A 50-year old, diabetic, hypertensive patient with post-CABG status developed complete loss of vision about one hour after coronary angiogram (CAG). Thorough ophthalmological and neurological examination as well as magnetic resonance imaging of brain especially of the occipital region revealed no abnormality. The patient had complete recovery of vision about 48 hours later. We could not document any specific cause or mechanism for the visual loss, although the selective vulnerability of occipital lobes to contrast agent toxicity (Cortical blindness) was the most likely underlying mechanism.
