目的 观察和评价萎缩型老年性黄斑变性 ( age- related macular degeneratioin,AMD)的荧光素眼底血管造影 ( fundus fluorescein angiography,FFA)与吲哚青绿血管造影 ( indocyanine green angiogra-phy,ICGA)图像特征和对比检查的应用价值。 方法 回顾分析 73例萎缩型 AMD患者 95只眼的彩色眼底照相、FFA和 ICGA检查资料 ,其中包括视网膜色素上皮 ( retinal pigment epithelium,RPE)色素脱失与萎缩 19例 2 6只眼、玻璃疣 15例 30只眼和 39例单侧渗出性 AMD患者的对侧眼 39只。 结果 2 6只RPE色素脱失与萎缩的眼中 ,2 4只色素脱失眼 FFA表现为晚期斑片状强荧光 ,ICGA表现为斑片状强弱相间荧光 ;地图状萎缩 2只眼 ,FFA表现为斑片状强荧光 ,ICGA表现为边界清晰的弱荧光内见脉络膜毛细血管缺损 ,仅有脉络膜大血管。 8只硬性玻璃疣眼 FFA表现为强荧光 ,ICGA表现为持续斑点状强荧光 ;16只软性玻璃疣眼 FFA表现为强荧光 ,ICGA表现为持续性斑片状强弱相间荧光 ;6只同时有软性和硬性玻璃疣眼 FFA表现为强荧光 ,ICGA表现为斑点状强弱相间荧光。当玻璃疣 ICGA表现为弱荧光时 ,FFA所见到的玻璃疣的数量及范围较 ICGA所见者更多更大 ;当玻璃疣 ICGA表现为强荧光时 ,FFA检查所见到的玻璃疣的数量及范围较 ICGA?
Objective To observe and evaluate the imaging features of fundus fluorescein angiography (FFA) and indocyanine green angiogra-phy (ICGA) in age-related macular degeneratioin (AMD) The value of comparative inspection. Methods The color fundus photography, FFA and ICGA examination data of 95 eyes of 73 patients with atrophic AMD were retrospectively analyzed. Among them, 19 cases had 26 cases of retinal pigment epithelium (RPE) depigmentation and atrophy, 15 cases of drusen 15 Thirty-nine eyes and 39 unilateral exudative AMD patients had 39 contralateral eyes. Results In the eyes of 26 RPE patients with atrophy and atrophy of the RPE, 24 cases of depigmented depigmentation showed abnormal late patchy fluorescence and ICGA showed patchy weakness and interphase fluorescence. For the patchy strong fluorescence, ICGA showed a clear boundary weak fluorescence see choroidal capillary defect, only the choroidal blood vessels. FFA showed strong fluorescence in 8 eyes of rigid glass warts, and persistent macular fluorescence in ICGA. FFA showed strong fluorescence in 16 eyes with soft glass warts, and persistent macular fluorescence with intermittent patches in ICGA; Soft and hard glass warts eye FFA showed strong fluorescence, ICGA showed speckle-like phase of the interphase fluorescence. The number and extent of drusen found by FFA were greater and greater than those seen by ICGA when drusen ICGA showed weak fluorescence; when drusen ICGA showed strong fluorescence, drusen found by FFA The number and scope of ICGA?
