Images of a case showing CC pattern of worse CC ischemia followed by persistent type I CNV. ICGA (a) of baseline revealed multifocal choriocapillary hyperpermeability (red arrows). 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. Defused dilatation of CC (red arrow) (b) can be detected at baseline, with punctate dark areas within the lesions. Local worse CC ischemia (blue arrows) was found at 1 week after half-dose PDT (c), combined with dynamic changes of neovascularization of sprouts (d) at 1-m follow-up, and grew with loose network of CNV (green arrows) during follow-ups of 3 months and 6 months (e) while focally recovering with CC perfusion (blue arrow)
