목적: 본 연구는 임상에서 건성안의 진단 및 눈물막의 평가 방법으로 많이 사용되고 있는 Tear Film Break-up Time(BUT) 검사를 통해 BUT의 평균값을 알아보고 콘택트렌즈 착용자와 비 착용자와의 값을 비교 하였다. 방법: 대상자는 눈물의 분비량에 영향을 미칠 수 있는 안과적 질환을 동반하지 않은 20~40대까지의 성인남녀 155명(310안)을 대상으로 BUT값을 측정하였다. 결과: BUT 평균치는 남성이 12.585±3.999초, 여성은 9.761±3.339를 나타냈으며, 콘택트렌즈 착용자와 미 착용자의 BUT는 콘택트렌즈 착용자가 10.516±3.244초, 콘택트렌즈 미 착용자가 12.198±4.158초로 나타났다(p

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.
