Purpose : In this study. we analyzed reliabilitis of Schirmer test and Tear Film Break up Timet(BUT) which are generally used in the diagnosis of dry eyes. Furthermore, this study was carried out to prepare the valuatien of diagnosis and standard in the clinic. Methods : 130 adults at the age range of 20s-40s who don't have eye disease which can have an impact on the amount of tear were tested by method of Schirmer test and Tear Film Break up Time(tBUT) teat and we analyzed the values. Results : The standard deviation of Schirmer test and Tear Film Break up Time(tBUT) were found to be the 12.083±4.7141 mm and the 10.848±4.7458. The Chronbach's alpha value for the reliability Schirmer test was 0.431. which is a bit low. This value is implying that the reproducibility is low. too. However. the value of Tear Film Break up Time(tBUT) is 0.918, which is high. It means the reproducibility is high, too. Conclusion : We judged that Schrimer test values to assess te<Jr voln mP. showeci low reliability. Therefore. this test can not be used in getting materia! for diagnosis of dry eyes independently. In case of quality of tear film assess. Tear Film Break up Time(tBUT) test is a useful method because of high reliability.
