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.

ÖZET
 Amaç: Bu çalışmanın amacı, uzun süreli bilgisayar kullanıcılarında kısa dönem (hafta içi dönem) kuru göz parametreleri, gözyaşı menisküsü yüksekliği ve epitel kalınlığındaki değişiklikleri araştırmak. Gereç ve Yöntemler: Günde en az 6 saat bilgisayar kullanan, kuru göz semptomları olan 23 hastanın 46 gözü çalışmaya dâhil edildi. Schirmer testi, gözyaşı kırılma zamanı (GKZ), oküler yüzey hastalığı indeksi (OYHİ) skoru, epitel kalınlığı ve gözyaşı menisküs seviyeleri spektral domain optik koherens tomografi ile kaydedildi. Hastaların tüm ölçümleri pazartesi günü işe başlamadan önce sabah (1. vizit) ve aynı hafta cuma günü iş çıkışı (2. vizit) ilaçsız tekrarlandı. Bulgular: GKZ değerleri 1 ve 2. vizitte sırasıyla ortalama 12,41±2,68 sn, 9,69±2,39 sn (p<0,001); Schirmer test değerleri 20±5,47 mm, 11,89±3,62 mm (p<0,001); gözyaşı menisküs seviyeleri 158,65±41,18 μm, 118,15±31,99 μm (p<0,001); OYHİ skorları 12,13±4,89, 18±5,50 (p<0,001); santral kornea epitel kalınlıkları 33,5±5,81 μm, 33,19±6,10 μm (p=0,703) idi. Santral kornea epitel kalınlığı açısından 2 vizit arasında anlamlı fark yoktu (p=0,703). Sonuç: Kısa süre hafta içi döneminde, uzun süreli bilgisayar kullanıcılarında OYHİ skoru, GKZ, schirmer ve gözyaşı menisküs düzeylerinde değişiklikler gözlenirken, merkezi kornea epitel kalınlığı üzerinde değişiklik yoktu.
