Abstract
Cortical blindness refers to the loss of vision produced by lesions affecting geniculocalcarine visual pathways. The most common causes of cortical blindness are ischemic stroke, cardiac surgery, and cerebral angiography. Its characteristic clinical manifestations are: (1) bilateral partial or total blindness, (2) intact pupillary light reflexes and no abnormality in extraocular muscle movements, (3) normal ophthalmoscopic finding, (4) optokinetic nystagmus (may or may not be present). The possible mechanism of angiography-related cortical blindness is neurotoxicity of the contrast agents. Transient, symmetric enhancement in bilateral occipital lobes in CT or MRI is observed frequently. EEG is also an important diagnostic method. No specific treatment is known as effective, but several possible methods are suggested. We presented a case of transient cortical blindness after bronchial arteriography.
