Uzun Süreli Bilgisayar Kullanıcılarında Kuru Göz Parametreleri, Gözyaşı Menisküs Yüksekliği ve Kornea Epitel Kalınlığının Kısa Süreli Hafta İçi Çalışma Periyodundaki Değişimi: Kohort Çalışması

Abstract

Objective: To investigate the changes in dry eye parameters, tear meniscus height and epithelial thickness over a shortterm period (working week) in long-term computer users. Material and Methods: There were 46 eyes of 23 patients with dry eye symptoms who used computers for at least 6 h per day were included in this study. The Schirmer's test scores, tear break-up time (TBUT), ocular surface disease index (OSDI) score, epithelial thickness and tear meniscus levels by spectral domain-optical coherence tomography were recorded. All measurements of the patients were repeated on Monday morning before starting work (first visit) and on Friday of the same week after work (second visit) without medication. Results: The mean TBUT values were 12.41±2.68 s, 9.69±2.39 s, the Schirmer's test values were 20±5.47 mm, 11.89±3.62 mm (p<0.001); the tear meniscus levels were 158.65±41.18 μm, 118.15±31.99 μm (p<0.001); the OSDI scores were 12.13±4.89, 18±5.50 (p<0.001); and the central corneal epithelium thicknesses were 33.5±5.81 μm, 33.19±6.10 μm (p=0.703) upon the first and second visit, respectively. There was no significant difference in central corneal epithelial thickness (CET) between the two visits (p=0.703). Conclusion: While changes in the OSDI score, the TBUT, the Schirmer's test score and the tear meniscus levels were observed in long-term computer users in the short-term working week period, there was no short-term effect on central CET.
