목적 : 정상청년인구에서 상대구심성동공운동장애의 빈도를 알아보고, 그 경우 반대편 눈과 비교하여 어떤 차이가 있는지 알아보고자 하였다. 방법 : 시력검사, 안압 측정, 굴절검사, 세극등검사, 안저검사에서 굴절이상 외 정상 소견을 보이는 14~36세 58명에서 손전등과 동공도검사기기를 이용하여 교대불빛검사를 시행하였다. 상대구심성동공운동장애가 발견되는 경우 색각검사, optical coherence tomography, Humphrey 시야검사, Bryngelson test (hole-in-the-card test)를 하였다. 결과 : 58명 중 1명에서 손전등과 동공도검사 기기에서 우안의 상대구심성동공운동장애를 확인하였다. 우안의 근시성 난시가 더 심하고 Humphrey 시야검사의 평균편위가 좌안보다 감소되었으나 두 눈 모두 정상범위였으며 우안이 우세안이었다. 결론 : 정상청년인구에서 상대구심성동공운동장애의 빈도는 1.7%로서 굴절이상이 더 심한 눈에서 상대구심성동공운동애가 발견되었다.

Purpose: In order to investigate the incidence of relative afferent pupillary defect (RAPD) in normal adolescence and if there is any interocular difference in the case with RAPD. Methods: Fifty-eight adolescence in 14 to 36 years of age who showed normal findings on measurement of visual acuity, intraocular pressure, slit lamp examination, and funduscopic examination except refractive errors underwent swinging flashlight test and infrared pupillography. The case with RAPD further underwent optical coherence tomography, color vision test, Humphrey visual field test, and Bryngelson test (hole-in-the-card test). Results: One out of 58 cases, in whom more pronounced myopic astigmatism and lower mean deviation on Humphrey visual field test within normal limits were found, showed RAPD in the dominant right eye with swinging flashlight test and infrared pupillography. Conclusions: The incidence of RAPD in normal adolescence was 1.7%. Myopic astigmatism was higher in the eye with RAPD.
