Abstract
Cortical blindness (CB) is characterized by bilateral vision loss secondary to occipital lobe lesions. The most common causes of CB are bilateral occipital lobe infarction, hypoxemia, and toxic exposure. Complications of hypoxic-ischemic encephalopathy (HIE) usually appear immediately after cardiopulmonary resuscitation. Multifocal myoclonus is a recognized late complication of HIE; however, delayed occurrence of bilateral visual loss associated with HIE is rarely reported. We reported a case of delayed CB (5 days) after cardiac arrest in 33-year-old man. Physicians should be aware of this condition, even if patients have normal vision early after regaining consciousness.
