Abstract

Purpose: Stereopsis is one of primary characteristics for assessment of binocular function. The purpose of this study was to determine the possible relationship between the degree of exophoria and stereoacuity at near. Methods: 110 exophores (male n=71, female n=39, mean $age{\pm}SD=11.30{\pm}1.47$ years) without amblyopia, strabismus, and ocular and systemic pathology were studied. Subjects were also excluded if they had visual acuity poorer than 0.8 in either eye or vertical phoria greater than 1 prism diopter. Clinical tests were performed for near phorias by von Graefe technique using a Digital Refractor (CDR-3100, Huvitz, Korea) with chart (Predio CDC-4000, Huvitz, Korea), and for stereoacuity using the Titmus fly. Results: A one-way analysis of variance revealed that mean values of the stereoacuity classified according to the degrees of the exophoria were not significantly different (p>0.05). Conclusions: Based on the result of this study, it was found that there was no relationship between the degree of exophoria and stereoacuity.

목적: 입체시는 양안시 기능을 평가하는 중요한 기준의 하나이다. 이 연구에서는 근거리에서 외사위의 정도와 입체시의 관계를 확인해 보고자 한다. 방법: 사시나 약시 및 안질환이나 전신질환이 없고 근거리 단안 시력이 모두 0.8 이상이면서 수직사위가 1 프리즘 디옵터 미만인 110명(남자 71명, 여자 39명, 평균 나이 $11.30{\pm}1.47$세)의 외사위안을 대상으로 하였다. 근거리의 사위는 디지털 검안기(CDR-3100, Huvitz, Korea)와 디지털 챠트(Predio CDC-4000, Huvitz, Korea)를 사용하여 Von Graefe 기법으로 측정하였고, 근거리의 입체시는 Titmus fly를 사용하여 측정하였다. 결과: 외사위의 정도에 따라 분류한 입체시의 평균에 대해 일원배치분산분석을 실시한 결과 유의한 차이가 없는 것으로 나타났다(p>0.05). 결론: 이 연구의 결과를 통해 외사위의 정도와 입체시는 관련성이 없음을 확인하였다.
