老年性黄斑变性96例的荧光眼底造影

Fluorescence angiography of 96 cases of age-related macular degeneration

目的探讨眼底荧光血管造影术（FFA）在诊断老年性黄斑变性中的意义。方法对96例老年性黄斑变性病人进行FFA；在4年中随访40例病人再次进行FFA。结果萎缩型黄斑变性FFA表现：有玻璃膜疣处荧光增强，随时间延长的减弱。渗出型黄斑变性FFA表现：早期见脱离区视网膜下新生血管有渗漏，荧光素积存于盘腔内有强荧光区，出血区显遮蔽荧光。40例随访造影结果：原诊断33例萎缩型有9例转为渗出型。而新生血管部位恰与玻璃膜疣聚集区融合相一致。结论视网膜下新生血管是导致视力丧失的主要因素。

Objective To evaluate the value of fluorescence angiography in diagnosis of age-related macular degeneration. Methods Fluorescence angiography was performed in 96 cases. 40 follow-up cases were reexamined by fluorescence angiography in 4 years. Results The manifestations of atrophy type of macular degeneration were enhanced fluorescence spots which weakened as time goes by. And the manifestations of exudation type were seepage in new vessel under the area of the early stage retinodialysis. The material of fluorescence accumulated in the area of high fluorescence and in the bleeding area the fluorescence was shaded. The atrophy type of 9 cases in 33 cases became exudation type. The area of new blood vessel was consistent with the aggregation and confluence area of glassy membrane verruca. Conclusion The new blood vessel under retina is the main factor leading to the anopsi.
