目的 明确吲哚菁绿眼底血管造影(ICGA)在检查视网膜静脉阻塞(RVO)中的临床应用价值。方法 使用海德堡共焦激光扫描检眼镜(HRA),对82例RVO患者进行同步的眼底荧光血管造影(FFA)和ICGA检查。结果(1)82例RVO在ICGA的全过程中均可清晰地看到视网膜血管充盈情况,14例因出血较多FFA中看不清血管充盈情况。(2)64例ICGA可见阻塞区视网膜毛细血管呈瘤状扩张,其中有12例因出血较多FFA中看不清。(3)分枝静脉阻塞病例,ICGA比FFA更清楚地观察到动静脉交叉压迫情况,有6例在阻塞点静脉内可见到栓子存在。(4)FFA有2例,ICGA有8例可见到脉络膜血管扩张,2例可见脉络膜充盈缺损。结论 将ICGA与FFA结合用于RVO检查比单纯FFA能为临床提供更多的信息。
Objective To determine the clinical value of indocyanine green fundus angiography (ICGA) in the diagnosis of retinal vein occlusion (RVO). Methods Eighty-two RVO patients underwent fundus fluorescein angiography (FFA) and ICGA examination using Heidelberg confocal laser scanning ophthalmoscope (HRA). Results (1) 82 cases of RVO in the entire process of ICGA can clearly see the retinal vessel filling situation, 14 cases of bleeding due to more bleeding can not see the filling of the FFA. (2) 64 cases of ICGA visible obstruction of retinal capillary tumor was dilated, of which 12 cases due to bleeding more FFA can not see. (3) Case of branch vein occlusion, ICGA more clearly observed arteriovenous cross-oppression than FFA, there are 6 cases of emboli in the occlusion vein can be seen. (4) 2 cases of FFA, 8 cases of ICGA can be seen choroidal vasodilation, 2 cases of choroidal filling defects can be seen. Conclusion The combination of ICGA and FFA for RVO can provide more clinical information than FFA alone.
