Purpose: To evaluate the reproducibility of a new colour test, using the Chromatometer CM3. Methods: Twenty healthy subjects were recruited at the Department of Ophthalmology, at the Medical University of Vienna. A total of 40 eyes were tested. Both eyes were tested separately with the Chromatometer CM3. The colour test was repeated after several days. Each time, best-corrected visual acuity was tested using Snellen charts, and colour perception was tested using the Chromatometer CM3. Results: The Chromatometer CM3 showed reproducible results between the two tests at almost every luminosity level. All 4 green-red measurements and 2 blue-yellow brightness measurements showed reproducible results between the first and second tests. Conclusion: The Chromatometer CM3 seems to be an appropriate method to detect changes in colour perception, although the red-green comparison appeared to be more precise than the blue-yellow comparison.
