摘要
目的:探讨高度近视性黄斑出血在吲哚青绿血管造影(in-docyaninegreenangiography,ICGA)中的特征。方法:对68例(69眼)高度近视性黄斑出血患者的ICGA图像回顾性分析。结果:ICGA显示该69眼(100%)均有呈线状低荧光表现的漆样裂纹,提示脉络膜毛细血管与Bruch膜组成的复合体破裂。在25眼未有脉络膜新生血管(choroidalneo-vascularization,CNV)生成的眼内(36%),ICGA后期像显示黄斑出血区域为圆形低荧光,其间有漆样裂纹。在44眼(64%)内,ICGA显示黄斑出血与CNV有关,而CNV均与漆样裂纹相连。结论:脉络膜毛细血管与Bruch膜组成的复合体破裂或CNV可造成高度近视性黄斑出血。ICGA是区别高度近视性黄斑出血原因的有效检查方法。
AIM： To evaluate the characteristics of indocyanine green angiography （ICGA） of macular hemorrhage in pathological myopia. METHODS： The images of 68 patients （69 eyes） of pathological myopia with macular hemorrhage were analyzed retrospectively. RESULTS： ICGA revealed linear hypofluorescence of lacquer cracks in all the 69 eyes （100%）, indicating a rupture of complex of choriocapillaris and Bruch＇s membrane. In 25 eyes （36%）, the macular hemorrhage without choroidal neovascularization （CNV） showed oval-shape hypofluorescent lesion at later phase of ICGA, appearing at the site of lacquer crack. In 44 eyes （64%）, ICGA revealed macular hemorrhage corresponding to CNV, which connecting with lacquer crack.
CONCLUSION： Rupture of complex of choriocapillaris and Bruch＇s membrane or CNV causes macular hemorrhage of pathological myopia, ICGA is effective to differentiate the cause of macular hemorrhage of pathological myopia.
