Abstract

PURPOSE: To estimate the prevalence of dry eye among video-terminal (VDT) users and to assess risk factors for dry eye in this population. STUDY DESIGN: A single-centre, cross-sectional study was carried out on subjects employed as VDT workers and on a control group. METHODS: Demographic data, years spent working at a VDT, number of effective hours at VDT/day, number and hours of breaks/day were considered. All subjects underwent a complete ophthalmic examination and completed the Italian version of the computer vision symptom scale 17-item (CVSS17) questionnaire. Both groups were classified as definite, suspect and non-dry eye syndrome (DES). RESULTS: One-hundred and ninety four subjects completed the study; 70 (36.1%) of which represented the control group, and 124 (63.9%) represented the VDT group. Among VDT workers, 29 (23.4%) presented definite DES and 55 (44.4%) suspect DES, while among controls, only 2 (2.9%) presented definite DES and 37 (52.8%) suspect DES. In the univariate analysis, the DES group was older (p
