Hepatic encephalopathy is a frequent and often fatal manifestation of chronic liver disease. The pathogenesis of hepatic encephalopathy is believed to be multifactorial including impaired blood-brain barrier function, imbalance between the excitatory and inhibitory neurotransmitters in cortex, accumulation of various toxic and false neurotransmitters, and lack of nutrients like oxygen and glucose. Signs and symptoms of hepatic encephalopathy varies and commonly ranges from personality changes, disturbed consciousness, sleep pattern alternation, intellectual deterioration, speech disturbances, asterixis to frank coma and even death. Reversible or transient cortical blindness is rare manifestation of hepatic encephalopathy. It may even precede the phase of altered consciousness in such patients. Very few similar cases have been reported worldwide. Hence, we would like to report a case of transient cortical blindness in a patient of hepatic encephalopathy.
