本文总结了我院１９８５年至１９９１年经病理证实的４０例脉络膜黑色素瘤。分析其临床、超声波、眼底荧光血管造影的特点及病理改变。并对荧光血管造影的病理机制进行初步探讨。眼底荧光血管造影中于肿瘤内的低荧由肿瘤细胞及其内色素、坏死、血窦等所致。而高荧主要由肿瘤内血管和其上脱落的变性的色素上皮细胞所致。
This article summarizes our hospital from 1985 to 1991 pathologically confirmed 40 cases of choroidal melanoma. Analysis of its clinical, ultrasound, fundus fluorescein angiography features and pathological changes. The pathological mechanism of fluorescein angiography was also discussed. Fundus fluorescein angiography in the tumor within the low fluorescence by the tumor cells and their pigment, necrosis, sinusoids caused. The high fluorescence mainly by the tumor vessels and shedding on its degeneration of the pigment epithelial cells caused.
