Comparison of ocular-surface disease index questionnaire, tearfilm break-up time, and Schirmer tests for the evaluation of the tearfilm in computer users with and without dry-eye symptomatology

Abstract

Objective: To compare the diagnostic values of the Schirmers and tearfilm breakup time (TBUT) tests and the Ocular Surface Disease Index (OSDI) in dry-eye syndrome. Subjects and methods: Thirty-five employees of mraniye Training and Research Hospital who used computers in their daily work participated in this prospective study. All participants completed the OSDI. Following routine ophthalmologic examination, the TBUT and Schirmers test were undertaken and outcomes were compared. Results: The mean age was 29.09 +/- 6.73 (range 2046) years. Mean OSDI questionnaire, TBUT, and Schirmers test scores were detected as 37.12 +/- 19.05 (range 475), 11.37 +/- 3.69 seconds (range 418 seconds), and 25.80 +/- 8.43 mm (range 635 mm), respectively. There was a significant inverse correlation between the OSDI and TBUT scores (r = -0.385, P = 0.022). No significant correlation existed between the OSDI and Schirmers test scores. Conclusion: Dry eye is a common problem among computer users. The OSDI questionnaire, used together with the TBUT, is easily performed and may be of benefit in supporting the diagnosis of dry-eye syndrome.
