The visual evoked potential (VEP) record in response to a pattern stimulus is a non invasive and reliable method of detecting central and peripheral nerve system abnormalities. VEP recording have been used in animals with @entity879 , and also in- @entity1 with @entity99 and acute severe @entity99 . Our aims were: a. to evaluate the potency of PVEP in assessing @entity99 . b. to find the rate of pathologic PVEP in @entity1 with advanced liver @entity82 . VEP was recorded in 14 chronic liver cirrhotic @entity1 (6 alcoholic, 6 @entity3531 -related, 2 cryptogenic) and 14 controls. @entity1 with any @entity16 were excluded from the study. All @entity1 were subjected to the @entity1032 ( @entity1032 ) test, and venous blood @entity3265 was measured on the same day of VEP recording. In 10/14 (71%) @entity1 some VEP recording abnormality was detected. In the cirrhotic @entity1 , @entity9508 latency was significantly longer (P < 0.05) than in controls. Low amplitude was observed in 8 @entity1 compared to controls. Marked increase of N75 (3 @entity1 ) and marked increase of N145 (2 @entity1 ) were observed. Mean blood ammonia and @entity1032 score were normal in all @entity1 . No correlation was found between both @entity1032 score and blood ammonia levels and the @entity9508 delay. Five out of 10 @entity1 with pathologic VEP developed hepatic encephalpathy during a follow-up of one year, compared to one out of 4 @entity1 with no pathology on VEP recording. VEP recording may be a valuable tool in assessing @entity1 with early @entity99 and in predicting @entity75 .
