한국인에 대한 누액 안정성 조사

The stability of tear film for Korean

건안은 콘택트렌즈를 착용하는 대부분의 환자에게서 쉽게 나타날 수 있으며 방치해 두면 누액의 안정성이 줄어들고 누액의 찌꺼기, 점액이 점점 증가하면서 각막 얼룩이 형성되어 눈에 충혈, 건조감 등을 동반할 수 있다. 본 연구에서는 51명의 성인 남녀를 대상으로 건성안을 판단하기 위해 Schirmer test, TBUT, 순목 횟수 등을 조사하였다. 건성안 검사 방법 중 순목 횟수는 1분에 평균 19회였고 Schirmer test의 평균은 5분에 25mm이였으며, TBUT는 평균 7.1초로 나타났다. 이런 결과로 TBUT 검사치가 낮으면 순목 횟수가 증가하는 것으로 나타났다.

The purpose of our study was stability of tear film for Korean. In the 1970s, the major problem for the contact lens practitioner was the management of contact lens parameters. In the 1980s, oxygen permeability was the main problem in contact lens practice: now it is dry eyes. To appropriately fit the patient with contact lenses it is imperative to know in advance if the patient has a marginal dry eye. Based on the initial diagnosis appropriate care can be taken to minimize problems with the result that the patient can successfully wear contact lenses. A well known test for dry eyes is Schirmer test which has shown to be useful for diagnosing Sjogren syndrome. Biomicroscopy can often unmask numerous problems. The classical test for marginal dry eye is measuring the tear break up time(TBUT). A dry eye problem with contact lenses is often caused by the lid. If an incomplete blink is responsible for the dry eye it is possible to change the situation by blinking exercises. The result of these test, mean value of age was 22.8, mean value of blink rate was 19 times/min, mean value of Schirmer test was 25 mm/5 min, mean value of TBUT was 7.1 sec.
