Transient cortical blindness after coronary angiography is a rarely encountered, rapidly progressive complication with complete return of vision within hours to up to five days.. Patients at risk include those undergoing coronary artery bypass graft study and those with renal failure. Although, the exact mechanism is not clear, the most likely explanation is a breakdown of blood brain barrier with direct neurotoxicity of the contrast media as most reported patients underwent coronary bypass graft study. We report a case of transient cortical blindness following diagnostic coronary angiography in a 39-year old patient with spontaneous recovery of vision within 1 hour.
冠状动脉造影术后短暂性皮质盲是一种罕见的、进展迅速的并发症，视力可在数小时至最多五天内完全恢复。高危患者包括接受冠状动脉搭桥手术的患者和肾衰竭患者。虽然确切机制尚不清楚，但最可能的解释是血脑屏障破坏以及造影剂的直接神经毒性，因为大多数报告的患者都接受了冠状动脉搭桥手术。我们报告一例39岁患者在诊断性冠状动脉造影术后发生短暂性皮质盲，视力在1小时内自发恢复。
