| Abstract |
|
Several tests have been used for assessing color vision but most of them are nonspecific, expensive, complicated or too time consuming to perform. We have developed a new computerized color vision test named Seohan computerized 85-hue test[SCHT/85]that has many advantages compared to Farnsworth Munsell[FM]100-hue test.SCHT/85 has 85 color caps which can be displayed based on a model of FM 100-hue test using Multimedia toolbook 4.0.Selected color caps in the lower random area can be moved and inserted to the upper result area by a mouse.At the end of the test, error scores and ring graph can be displayed in monitor and can be also printed out. Total 15 subjects performed with SCHT/85 and FM 100-hue test twice who have been showed 10 normal and 5 abnormal color vision reported with other color vision tests and the results of two tests were analysed to compare the total error scores[TES]and reproducibility. All ten normal subjects showed lower TES in SCHT/85 than FM 100-hue test and the mean TES were 31.5 and 43.6 with SCHT/85 and FM 100-hue test.The coefficients of variation [CV]were 4.3%and 22.7%with SCHT/85 and FM 100-hue test.The two tests were highly correlated[r=0.92].Five abnormal subjects showed higher TES in SCHT/85 than FM 100-hue test and the mean TES were 169.8 and 157.3 with SCHT/85 and FM 100-hue test.The coefficients of variation were 9.1%and 21.2%with SCHT/85 and FM 100-hue test.These two tests were also highly correlated[r=0.965]. In conclusion, SCHT/85 which was newly developed by authors is a highly useful test for color vision. |
