An unusual but dramatic complication of coronary angiography: Transient cortical blindness

A 52-year-old woman developed transient cortical blindness after coronary angiography. Its occurrence after coronary angiography is far less common. A possible mechanism of this complication may be contrast penetration of the blood–brain barrier with direct neurotoxicity to the occipital cortex. Patient outcome is excellent, with complete recovery expected within 24–48 h.
