The paper propose the study of lacrimal secretion alterations, the lacrimal level of the urea and the fundus optic alterations at the patients with chronic renal failure, during the hemodialysis. For the study we used the general ophthalmologic examination, the fundus optic examination before and after the hemodialysis, the lacrimal secretion examination by Schirmer l-test and the measure of lacrimal urea by the Berthelot modified method. The study was done on a member of 30 patients, with chronic renal failure, having a age of the dialysis between one and 80 months. The results of the study showed lacrimal hyposecretion, the urea lacrimal level being lower than the urea blood level and a concordance between the lacrymal and sanguine clearance of the urea. The fundus optic examination during the hemodialysis showed a pale aspect of the fundus the pallidity being more pronounced before the dialysis with filiforme arterioles, apparently without content, significant for decreasing of the circulatory debit.
