Images of a case showing CC pattern of gradually increasing flow signals after PDT. ICGA (a) of baseline reveals partial choriocapillary hyperpermeability (red arrow) and focal hypo-fluorescent areas (blue arrow). 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. Dilatation of CC (red arrow) accompanied by dark areas (blue arrow) can be seen at baseline (b). Recovery sign of increasing flow signals and decreasing dark areas was found at 1 week (c) after half-dose PDT and at the following 1-m (d), 3-m and 6-m (e) follow-ups, while foci of dark areas (blue arrows) remained
