| Abstract |
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. |
