months after receiving conbercept treatment. Notes: OCT angiography images (a–c) depict macular ischemia and apparent FAZ expansion captured in 6 × 6 mm2 sections in the macular area at month 0, Q-score = 8/10. a FAZ area with 0.604 mm2, showing severe FAZ area expansion and arch ring capillary network breakage; b Superficial capillary plexus (ILM-IPL), vessel density of 39.2%; c Deep capillary plexus (IPL-OPL), vessel density of 43.5%;. At month 6, OCT angiography images (a’–c’) showed FAZ area decrease, Q-score = 9/10. a’ FAZ area with 0.464 mm2; b Superficial capillary plexus vessel density of 40.4%; c Deep capillary plexus vessel density of 43.1%
