2.5. Evaluation of the Ischemic Index and Leakage Index
LEAKAGE
Ischemic index and leakage index values were measured using ultrawide-field fluorescein angiography (UWFA) (During the treatment period (V2–V6), the participants were monitored for the safety and efficacy of the treatment. The ischemic and leakage indexes were first measured at baseline (V1) and subsequently at 2, 4, and 8 weeks after administration (V7, V8, and V9, respectively).
