근시성 굴절부등에 대한 임상적 고찰 = A Clinical Study on Relation among Accommodative Amplitude, Response, and Facility in young adults

다국어 초록 (Multilingual Abstract)

Purpose: This study has been conducted to know the prevalence of anisometropia and corneal refraction, accommodative response of myopic anisometropia. Methods: The study subject were 67 persons who myopic anisometropia of at least 1.00D, from among 808 total subject without ophthalmic diseases history from age 5 to 89 and the test were used to examine with both eyes open-view autorefractometer (NvisionK-5001). Results: The case which anisometropia were 85(10.5%) persons and myopic anisometropia were 67(78.8%) persons among the anisometropia. Difference between higher myopic eye and lower myopic eye were -1.22D.94 in spherical equivalent, -0.25D.72 in accommodative response, 0.04D.68 in corneal refraction. In addition, the same case of both eyes accommodative response were 33(49.3%) persons, the great case of lower myopic eye accommo- dative response were 25(37.3%) persons and the great case of higher myopic eye accommodative response were 9(13.4%) persons. Conclusions: Myopic anisometropia was not affected by corneal refraction and both eyes difference of spherical equivalent was less as compared with both eyes difference of accommodative response.

목적: 굴절부등의 발생률과 근시성 굴절부등의 양안 조절반응량, 각막굴절력 등을 알아보았다. 방법: 안질환이 없 는 5세에서 89세의 남녀 808명 중 양안 근시성 굴절부등이 1.00D이상인 67명을 대상으로 하였으며, 양안개방형 자 동굴절검사기(Nvision K-5001)를 이용해 검사를 실시하였다. 결과: 굴절부등이 있는 경우는 85명(10.5%)이였고, 그 중 67명(78.8%)이 근시성 굴절부등으로 나타났다. 근시성 굴절부등의 굴절이상이 강한 쪽과 약한 쪽으로 분리하여 양안 차이를 비교해 본 결과 등가구면굴절력은 -1.22D.94로, 조절반응량은 -0.25D.72로, 각막굴절력은 0.04D.68로 나타났다. 또한 양안의 조절반응량이 같은 경우가 33명(49.3%), 근시가 약한 쪽이 많은 경우가 25명 (37.3%), 근시가 강한 쪽이 많은 경우가 9명(13.4%)으로 나타났다. 결론: 근시성 굴절부등은 각막굴절력에 영향을 받지 않았으며, 양안 등가구면굴절력 차이에 비해 조절반응량의 차이가 적었다.
