Abstract：
OBJECTIVE: To investigate the recurrent non-arteritic retinal artery occlusion (RAO) in the same or opposite eye.
METHODS: We searched the RAO registry at Seoul National University Bundang Hospital and included patients with recurrent RAO in the present study. Ophthalmic and systemic features were analysed to identify risk factors and visual outcomes.
RESULTS: Of the 850 patients in the non-arteritic RAO cohort, 11 (1.3%) experienced a second RAO recurrence, either in the same (5 patients; 0.6%) or opposite (6 patients; 0.7%) eye. The same eye group experienced an earlier recurrence (1-2 months, median 1 month) than the opposite eye group, where the time to recurrence was notably longer (8-66 months, median 22 months). Best corrected visual acuity (BCVA) in the same eye group decreased after the recurrence of RAO. In the same eye group, initial BCVA ranged from 20/200 to counting fingers (CF), while BCVA during RAO recurrence ranged from CF to hand motion. When RAO recurred in the opposite eye, the reduction in visual acuity was less severe than the reduction of the initial episode: initial episode ranged from 20/400 to light perception and recurrent episode ranged from 20/25 to 20/400. Patients exhibited varying degrees of carotid (81.8%) and cerebral (9.1%) artery occlusions. Additionally, one patient in each group (total 2 patients, 18.2%) experienced a stroke 6 months after RAO recurrence.
CONCLUSIONS: Since the RAO recurrences could lead to devastating visual impairment, it is essential to emphasise the importance of risk factor screening to patients while collaborating with neurologists and cardiologists.

摘要：
目的：探讨非动脉炎性视网膜动脉阻塞(RAO)在同眼或对眼的复发。
方法：我们检索了首尔国立大学Bundang医院的RAO注册，并将复发性RAO患者纳入本研究。分析了眼科和全身特征，以确定危险因素和视觉结果。
结果：在非动脉炎性RAO队列的850名患者中，11人（1.3%）经历了第二次RAO复发，无论是在同一眼（5例；0.6％）或相反（6例；0.7％）。同一组眼睛经历了较早的复发（1-2个月，中位数1个月)比相反的眼睛组，复发时间明显更长（8-66个月，中位数22个月)。同一眼组的最佳矫正视力（BCVA）在RAO复发后下降。在同一个眼睛组中，初始BCVA范围从20/200到计数手指（CF），而RAO复发期间的BCVA范围从CF到手部运动。当RAO在另一只眼睛复发时，视力下降的严重程度低于初始发作的减少:初始发作范围为20/400至轻度感觉,复发发作范围为20/25至20/400.患者表现出不同程度的颈动脉（81.8％）和大脑（9.1％）动脉闭塞。此外,每组一名患者(共2名患者，18.2%）在RAO复发后6个月出现卒中。
结论：由于RAO复发可能导致破坏性视力损害，在与神经科医师和心脏病学家合作的同时,必须强调对患者进行危险因素筛查的重要性.
