摘要
目的 探讨眼底荧光血管造影 (FFA)在老年黄斑变性诊断中的应用价值。 方法 用Kuwafx 5 0 0型眼底照相机对老年黄斑变性 (AMD)患者进行FFA检查 ,并结合临床其他检查进行分析。 结果 5 1例AMD患者 6 5只眼中 ,萎缩型 42只眼 (6 4 6 % ) ,渗出型 2 3只眼 (35 4% )。萎缩型表现均为点状或斑驳样透见荧光 ,未见荧光素渗漏。渗出型早期可见脉络膜新生血管形态 (CNV) ,晚期大量荧光素渗漏 ,周围有出血者则表现为荧光遮蔽。 结论 对AMD患者早期应用FFA检查有助于发现CNV ,并显示其范围和部位 ,为治疗提供依据。
Objective To evaluate the fundus fluorescein angiography (FFA) for the diagnosis of age related macular degeneration (AMD). Methods AMD patients were examined by FFA using Kuwa fx 500 fundus camera and analysed in combination with other clinical examinations. Results In total of 65 eyes in 51 AMD patients, 42 eyes(64 6%) were diagnosed atrophic type, 23 eyes (35 4%) exudative type. The atrophic type showed spots or mottled shape in fluorescence transmission, and no fluorescein leakage was found. In the early stage of exudative type, choroidal neovascules could be seen and in the later stage, there was a lot of fluorescein leakage; the blocked fluorescence was observed if hemorrhage formed around. Conclusions The application of FFA helps making early diagnosis of AMD and pointing out the area and location of subretinal neovascular formation.
