老年性黄斑变性,尤其是渗出型,系老年中最常见的致盲病因。自1968年始,许多作者应用氩激光凝固治疗此病,但其结果不一。本文报道76眼,术前均行荧光素眼底血管造影术。随访期为1个月至4年。共75例患者,年龄自55～87岁,平均72岁。根据临床表现及荧光素血管造影图像将此疾患分成3种类型:(1) 色素上皮脱离(高度浆液性色素上皮脱离、无视网膜下血管增生);(2)视网膜下血管膜(黄斑水肿伴有广泛视网膜下血管增生);(3)出血型(大量黄斑区出血伴有视网膜下血管膜)。第1型的病灶常向颞侧扩展,可使用氩激光凝固器对脱离的颞侧部分作烧灼。而对其他二型则作局灶性光凝。
Age-related macular degeneration, especially exudative, is the most common cause of blindness in old age. Since 1968, many authors have used argon laser to treat the disease, but the results are mixed. This article reports 76 eyes, preoperative fluorescein fundus angiography. Follow-up period of 1 month to 4 years. A total of 75 patients, aged from 55 to 87 years, mean 72 years. According to the clinical manifestations and fluorescein angiography images the disease is divided into three types: (1) pigment epithelial detachment (highly serous pigment epithelial detachment, no subretinal vascular proliferation); (2) subretinal vascular membrane (macular edema associated with Extensive subretinal vascular proliferation); (3) hemorrhagic (a large number of macular hemorrhage associated with subretinal vascular membrane). Type 1 lesions often extend to the temporal side, and the temporal portion of the detachment can be cauterized using an argon laser coagulator. While the other two type for focal photocoagulation.
