초록

본 연구의 목적은 전북지역 성인들의 사위와 융합여력의 특성을 알아보자 하였다. 사시안, 안질환이 없는 20세에서 44세까지의 근시안을 가진 성인 116명을 대상으로 교정시력, 교정굴절력, 사위검사, 융합여력검사를 실시하였다. 프리즘분리법에 의한 수평사위검사에서 정위(26.7%) 외사위 (52.5%),내사위(20.7%)명이었다. 38.8%는 근거리에서 정상으로 간주되는 0-6${\Delta}$의 외사위를 가지고 있었고, 61.2%는 정상범위를 벗어난 사위를 가지고 있었다. 융합여력의 크기는 사위량이 많을수록 적어졌다. 사위안의 융합여력이 안정피로에 연관성이 있음을 알 수 있었고, 사위 처방시 융합여력을 검사하여야 할 것으로 생각된다. 또한 그래디앤트법으로 AC/A비를 측정한 결과 4.03이었으며, 굴절 이상과는 특별한 관계를 발견할 수 없었다.

The aim of this study was to evaluate the property of heterophoria and fusional reserve in Adults in Jeon-buk Area. We examined the corrected visual acuity, corrected refractive error, heterophoria and fusional reserve of 116 healthy myopes aged from 20 to 44 old who had no strabismus no ocular and phyisical diseases. Using Von Graefe test of horizontal heterophoria Measurement, we measured orthophoria(26.7%), exophoria(52.5%) and esophoria(20.7%) for at near distance. The subjects who had exophoria of 0-6${\Delta}$ in the range of normal state was 38.8%, while the subjects who had exophoria in the range of abnormal state was 61.2%. Reducing fusional reserve was associated with increasing phoria. We found a relationship between asthenopia and fusional reserve of heterophoria and considered that fusional reserve must be examined when we preserve for a patient with heterophoria. Furthermore, Gradient method AC/A ratio was found 4.03 and its relationship to refractive error could not be determined.
