Abstract
Dry eye is a widely common disease in Egypt. Tear film stability and tear secretion are important factors in the assessment of Dry eye disease. Schirmer test is used to assess tear secretion. TBUT is used to assess tear film stability.Subjects and methods The study included 150 normal healthy subjects. Subjects were divided into different groups according to age, sex, residency and occupation. History was taken from all subjects including ocular surface disease index questionnaire. All subjects undergo full ophthalmological examination, Schirmer test and TBUT.Results The mean ST for the population sample was 21.9 ± 9.13 mm. The mean TBUT for the population sample was 16.04 ± 4.99 seconds. Studying linear regression for Schirmer test with age, sex, occupation and residency showed that Schirmer test was mostly affected by age where it showed positive correlation. Studying linear regression for TBUT with age, sex, occupation and residency showed that TBUT was mostly affected by residency.Conclusion The study allowed us to get a picture of the normative data of Schirmer test and TBUT and the effect of different variables on both tests
