ObjectiveTo compare the effects of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) on classifications and locations of choroidal neovascularization (CNV) located under subretinal hemorrhage in age-related macular degeneration, and on the areameasuring of subretinal hemorrhage.MethodsThe medical record of 177 patients with subretinal hemorrhage associated with AMD confirmed by photochrome of ocular fundus, FFA and ICGA examinations were retrospectively reviewed. The locations and classifications of CNV on the images of FFA and ICGA in the 177 patients and the area of subretinal hemorrhage of 30 patients randomly selected from the 177 patients were analyzed and measured. ResultsOn the images of FFA, the locations and classifications of CNV could be defined in 160 patients (90.4%), and CNV was considered eligible for laser therapy in 24 patients (13.6%). On the images of ICGA, the locations and classifications of CNV could be defined in 175 patients （98.9%），and CNV was considered eligible for laser therapy in 51 patients (28.8%). There was no statistical difference of the locations（Z=-0.383，P=0.701） and classifications （ χ2=2.993，P=0.810） of CNV on the images of FFA and ICGA. The areas of blocked fluorescence measured on the images of FFA (x-=26.610 mm2 and M=13.548 mm2) were larger than those of ICGA (x-=24.714 mm2，M=12.875 mm2) with statistical differences （Z=-3.000，P=0.003） between FFA and ICGA. ConclusionsICGA is beneficial for imaging CNV located under subretinal hemorrhage, and may increase the number of the patients who are considered eligible for laser treatment. The effect of measurement of the area of subretinal hemorrhage in AMD evaluated by FFA is better. (Chin J Ocul Fundus Dis,2003,19:149-151)
