目的:探讨眼底荧光造影(fundus fluorescein angiography,FFA)在老年黄斑变性诊断中的应用价值。方法:用Topocon TRC-NW7SF型眼底照相机对老年黄斑变性(age related macular degeneration,AMD)患者进行FFA检查,并结合临床其他检查进行分析。结果:AMD患者40例62眼中,萎缩型49眼(79%),渗出型13眼(21%)。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(choroidal neovascularization,CNV)形态,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检查有助于分析CNV,并显示其范围和部位,为治疗提供依据。

·AIM:To evaluate the fundus fluorescein angiography(FFA)for the diagnosis of age related macular degene-ration(AMD).·METHODS:AMD patients were examined by FFA using Topocon TRC-NW7SF fundus camera and analysed in combination with other clinical examinations.·RESULTS:In total of 62 eyes in 40 AMD patients,49 eyes(79%)were diagnosed as atrophic type,13 eyes(21%)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 neovascularization(CNV)could be seen,and in the later stage,there was a lot of fluorescein leakage;the blocked fluorescence was observed if hemorrhage formed around.·CONCLUSION:The application of FFA helps the early diagnosis of AMD and points out the area and location of CNV.·
