Doubts still exist concerning the mechanisms involved in ocular ischemic syndrome (OIS) and its dependence on carotid disease. We report findings from 14 surgical patients undergoing carotid artery reconstruction for symptomatic cerebrovascular disease. All of them had fluorescein angiography (FA) of the eye ipsilateral to the carotid operation before surgery and 3 months after to provide information regarding retinal circulation time. Before the surgical procedure, the mean circulation time was 29.4 ± 9.4 seconds (CI 95%: 24.5-34.3). After 3 months, a significant (P < .001) decrease in the circulation time was observed: 18.9 ± 8.4 seconds (CI 95%: 14.5-23.4). The present series demonstrates that carotid revascularization surgery improved retinal flow in approximately 80% of the patients.
关于眼局部缺血综合征（OIS）及其对颈动脉疾病的依赖性的机制仍存在疑问。我们报告了 14 例因症状性脑血管病而行颈动脉重建术的手术患者的结果。所有患者在手术前和手术后 3 个月均行同侧眼荧光素血管造影（FA），以提供视网膜循环时间的信息。在手术前，平均循环时间为 29.4 ± 9.4 秒（95%CI：24.5-34.3）。3 个月后，循环时间明显（P<.001）缩短：18.9 ± 8.4 秒（95%CI：14.5-23.4）。本系列表明，颈动脉血运重建术改善了约 80%患者的视网膜血流。
