In this study, it was aimed to
determine the prevalance of dry eye syndrome and evaluate the relationship with
quality of life in the office workers in Eskişehir Osmangazi University Faculty
of Medicine. This is a cross-sectional study conducted between January-April
2017 in Eskişehir Osmangazi University Faculty of Medicine. The study group
consists of 317 office workers who are employees of Faculty of Medicine. The
existence and level of dry eye syndrome was evaluated with The “Ocular Surface
Disease Index“ (OSDI) and SF-36 quality of life scale were used to evaluate
health-related quality of life. The people who scored 13 or more in OSDI scale
were accepted as having dry eye syndrome. Of the employees, 89 (28.1%) were
male and 228 (71.9%) were female. The ages ranged from 22 to 63 years, with a
mean of 35.86 ± 8.11 years. The prevalence of dry eye syndrome was found as
77.6% (n = 246). The prevalence of dry eye syndrome was found to be higher in
women, in patients with clinically diagnosed chronic disease, in
continuous-drug use, and in the group having another diagnosed eye disease. The
mean scores of all sub-scales of SF-36 quality of life scale were lower in
patients with dry eye syndrome. (For each sub-scale p≤0.05). There was a weak
negative correlation between the scores obtained from the OSDI scale and the
scores obtained from all subfields of the SF-36 scale. Dry eye syndrome is an
important health problem and the quality
of life was found to be worse in people with this syndrome. It is recommended
office workers has to be informed about disease for the prevention and about
the correct use of displays. The screening of the office workers for the early
diagnosis of the disease and directing the identified cases to the specialist
physicians are also important.

Çalışmada, Eskişehir Osmangazi
Üniversitesi Tıp Fakültesi hastanesi ve dekanlığında görev yapan büro
çalışanlarında Kuru Göz Sendromu (KGS) sıklığının saptanması, ilişkili olduğu
düşünülen bazı faktörlerin incelenmesi ve yaşam kalitesinin değerlendirilmesi
amaçlandı. Bu çalışma, Ocak-Nisan 2017 yılında Eskişehir Osmangazi Üniversitesi
Tıp Fakültesi Dekanlığı ve Sağlık, Uygulama ve Araştırma Hastanesi’nde görev
yapan büro çalışanları arasında gerçekleştirilen kesitsel tipte bir
araştırmadır. Çalışmaya katılmayı kabul eden 317 kişi çalışma grubunu
oluşturdu. KGS varlığı ve şiddetinin değerlendirilmesinde Oküler Yüzey Hastalık
İndeksi ölçeği (OSDİ), sağlıkla ilişkili yaşam kalitesinin değerlendirilmesinde
SF-36 yaşam kalitesi ölçeği kullanıldı. OSDİ ölçeğinden 13 ve üzeri puan
alanlarda KGS olduğu kabul edildi. Çalışanların
89’u (%28.1) erkek, 228’i (%71.9) ise kadındır. Yaşları 22-63 arasında
değişmekte olup, ortalaması 35,86 ± 8,11 yıl idi. Araştırmamızda büro çalışanlarında
KGS görülme sıklığı %77.6 (n=246) olarak saptandı. Kadınlarda, hekim tanılı
kronik hastalığı olanlarda, sürekli ilaç kullananlarda ve hekim tanılı başka
bir göz hastalığı olanlarda KGS sıklığının daha yüksek olduğu saptandı. KGS
olanlarda SF-36 yaşam kalitesi ölçeğinin bütün alt alanlarından alınan puan
ortalamaları daha düşük idi. (Her alt alan için p≤0.05). OSDİ ölçeğinden alınan
puanlar ile SF-36 ölçeğinin tüm alt alanlarından alınan puanlar arasında
negatif yönde zayıf bir korelasyon saptandı. Büro çalışanlarında KGS önemli bir
sağlık sorunu olduğu ve bu sendromun saptandığı kişilerde yaşam kalitesinin
daha kötü olduğu görüldü. KGS’den korunma hususunda hastalık ile ilgili
farkındalık ve ekranlı araçların doğru kullanımı ile ilgili bilgilendirme
etkinliklerinin düzenlenmesi, hastalığın erken teşhisi için taramaların
yapılması ve saptanan olguların uzman hekimlere yönlendirilmesi önerilmektedir.
