Abstract
Objectives: To evaluate dry eye symptoms and clinical tear film alterations in patients with chronic renal failure (CRF). Materials and methods: Thirty-five non-diabetic CRF patients undergoing hemodialysis, and 31 healthy individuals were enrolled. An ocular surface disease index questionnaire (OSDI) was administered, and after a complete ocular examination, Schirmer and tear break-up time (TBUT) tests were performed. Results: OSDI scores were significantly higher (p < 0.01) and TBUT tests were significantly lower (p = 0.01) in CRF patients than in the control group. Schirmer test results were also lower in the CRF patients group, but lacked statistical significance (p = 0.20). Conclusion: Patients with CRF should be advised to obtain an ophthalmic examination, especially for dry eye.
