Objectives: The purpose of this study is to find out whether ocular dominance has any effect on tear functions in unilateral pinguecula; and whether these tests differ within the patients. Methods: 63 men and 57 women participated to the study. The groups were: Pinguecula on dominant eye and pinguecula on non-dominant eye. Hole-in-the-card test was used to determine the dominant eye. Patients underwent detailed ophthalmic examination followed by tear Break up Time (BUT), Schirmer test and Ocular Surface Disease Index Questionnaire (OSDI). Mann-Whitney U test and Wilcoxon signed rank test was used for comparisons between and within groups. A value of P < 0.05 was considered statistically significant. Results: Within the dominant eye group, normal and pinguecula eye BUT and schirmer results were statistically insignificant (p=0.08 and p=0.506). In Non-dominant eye group, normal and pinguecula eye BUT and schirmer results were also statistically insignificant (p=0.58 and p=0.16). The difference between OSDI scores of the Dominant and Non-dominant eye group was insignificant (p=0.579). Between the dominant and non-dominant eye groups, BUT were not statistically different in the eyes with pinguecula (p=0.45) and eyes without pinguecula (p=0.36). Also, between these groups, Schirmer results were not statistically different in the eyes with pinguecula (p=0.36) and eyes without pinguecula (p=0.27). Discussion: Unilateral pinguecula does not cause tear function changes between normal and pinguecula present eyes; and ocular dominance has no effect on tear functions in unilateral pinguecula patients. This is the first study to investigate whether ocular dominance affects tear functions in pinguecula.

Amaç: Bu çalışmanın amacı, tek taraflı pingekulada oküler baskınlığın gözyaşı fonksiyonlarına etkisinin olup olmadığını ve bu testlerin hastalar arasında farklılık gösterip göstermediğinin araştırılmasıdır. Gereç ve Yöntem: Hastalar (63 erkek, 57 kadın) iki gruba bölündü: dominant gözünde pingekula olanlar ve non-dominant gözde pingekulası olanlar. Dominant gözü belirlemek için kartta delik testi kullanıldı. Hastalara detaylı göz muayenesi ile gözyaşı kırılma zamanı (BUT), Schirmer testi ve Oküler Yüzey Hastalık İndeksi Anketi (OSDI) yapıldı. Gruplar arası ve grup içi karşılaştırmalarda Mann-Whitney U testi ve Wilcoxon testi kullanıldı. P < 0.05 değeri istatistiksel olarak anlamlı kabul edildi. Bulgular: Dominant göz grubu içinde normal ve pingekulalı göz BUT ve schirmer sonuçları istatistiksel olarak anlamlı değildi (p=0.08 ve p=0.506). Dominant olmayan göz grubunda normal ve pingekulalı göz BUT ve schirmer sonuçları da istatistiksel olarak anlamlı değildi (p=0.58 ve p=0.16). Dominant ve non-dominant göz grubunun OSDI puanları arasındaki fark istatistiksel olarak anlamlı bulunmadı (p=0.579). BUT; Dominant ve non-dominant göz grupları arasında pingekulalı gözlerde (p=0.45) ve pingekula olmayan gözlerde istatistiksel olarak farklı değildi. Ayrıca bu gruplar arasında, pingekulalı gözlerde ve pingekula olmayan gözlerde Schirmer sonuçları istatistiksel olarak farklı değildi (sırasıyla p=0.36 ve p=0.27). Tartışma: Tek taraflı pingekulası olan hastalarda, normal göze kıyasla gözyaşı fonksiyonunda ve OSDI testinde farklılık izlenmemiştir. Aynı zamanda pingekulanın dominant göz veya non-dominant gözde olmasının aynı testlerde bir etkinliğinin olmadığı izlenmiştir. Bu çalışma pingekulada oküler baskınlığı gözyaşı fonksiyonlarına etikini araştıran ilk çalışmadır.
