Abstract

We examined refractive error, the corrected visual acuity, phoria and fusional reserve of 114 healthy myopes and hyperopia who had no strabismus, no ocular and physical diseases. We evaluated the occurrence of asthenopia according to phoria and fusional reserve. 41 out of 114 subjects which exophoria was 69% and esophoria was 5.5%, orthophoria was 26% made a complaint against asthenopia. The subjects who had exophoria of $0-6{\Delta}$ in the range of normal state was 61.4%, while the subjects who had exophoria of $7{\Delta}$ or more in the range of abnormal state was 38.6%. Reducing fusional reserve was associated with increasing phoria. The fusional reserve twice or more than phoria were 27.2%, and twice or under were 72.8%. Futhermore, AC/A ratio for heterophoria was found from 1.0 to 12.6 and its relationship to asthenopia of phoria could not be determined.

전라북도 지역에 거주하는 성인들의 안위특성과 안정피로의 연관성을 조사하였다. 사시, 안질환 또는 전신질환이 없는 19세에서 55세까지의 비정시안 114명을 대상으로, 교정시력, 안경교정 굴절력, 융합여력검사, 사위검사를 실시하였으며, 사위방향 및 크기와 융합여력에 따른 안정피로 발생 빈도를 분석하였다. 114명 가운데 41명이 안정피로를 호소하였고 이 가운데 외사위는 69%, 내사위는 5.5%, 정위는 26% 였다. 근거리 측정에서 정상으로 간주되는 $0-6{\Delta}$의 외사위은 61.4%이었고, 정상범위 외의 사위는 대상안의 38.6%이었다. 융합여력의 크기는 사위량이 많을수록 적어졌으며, 융합여력이 사위량의 2배 이상인 사람이 27.2%이고 2배 미만인 사람이 72.8%로 조사되었다. Heterphoria 방법으로 측정한 AC/A는 최저 1.0에서 최대 12.6까지 분포하고 있었으며, 사위안의 안정피로와는 특별한 관계를 발견 할 수 없었다. 사위에서 유발되는 안정피로가 융합여력과 연관성이 있었으며, 사위안의 근거리 안경 교정을 위한 양안시 검사를 수행할 때 융합여력 검사를 수행해야 할 것으로 생각된다.
