ICGA is useful to evaluate choroidal perfusion in choroidal inflammatory disease. Dark dots may appear on ICGA which may represent choroidal granuloma, choroidal nonperfusion, or even infarcts. Some examples of inflammatory conditions in which ICGA is useful include multiple evanescent white dot syndrome (Fig. 26), Vogt-Koyanagi-Harada disease (Fig. 27) [15], multifocal choroiditis, Behçet's disease (Fig. 28), acute multifocal posterior placoid pigment epitheliopathy [16], and ocular histoplasmosis syndrome. Secondary CNV may develop as a complication of inflammation. FA can help to differentiate active CNV from chorioretinal granuloma or RPE scars (Fig. 29).
