Evaluation of the City University Colour Vision Test

Anne Fitzgerald, DipAppSci in Ortho (Cumb), DOBA

The use of the City University Colour Vision Test for routine screening for colour vision abnormalities is evaluated. The results of screening for colour vision abnormalities using the City University Test are compared to results obtained when the patients are tested with the Ishihara test and Farnsworth Munsell Panel D 15 test. All patients in the study were also tested on the Farnsworth Munsell 100 Hue Test to confirm the presence and severity of the colour vision defect. The City University Test was found to be the most reliable of the three screening tests used in this study for detecting congenital and acquired red green and /or blue yellow defects however it appears to be of limited value in testing patients with optic nerve disease.
