Evaluation of the Relationship Between Ocular Surface Disease Index and Dry Eye Test Parameters in Computer Users.

Aim: The present study aims to evaluate the relationship between ocular surface disease index (OSDI) and dry eye test parameters in computer users. Material and Method: In this current study, 62 individuals between the ages of 20 and 40 years and who spent at least 6 hours of their daily life in front of a computer were included. In addition to the complete ophthalmologic examination, dry eye tests including Schirmer I test, Schirmer II test, tear breakup time (TBUT), ocular surface fluorescein and lissamine green staining were performed on each volunteer for both eyes after completion of the OSDI questionnaire. Results: Of 62 participants, 42 (67.7%) were female and 20 (32.3%) were male. The mean age of participants was 30.06±4.794 (21-39) years. The mean computer use time of the participants was 10.15 ± 3.040 (6-16) hours/day. The mean OSDI score was 31.0742 ± 15.05892 (8.3-75). There was a significant negative correlation between OSDI score and TBUT in the right eye (r=-0.718, p=0.000) and the left eye (r=-0.667, p=0.000). However, there was a slightly negative correlation between OSDI score and Schirmer I-II tests in the right eye (r = -0.273, p = 0.032; r = -0.295, p = 0.020, respectively) and the left eye (r = -0.308, p = 0.015; r = -0.296, p = 0.019, respectively). There was a significant difference between OSDI score and ocular surface staining scores in both eyes (p=0.000). There was a significant positive correlation between OSDI score and computer use time (r=0.642, p=0.000). However, there was no correlation between age, gender, smoking, wearing glasses and OSDI score (p> 0.05). Conclusion: Long-term computer use and longer duration of occupation may lead to ocular surface problems. The OSDI was found to be strongly associated with daily computer use time, TBUT, and ocular surface staining scores in computer users. [ABSTRACT FROM AUTHOR]
