한국인의 양안 시기능 이상에 관한 고찰

Prevalence of binocular anomalies in adult Koreans

한국인 성인 남자 41명, 여자 60명을 대상으로 굴절이상과 양안시 이상을 검사한 결과 근방 수평사위 46%, 근방내전 이상 52.5%, 근방외전 이상 55.5%, AC/C(Accommodative convergence/Accommodation)이상 50.4%, PRA (Positive relative accommodation) 이상 61.4%, NRA(Negative relative accommodation) 이상 54.5%를 차지했다. 또한 양안 시기능검사 결과를 모간 분석에 의해 분석한 결과 폭주이상 21.7%, 조절이상 29.7%, 조절과 폭주이상 34.6%로 나타났다.

To describe the prevalence of binocular anomalies in adult Koreans. Patients included were 19 to 40 years of age, 41 males and 60 females and living in Kwang-Ju Korea. Refractive correction was estimated objectively with an autorefractometer and subjectively refined without cycloplegia. Myopia was defined as a refractive error less than -0.50 diopters hyperopia was defined as a refractive error greater than +0.50 diopters. 101 no strabismic patients who had a refractive error and a near lateral phoria(46%) and an AC/A(accommodative convergence/accommodation) anomaly(50.4%). The prevalence of a near vergence anomaly(52.5%) was higher than a near divergence anomaly(55.5%). The prevalence of a positive relative accommodation(PRA) anomaly(61.4%) was higher than a negative relative accommodation(NRA) anomaly(54.5%). According to Morgan's analysis method, patients with vergence anomaly(21.7%) were seen slightly less frequently than those with accommodative interaction anomaly(29.7%). 34.6% of patients had both vergence anomaly and accommodative interaction anomaly. These results indicate that full prescription for a refractive corrections should be considered as these can improve binocular visual function for ametropia.
