目的:探讨眼底荧光血管造影不能确定出血原因的黄斑出血的原发病灶。方法:对18例(20眼)不明原因黄斑出血作了吲哚青绿脉络脉络膜血管造影检查及分析。结果:本文结果表明导致不明原因黄斑出血的原发病灶有三类:脉络膜新生血管形成、视网膜血管异常和黄斑区偶发性出血。其中脉络膜新生血管导致的不明原因黄斑出血占多数(14眼),而由视网膜血管异常(3眼)和黄斑区偶发性出血(3眼)所致的不明原因黄斑出血比率较少。结论:吲哚青绿脉络膜血管造影对揭示不明原因黄斑出血的原发病灶有非常重要的价值。眼科学报 1997;13:62～66。
Objective: To investigate the primary lesion of macular hemorrhage in which fundus fluorescein angiography can not determine the cause of bleeding. Methods: 18 cases (20 eyes) of unidentified macular hemorrhage were examined by indocyanine green choroidal angiography. RESULTS: Our results show that there are three types of primary lesions leading to unexplained macular hemorrhage: choroidal neovascularization, retinal vascular abnormalities, and incidental macular hemorrhage. Choroidal neovascularization led to the majority of unidentified macular hemorrhage (14 eyes), while the proportion of unexplained macular hemorrhage due to retinal vascular abnormalities (3 eyes) and macular episode (3 eyes) was less. Conclusion: Indocyanine green choroidal angiography is of great value in revealing the primary lesion of unexplained macular hemorrhage. Journal of Ophthalmology 1997; 13: 62 ~ 66.
