Study: Dry eye as an occupational hazard for lecturers

I love seeing these reports about the practical and occupational side of dry eye. This one covers a lot of familiar ground, but it was fun to see a new group studied.

Investigation of Dry Eye Symptoms in Lecturers by Ocular Surface Disease Index Köksoy Vayısoğlu et al, Turk J Ophthalmol. 2019 Jun 27;49(3):142-148.


The aim of this study was to evaluate the prevalence of dry eye symptoms among lecturers.


The study included 254 lecturers employed at Mersin University. The lecturers were selected by simple random sampling from lists obtained from the personnel department. Data were obtained between November 15 and December 15, 2017 using a questionnaire developed by the researchers and the Ocular Surface Disease Index (OSDI). The data were evaluated using descriptive statistics, Student’s t-test, ANOVA, and correlation tests with the SPSS package program.


Of the lecturers who participated in the study, 52.8% were male and 47.2% were female, and the mean age was 39.29±9.41 years. According to OSDI scores, 20.5% of the participants had mild, 15% had moderate, and 36.5% had severe disease. There were significant differences in mean OSDI score based on sex (p<0.001), alcohol use (p=0.01), continuous drug use (p=0.03), wearing glasses (p=0.04), history of dry eye (p<0.001), and presence of dry eye symptoms (p<0.001). There were also significant differences between the OSDI score categories in terms of sex (p<0.001), smoking status (p=0.04), wearing glasses (p=0.03), history of dry eye (p<0.001), and presence of dry eye symptoms. The only factor significantly correlated with OSDI score was daily duration of computer usage (p=0.009).


Our study showed that a substantial proportion of lecturers experience dry eye symptoms, and OSDI scores were associated with daily duration of computer use. Determining the factors associated with dry eye is important for the planning of preventive interventions.
