Abstract
Purpose: This study was to find the correlation between exophthalmetry and visual functions. Methods: Exophthalmetry and visual functions of 200 adults without ophthalmophathy and general disease were examined. Exophthalmetry were measured with Hertel's exophthalmometer. Visual functions (myopia, distance exophoria, near exophoria, near point of convergence, near point of accommodation) were measured for three times. Results: The exophthalmetry was $13.59{\pm}1.10mm$. Myopia, distance exophoria, near exophoria, near point convergence, and near point accommodation were measured as $-2.48{\pm}1.91D$, $3.51{\pm}1.78{\Delta}$, $5.73{\pm}2.44{\Delta}$, $9.63{\pm}2.82cm$, and $21.73{\pm}10.28cm$. With increasing exophthalmetry, the unaided visual acuity, myopia and astigmatism were decreased. On the other hand, distance exophoria, distance esophoria, near exophoria, near point of convergence and near point of accommodation were significantly increased, while exophthalmetry was increased. Conclusions: The relationship between visual functions and exophthalmetry were found to be statistically significant. It could be used as the clinical criteria for prescription of binocular inspections.
목적: 안구돌출도와 시기능의 상관관계를 알아보고자 하였다. 방법: 안질환과 전신질환이 없는 성인 남녀 200명(20~50대 각 50명)을 대상으로 안구돌출도와 시기능을 검사하였다. 허텔 안구돌출계로 안구돌출도를 측정하였고, 근시, 외사위, 내사위, 폭주 근점, 조절 근점 등 시기능 요소에 대한 검사를 3회 반복하여 실시하였다. 결과: 안구돌출도는 $13.59{\pm}1.10mm$, 근시, 원거리 외사위, 근거리 외사위, 폭주 근점 그리고 조절 근점은 $-2.48{\pm}1.91D$, $3.51{\pm}1.78{\Delta}$, $5.73{\pm}2.44{\Delta}$, $9.63{\pm}2.82cm$, $21.73{\pm}10.28cm$로 나타났다. 안구돌출도가 증가할수록 나안시력, 근시 그리고 난시도는 유의하게 감소하였다. 반면 원거리 외사위, 원거리 내사위, 근거리 외사위, 폭주 근점 그리고 조절 근점은 안구돌출도가 증가할수록 유의하게 증가하였다. 결론: 시기능과 안구돌출도의 유의한 관계는 양안시 처방과 검사를 위한 임상적 기준이 될 수 있을 것으로 사료된다.
