Temporary blindness, also known as transient cortical blindness, is an uncommon impediment of contrast agent usage during angiography procedures. The occurrence of blindness after a cardiac catheterization procedure is rare and its pathophysiology remains largely speculative. The most probable mechanism seems to be contrast agent-related disruption of the blood-brain barrier, possibly initiated by several predisposing factors. This case reports a 52-year-old man with transient vision loss that occurred following coronary angiography. Brain magnetic resonance imaging (MRI) showed no acute pathology and his vision spontaneously returned within approximately 15 hours post-procedure without any requirement of specific therapy. Suggesting that transient cortical blindness may have occurred following coronary angiography which subsequently self-resolved.
一过性失明，又称短暂性皮质盲，是血管造影术中对比剂使用的一种不常见障碍。心脏导管插入术后发生失明的情况较为罕见，其病理生理学仍在很大程度上推测。最可能的机制似乎是对比剂相关的血脑屏障破坏，可能由几个诱发因素引发。本病例报告了一位 52 岁男性，在冠状动脉造影后出现短暂的视力丧失。脑部磁共振成像（MRI）显示无急性病变，他的视力在大约 15 小时后自发恢复，无需任何特殊治疗。提示可能是在冠状动脉造影后发生了短暂性皮质盲，随后自行缓解。
