目的：探讨出血型视网膜大动脉瘤及合并症的红外光反射成像（infrared light reflection, IR）和眼底荧光血管造影（fundus fluorescein angiography, FFA）的影像特征。方法：采用回顾性病例系列研究。收集2010年2月—2024年6月在河南省立眼科医院确诊的出血型视网膜大动脉瘤患者35例35眼，所有眼均行IR联合FFA检查，其中10眼行吲哚菁绿血管造影（indocyanine green angiography, ICGA）检查，分析视网膜大动脉瘤及其合并症的眼底影像学特点。结果：IR检查显示34眼视网膜大动脉瘤体呈囊状反射光。FFA检查显示27眼视网膜大动脉瘤呈囊样强荧光，此外，FFA检查还发现5眼伴视网膜分支静脉阻塞，1眼伴视网膜分支动脉阻塞。FFA组在视网膜大动脉瘤检出率低于IR组(P <0.05)。在10眼出血型视网膜大动脉瘤中，IR组和ICGA组在视网膜大动脉瘤检出率方面比较差异无统计学意义(P >0.05)。结论：IR检查对于出血型视网膜动脉瘤的检测可等效于ICGA检查，IR联合FFA检查适合于出血型视网膜大动脉瘤及合并症的个体化诊断。

Objective: To evaluate the imaging characteristics of infrared light reflection (IR) and fundus fluorescein angiography (FFA) in hemorrhagic retinal artery aneurysm and its complications. Methods: Retrospective case series study was used. The clinic data of 35 patients (35 eyes) were diagnosed in Henan Eye Hosptial from February 2010 to June 2024. All eyes were examinated by IR and FFA, and 10 eyes examinated by indocyanine green angiography (ICGA). The fundus imaging characteristics of hemorrhagic retinal artery aneurysm and its complications was analyzed. Results: The images of IR presented 34 eyes with cystic strong reflex light. FFA showed 27 eyes with cystic strong fluorescence, in addition, FFA revealed 5 eyes with retinal branch vein occlusion and 1 eye with retinal branch artery occlusion. The detection rate of hemorrhagic retinal artery aneurysm in the FFA group was lower than that in the IR group (P =0.038<0.05). There was no significant difference in the detection rate of hemorrhagic retinal artery aneurysm between the IR group and the ICGA group in 10 eyes with hemorrhagic retinal artery aneurysm (P =1.000>0.05). Conclusion: IR examination could be equivalent to ICGA examination for detecting hemorrhagic retinal artery aneurysm, and IR combined with FFA examination is suitable for individualized diagnosis of hemorrhagic retinal artery aneurysm and its complications.
