결정체가 없이 재발성 황반출혈을 보인 환자들의 인도사이아닌 그린 형광안저촬영 소견

Abstract

PURPOSE: To evaluate the indocyanine green angiographic (ICGA) characteristics of the patients who had recurrent macular hemorrhage. METHODS: Medical records and ICGA were reviewed on 22 eyes of the 22 patients who had recurrent macular hemorrhage without retinal vasculopathy, drusen, and high myopia from March, 1998 to December, 2000. RESULTS: The early hyperfluorescent lesion of ICGA were located in the macula in 16 eyes (72.7%), multiple in 16 eyes (72.7%), and the shape of the lesions were polypoid in 13 eyes (59.1%). The other shapes were tubular in 6 eyes (27.3%), single hotspot in 2 eyes (9.1%), and finger-like in 1 eye (4.5%). The lesion showed late leaking in 17 eyes (77.3%), washout in 2 eyes (9.1%), and mixed type in 3 eyes (13.6%). CONCLUSIONS: The reasons of the difficulty in showing the typical ICGA characteristics of idiopathic polypoidal choroidal vasculopathy (IPCV) by OIS(ophthalmic imaging system) type angiography in the patients who had recurrent macular hemorrhage were insufficient early pictures and the display of that type of ICGA. To diagnose IPCV correctly in the patients who had recurrent macular hemorrhage, early pictures, the changes of the fluorescence through the mid and late phase, and the variable ICGA characteristics should be taken into consideration.
