Bilateral simultaneous anterior ischemic optic neuropathy (AION) is uncommon. We report a case of bilateral and nearly simultaneously occurring AION.
A 61-year-old man was referred to our hospital with bilateral optic disc edema.
Visual field testing demonstrated inferior nasal defect OD and inferior defect OS. Fluorescein angiography showed a delay of dye filling in the superior part of the optic disc in both eyes. The patient had poorly controlled diabetes. A mild increase in erythrocyte sedimentation rates and creactive protein was observed, but the results of temporal artery biopsy were negative. His optic discs were small and lacked biological cups, which has been identified as a risk factor for developing AION.
The complications of the structural anomaly, also known as "disc at risk," and diabetes might have caused the bilateral and nearly simultaneously occurring AION.
双侧同时性前部缺血性视神经病变（AION）并不常见。我们报告一例双侧几乎同时发生的AION病例。
一名61岁男性因双侧视盘水肿被转诊至我院。
视野检查显示右眼下方鼻侧缺损，左眼下方缺损。荧光素血管造影显示双眼视盘上部染料充盈延迟。该患者糖尿病控制不佳。观察到红细胞沉降率和C反应蛋白轻度升高，但颞动脉活检结果为阴性。他的视盘较小且无生理杯，这已被确定为发生AION的一个危险因素。
结构异常并发症，即所谓的“高危视盘”，以及糖尿病可能导致了双侧几乎同时发生的AION。
