[Tears' immunology in acute eye diseases]. / Imunologia lacrimilor în afectiuni oculare acute.

The aim of the study is to research the immunoglobulins' concentration into the tears liquid and into the blood serum at the patients with acute affections of the anterior ocular pole. The study was accomplished on two groups of patients: one group with herpetic Keratitis, the other with anterior uveitis, the second having a different etiology--that the viral one. Another group of patients with senile cataract was used like witness-group. The immunoglobulins concentration were detected into the serum and into the tears by the Mancini method of the radial immunodiffusion. The results indicate a general immunodefficiency signed by the decrease of IgG and IgM into the serum on the one hand, and the increase of local defense mechanisms reflected on the growing of IgA and IgG level into the tears, on the other hand.

[The ocular changes in patients on chronic dialysis]. / Modificari oculare la bolnavii dializati cronic.

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.
