摘要

目的:描述一例视网膜动脉大动脉瘤病例,这是一种罕见的局灶性动脉扩张,通常发生在视网膜动脉分叉的前三阶。方法:对一份观察性病例报告进行评估。结果:一名 49 岁的男性,患有糖尿病前期和高胆固醇血症,因视力下降和右眼旁中心性视网膜病变而就诊。他的眼科病史不详。视网膜内和视网膜下有大量积液,眼底周围有渗出物。在初步诊断为视网膜分支静脉闭塞的情况下,他接受了两次阿弗利百普的玻璃体内注射,但情况没有改善。静脉荧光素血管造影显示,距离眼窝血管缺失区不到60微米处有一个小的视网膜动脉大动脉瘤,该瘤接受了低功率局灶激光光凝治疗。治疗后,黄斑水肿完全消退,视力明显改善。结论:这例罕见的、成功治疗的渗出性同侧视网膜动脉大动脉瘤病例凸显了多模态成像在确定准确诊断方面的重要性。

Juxtafoveal Retinal Arterial Macroaneurysm Diagnosed on Ancillary Imaging
Purpose: To describe a case of retinal arterial macroaneurysm, a rare, focal arterial dilatation that is commonly found temporally within the first 3 orders of retinal arterial bifurcations. Methods: An observational case report was evaluated. Results: A 49-year-old man with prediabetes and hypercholesteremia presented with decreasing vision and a paracentral scotoma in the right eye. His ocular history was insignificant. There was significant intraretinal and subretinal fluid with perifoveal exudates. After 2 intravitreal injections of aflibercept for a tentative diagnosis of branch retinal vein occlusion, there was no improvement. Intravenous fluorescein angiography showed a small retinal arterial macroaneurysm less than 60 µm from the foveal avascular zone that was treated with low-power focal laser photocoagulation. This resulted in complete resolution of the macular edema with significant improvement in visual acuity. Conclusions: This rare and successfully treated case of an exudative juxtafoveal retinal arterial macroaneurysm highlights the importance of multimodal imaging in establishing an accurate diagnosis.
