Purpose: To detect tear function abnormalities in patients with pterygium.
Methods: 33 eyes of 24 patients with pterygium were evaluated for Schirmer I test, corneal tear film break up time (BUT) and tear meniscus height (TMH); results were compared with the other eyes in unilateral cases and with 40 eyes of 20 age and sex-matched control patients separately. The results were analyzed with analysis of variance and parametric tests.
Results: There was no significant difference in age, sex distribution and systemic status of the patients between study and control groups (p=0.24). Mean Schirmer I test value was 10.3±1.8 (Mean±SEM) in patients with pterygium and 18.7±3.1 in control group (p=0.01). Mean BUT was 9.1±1.5 seconds in patients with pterygium and 10.0±1.3 seconds in control group (p=0.48). TMH was more than 0.1 mm in 90% of the cases in both group (p=0.95).
Comment: The changes in Schirmer I test in patients with pterygium indicates that these patients have a decreased total tear secretion compared to normal population.Keywords: Pterygium, dry eye, tear function testsTurkiye Klinikleri J Ophthalmol 2000, 9:1-3
