Abstract

Background

Acute unilateral vision loss is an ophthalmological emergency. It can have multiple aetiologies, and physicians must be able to quickly determine the cause of the condition, as immediate intervention may prevent permanent vision loss. Acute unilateral vision loss has not previously been associated with a patent foramen ovale (PFO).

Objective

We describe a patient who presented with painless sudden loss of vision in his left eye. He was diagnosed to have central retinal artery occlusion, likely from a paradoxical embolus associated with an atrial septal aneurysm containing a PFO. The patient underwent successful percutaneous closure of the PFO without complication. This report details the evaluation and differential diagnosis of acute unilateral vision loss. Additionally, the controversy of whether a PFO should be closed prophylactically for stroke prevention is discussed.

Conclusion

Acute unilateral vision loss from central retinal artery occlusion may be caused by a paradoxical embolus originating from an atrial septal aneurysm with a PFO. This case should be considered in the controversy of whether prophylactic closure of a PFO could be beneficial for primary prevention of stroke.

与房间隔动脉瘤和卵圆孔未闭相关的视网膜中央动脉阻塞引起的急性单侧视力丧失：病例报告

摘要

背景

急性单侧视力丧失是眼科急症。它可能有多种病因，医生必须能够快速确定病因，因为立即干预可以防止永久性视力丧失。急性单侧视力丧失以前未与卵圆孔未闭 (PFO) 相关。

客观的

我们描述了一名左眼无痛性突然失明的患者。他被诊断出患有视网膜中央动脉阻塞，可能来自与含有 PFO 的房间隔动脉瘤相关的反常栓子。患者成功经皮闭合 PFO，无并发症。本报告详细介绍了急性单侧视力丧失的评估和鉴别诊断。此外，还讨论了是否应为预防卒中预防性关闭 PFO 的争议。

结论

视网膜中央动脉阻塞导致的急性单侧视力丧失可能是由 PFO 的房间隔动脉瘤引起的反常栓子引起的。在关于预防性关闭 PFO 是否有益于卒中一级预防的争议中，应考虑该病例。
