Abstract

Binocular vision had a short history in Korea. As there were many near works in these days, the needs about comparative study have been increased. There was related to both refractive error and binocular anomalies, but it is difficult to applying for binocular vision expected findings in itself due to the fact that Korean differ from foreigner. Objects were 100 adults in 18-36 years old ages, The test was Von Gaefe method and used aparatus was phoropter(Shinnippon VT10)and visual chart(Shinnippon CT30). According to interview results was that symptom in near works were headaches 28.0%, blinking 27.3%, red eye 25.1%, eyepain 15.6%, watering 15.3%, itch 12.2%, photophobia 8.5% and eye strain 7.4%. A people who have above ${\pm}0.50$ D refractive error in total objectives (100-male 45/female 55) were classified into ametropia. There was a results such as emmetropia (12.0%), ametropia(88.0%), exophoria(32.0%), esophoria(12.0%). Far negative relative convergence were that in case of high 43.0%, in case of low 7.0%. Far positive relative convergence were that in case of high 15.0%, in case of low 38.0%. Near phoria was exophoria(32.0%), esophoria(12.0%). Near negative relative convergence were that in case of high 23.0%, in case of low 38.0%. Far positive relative convergence were that in case of high 29.0%, in case of low 23.0%. Near negative relative accommodation were that in case of high 10.0%, in case of low 14,0%, Far positive relative convergence were that in case of high 69.0%, in case of low 12.0%. Results were different from expected findings, and especially positive relative accommodation was very high, However, We suggest that the expected findings in Korea for several subjects must study in binocular function.

양안시가 국내에서 연구되기 시작한 역사는 길지 않지만 근업이 많아지면서 비교연구의 필요성이 대두되고 있다. 양안시기능 이상은 굴절이상과 관계가 있으나 외국과 한국은 비정시 분포가 서로 다르므로 한국인의 양안시기능 값을 검사하여 기대값과 비교하였다. 검사대상은 안질환이 없는 만 18세에서 36세까지의 성인남녀 100명에 대해 문진을 실시하고, 양안 완전교정 후 균형을 취한 상태에서 시기능검사(Von Graefe method)를 실시하였고, 기기는 phoropter(Shinnippon VT10)와 visual chart(Shinnippon CT30)를 사용하였다. 검사대상자의 근업시 안정피로도는 두통(28.0%), 잦은 눈깜박임(17.3%), 충혈(15.1%), 안통(10.6%), 유루(10.3%), 쓰림(10.2%), 수명(4.5%), 안구통증(4.0%)의 순으로 나타났으며 검사대상자 총 100(남 45명/여 55명)명 중 ${\geq}{\pm}0.50$ D의 굴절이상을 가진 자를 비정시로 분류하였는데, 그 중 정시안은 12명(12.0%)이고, 비정시자는 88명(88.0%)이었으며, 원방수평사위는 외사위가 32.0%, 내사위가 12.0%로 나타났으며, 원방 허성상대폭주력은 기대값보다 높은 경우가 43명(43.0%), 낮은 경우가 7명(7.0%)이었으며, 원방 실성상대폭주력의 경우 기대값보다 높은 경우가 15명(15.0%)이고, 낮은 경우가 38명(38.0%)이었다. 근방수평사위는 외사위가 48.0%, 내사위가 20.0%로 나타났으며, 근방 허성상대폭주력은 기대값보다 높은 경우가 23명(23.0%), 낮은 경우가 38명(38.0%)이었으며, 근방 실성상대폭주력의 경우 기대값보다 높은 경우가 29명(29.0%)이고, 낮은 경우가 23명(23.0%)이었다. 근방 허성상대조절력은 기대값보다 높은 경우가 10명(10.0%), 낮은 경우가 14명(14.0%)이었으며, 근방 실성상대조절력의 경우 기대값보다 높은 경우가 69명(69.0%)이고, 낮은 경우가 12명(12.0%)이었다. 결과값은 기대값과 다소 차이를 보였으며 특히 실성상대조절력이 현저하게 높게 나타났으며, 향후 많은 대상자에 의한 한국인 기대값을 제정하는 것이 과제라고 사료된다.
