Nonrecurring transient cortical blindness after coronary angiography: a role for hypoventilation and hypercarbia?

Abstract
A 73-year-old morbidly obese patient suffered cortical blindness following coronary angiography. Symptoms rapidly resolved and did not recur following a repeated procedure. Hypoventilation due to narcotics with subsequent hypercarbia and blood-brain barrier breaching may be implicated in the pathogenesis of this complication.
