목적 : 컴퓨터 환경에 맞게 새로 개발된 SNU 전산화 색각검사로 선천색각이상자의 분류 및 특징을 알아보고자 하였다. 대상과 방법 : 정상인, 색각이상자 각30명 60안을 대상으로 이시하라검사, Hardy-Rand-Rittler 검사(HRR 검사), Nagel 색각경검사, 그리고 SNU 전산화색각검사를 시행하였다. 결과 : SNU 전산화색각검사상 정상인은 모든 색깔에서 오점수는 0으로 나왔다. 색각이상자 중 제 1 색각이상에서는 오점수 최고치는 색상번호 0 적색에서 7안(29.2%), 색상번호 150 녹색에서 3안(12.5%), 색상번호 180 녹색에서 18안(75%), 색상번호 330 적색에서 2안(8.3%)이었다. 제 2 색각이상에서는 오점수의 최고치는 색상번호 0 적색에서 2안(5.6%), 색상번호 150 녹색에서 24안(66.7%), 색상번호 180 녹색에서 2안(5.6%), 색상번호 330 적색에서 23안(63.9%)이었다. 결론 : 선천색각이상자는 컴퓨터 환경에서 전산화된 검사인 SNU전산화색각검사에서 특별한 부분에 축을 나타내었고 색각이상의 진단에 있어서 높은 민감도와 분류의 정확성을 보여주었다. 향후 이를 이용하면 편리하고 빠르게 색각이상을 진단하고 분류하는데 임상에서 유용하게 사용될 수 있을 것으로 기대된다.

Purpose: This study was designed to investigate the characteristics and classification of congenital color vision deficiency (CVD) by the SNU computerized color test (SCCT) that was developed to sufficiently utilize the advantages of a computer. Methods: Hardy-Rand-Rittler test (HRR test), Nagel anomaloscope and SCCT were performed on 60 eyes of 30 CVD patients and 30 normal subjects and the results were compared. Results: In normal subjects, the error scores were all zero at all colors by SCCT. By SCCT protan color defectives showed a peak at hue 0 red in 7 eyes (29.2%), at hue 150 green in 3 eyes (12.5%), at hue 180 green in 18 eyes (75%), and at hue 330 red in 2 eyes (8.3%). By SCCT, deutan color defectives showed a peak at hue 0 red in 2 eyes (5.6%), at hue 150 green in 24 eyes (66.7%), at hue 180 green in 2 eyes (5.6%), and at hue 330 red in 23 eyes (63.9%). Conclusions: SCCT showed specific axes in CVD patients, with accuracy and high sensitivity to diagnosis. SCCT appears to be useful clinically as a color vision test to diagnose and classify CVD patients.
