Abstract
Hepatic cortical blindness is an unusual clinical complication of hepatic encephalopathy,
and its epidemiology has not been studied in detail. Herein, we present a case report
of a 37-year-old male with liver cirrhosis and immunoglobulin A nephropathy who noted
visual impairment after eating high-protein food. In addition to the case report,
all previously documented cases of hepatic cortical blindness occurring across the
globe published from inception until August 2019 were reviewed. The incidence of hepatic
cortical blindness is low, and diagnoses are easily missed. The diagnosis of hepatic
cortical blindness is dependent on symptoms, and patients may experience several attacks
of vision loss. Most patients experience complete blindness, but vision loss recovers
within 10 min to one month. Early detection and therapy for hepatic encephalopathy
may improve patient outcome.
