AIM:To evaluate the performance of dominant eye(DE) for color vision discrimination ability among the medical students with normal color ***:Total of 50 students studying at Baskent University Faculty of Medicine,including 31 males(62%) and 19 females(38%),with visual acuity of 20/20 and without congenital color vision deficiency(CCVD) evaluated by Ishihara pseudoisochromatic plate test(IPPT) were recruited for this prospective comparative study upon their voluntary *** was determined by the Gündogan *** color discrimination ability was examined with the FarnsworthMunsell 100 hue(FM100) *** was applied by two days interval to all subjects for the three times while two eyes(TE),right eye(RE) and left eye(LE) were seeing for detecting red-green(r/g),blue-yellow(b/y) local color spectral regions error *** error scores were evaluated for both in DE and non-dominant(NDE).P values below 0.05 were considered to be statistically ***:The students aged 21.18±2.52 years(mean±SD).Without sex difference the RE and the LE dominancy were found 22(44%) and 28(56%) respectively and FM 100 test total error scores of DE in both r/g-b/y regions were found without gender difference 24.12±14.70,34.68±18.95,*** the NDE in both,r/gb/y regions error scores without gender difference were 32.20±19.21,36.24±17.56,*** difference of total error scores between the DE and NDE was found as 58.80±29.92,68.44±*** statistical differences among the DE and the NDE in r/g local region and total error scores were found significant in both genders(P<0.05,P<0.001). CONCLUSION:The color vision discrimination performance ability was found prominent for *** superiority was attributed to higher sensitivity of the r/g local color spectral *** conclude that DE has priority in r/g color spectral region,probably including inhibition of NDE.
