Abstract

Purpose: To compare the dry eye prevalence between McMonnies and Ocular Surface Disease Index questionnaires for twenties university students and to find out the difference between them. Methods: We distributed the McMonnies/OSDI questionnaire to 1157 students of 10 university and investigate whether they had dry eye symptoms. After classified each results by severity, we compared the prevalence of dry eye between each questionnaires. Then, we found the optimal cut-off points that the most similar results revealed between them with kappa coefficients. Result: When cut-off point was 14.5 point, the prevalence of McMonnies was 7.1%, but OSDI was 41.6% when 23.5 point and the similarity between them were significantly low (k=0.292, p<0.001). The optimal pair of cut-off points revealed the most similar results between them were McMonnies 7.5 point which excluded 3 disease questions and OSDI 22.5 point. Each prevalence at those cut-off point were 39.4% and 41.6%, respectively (k=0.794, p<0.001). Conclusion: The results illustrated that prevalent different of McMonnies and OSDI questionnaires were significant. The Optimal pair of cut-off points were McMonnies 7.5 point which excluded 3 disease questions and OSDI 22.5 point. In those cut-off points, the prevalence of McMonnies was 2.2% higher than that of OSDI.

목 적: 20대 대학생을 대상으로 McMonnies 및 Ocular Surface Disease Index(ODSI) 건성안 설문지를 이용한 건성안 유병률을 비교하고 그 차이를 확인하고자 하였다. 방 법: 전국 10개 대학교 안경광학과에 재학 중인 대학생 1,157명을 대상으로 McMonnies 및 OSDI(Ocular Surface Diseease Index) 설문지를 이용하여 건성안 정도를 조사하였다. 증상의 정도를 정량화하여 두 설문지의 유병률을 비교한 후 카파 계수(kappa coefficient)를 활용하여 유병률 일치도가 가장 높은 분류기준점을 찾고자 하였다. 결 과: McMonnies설문은 기준점이 14.5점 기준일 때 유병률이 7.1%였고 OSDI설문은 23.5점 기준일 때 41.6%였으며 일치도(kappa coefficient)는 매우 낮았다(k=0.292, p<0.001). 일치도가 가장 높은 최적의 조합은 OSDI 설문의 22.5점과 McMonnies 설문 중 질환 관련 세 가지 문항을 제외한 9문항의 설문에 대하여 7.5점을 기준으로 분류한 결과이었고, 유병률은 각각 OSDI 41.6%, McMonnies 39.4%였다(k=0.794, p<0.001). 결 론: 설문지를 활용하여 건성안을 판별할 경우 McMonnies 및 OSDI설문의 유병률이 큰 차이를 보였다. 두 설문의 일치도가 가장 높은 판별 절단점의 조합은 McMonnies 7.5점 및 OSDI 22.5점이었으며 이 절단점에서의 유병률은 McMonnies설문이 OSDI설문보다 약 2.2% 더 높았다.
