Original Article


The authors have verified that retina dysfunction in patients suffering from chronic pancreatitis could be demonstrated by the help of electroretinography and eliminated or significantly corrected by administration of pancreas enzyme preparations. The retinograph may be applied successfully in the diagnosis of chronic pancreatitis and also in evaluation of the efficacy of the substitution treatment. The insufficiency of zinc absorption may play a definite role in the development of these functional disturbances. It has also been established that lower zinc values parallel with the decrease of the stool fat contents in patients suffering from chronic pancreatitis and can be significantly improved by enzyme preparations.
