Abstract Details

Purpose:

To investigate the relationship between OSDI (Ocular Surface Disease Index), the Schirmer test, and tear break up time (BUT) measurements in patients with pterygium and compare this according to pterygium grades.

Setting:

The BUT measurements and the Schirmer tests were evaluated in patients with pterygium, and OSDI questionnaires were applied.

Methods:

OSDI scores were calculated, and the patients were grouped according to their OSDI scores. The Pterygium grades were also determined, and the Anova test was used to investigate the relationship between the OSDI scores and the Schirmer tests/BUT measurements, and between the OSDI scores and pterygium grades.

Results:

Fifty-two pterygium patients were included and grouped according to their OSDI scores in this study. The difference between the BUT and Schirmer results were statistically significant between Group 1 and Group 2 (p=0.02, p=0.01, respectively). Also, the BUT measurement differences between Group 1 and Group 3 were significant (p=0.02). The OSDI scores were found to be higher in the Grade 3 pterygiums than in the Grade 1 pterygiums. When we considered pterygium grades, BUT was negatively correlated to OSDI (p=0.022), whereas Schirmer was not correlated with OSDI (p=0.325).

Conclusions:

Most of the pterygium patients showed ocular discomfort signs according to their OSDI scores. BUT measurements are correlated with pterygium grades, whereas Schirmer test results did not correlate with the pterygium grades.
