Table 1. Commonest Causes of Cortical Blindness Following Coronary Angiography
Cerebrovascular disease secondary to embolism (thrombus or atheroma), in situ thrombosis or intracerebral hemorrhage.
Catheter-related vasospasm of cerebral vessels.
Intimal tears causing dissection of the aortic arch and its branches.
Contrast-induced cortical blindness.
Hypotension, which may be contrast-induced.
In addition, cortical blindness has been observed in patients following head trauma and in those with uremia, meningitis and hysteria.
