原发性视网膜色素变性的眼底荧光造影图像分析

目的观察原发性视网膜色素变性患者眼底荧光血管造影的图像特征。方法按准入和排除标准选择患者30名,按国际通用方法进行眼底荧光血管造影,并对造影图像的特征进行分析。结果全部病例的造影图像均显示斑驳状透见荧光,其他较多的特征有色素斑块所致的荧光遮蔽、视网膜血管一致性变细和荧光渗漏,较少表现的还有毛细血管无灌注所致的充盈缺损以及黄斑荧光积存等。结论原发性视网膜色素变性的眼底荧光血管造影图像特征为视网膜色素上皮细胞病变所致的斑驳状透见荧光和荧光遮蔽,以及视网膜血管病变所致的视网膜血管一致性变细等。

Analyses of the fluorescence fundus angiography in primary retinits pigmentosa

Objective To observe features of the fluorescence fundus angiography in Primary Retinitis Pigmentosa.Methods Acording to diagnosis and exclusion criteria in retinitis pigmentosa,30 chosed patients were accepted the fluorescence fundus angiography test in international standard.Results Mottles transmitted fluorescence can be observes in all the funds,blocked fluorescence caused by pigment and tenuity retinal vessels were also observed in most of figures,while fewer changes such as fluorescence leakage acused by nonperfusion of retinal vessels and fluorescence acumulation in macula lutes can be seen in some patients. Conclusion Features of the fluorescence fundus angiography in primary retinitis pigmentosa are transmitted fluorescence and mottled blocked fluorescence caused by the damaged retinal pigment epithelium,and the tenuity retinal vessels because of damaged vessels.
