Abstract

Schirmer test is one of the most used methods for the diagnosis of dry eye. We attempted to develop a tear level measurement tool to replace unreliable Schirmer test with inaccurate results. Absorbency tests for various absorbents were carried out. As a result, ${\alpha}$ cellulose pulp was selected as the absorbent. Prototypes were produced and evaluated twice. Finally a tear level measurement tool in the form of a strip of ${\alpha}$ cellulose pulp adhered to a polyurethane was prepared. Usability evaluation of prepared tear level measurement tool was performed. As a result, it was confirmed that it has a significant correlation with SM tube developed oversea recently. In addition, it was judged to be useful as an alternative to the Schirmer test in terms of measurement time and accuracy.

건성안 진단에 있어서 가장 많이 사용되는 방법 중 하나이나, 부정확한 결과로 신뢰도가 떨어지는 쉬르머 검사법을 대체할 수 있는 눈물양 측정 도구를 개발하고자 하였다. 이를 위해 다양한 흡수제에 대한 흡수성 시험을 통하여 알파 셀룰로즈 펄프를 흡수제로 선택하였다. 2차례에 걸쳐 시제품을 제작하여 평가하였으며, 최종적으로 알파 셀룰로즈 펄프를 폴리우레탄에 접착한 스트립 형태의 눈물양 측정 도구를 제작하여 사용성 평가를 실시하였다. 그 결과 해외에서 최근에 개발된 눈물양 측정 도구인 Strip Meniscometry와 유의한 상관성을 갖는 것을 확인할 수 있었으며, 측정시간 및 측정의 정확성 측면에서 쉬르머 검사법의 대체 검사법으로 유효한 것으로 판단되었다.
