Images of a case showing CC pattern of transient network of neovascularization. ICGA (a) of baseline revealed widespread lesions of choriocapillary hyperpermeability (red arrow) with hypo-fluorescent areas within them. En-face OCTA (b-e) of CC slab and the corresponding cross-sectional B-scan OCT (b-e) demonstrated the CC flow changes with time. Local dialed CC patterns in macular region surrounded by defused flow signal void were noticeable at baseline (b). An emerging network of neovascularization (green arrow) accompanying foci of reduced flow signals (blue arrow) was observed at 1 week after half-dose PDT (c), which gradually subsided (green arrows) during subsequent follow-ups of 1 month (d), 3 months and 6 months (e) while focally recovering with CC perfusion (blue arrow)
