Extract

The International Colour Vision Society awarded the 2003 Verriest Medal to André Roth, Honorary Professor of Ophthalmology at the University of Geneva. This award is bestowed by the Society to honor long-term contributions to the field of color vision. André Roth created the Roth 28 Hue test for ophthalmological examination, and developed and standardized a sophisticated diagnostic set of tests based on color metrics for acquired color vision deficiencies. He developed an anomaloscope specially for the investigation of acquired and inherited color vision deficiencies in ophthalmology. As director of the Geneva University clinic, he has studied most eye diseases in which acquired color deficiencies play a significant role. Work for the IRGCVD and later ICVS was a significant part of his professional life. Together with Guy Verriest (the first President of the Society, for whom the medal is named), André belonged to the clinically oriented group, which recommended a separation of the IRGCVD from the AIC, to give ophthalmologists, physiologists and other clinicians a scientific home and a connection to color science. Soon after the death of Guy Verriest he took over the presidency of the Society from Wolfgang Jaeger and carefully led its further development, with expanded emphasis of genetic, molecular biological, physiological, and psychophysical research.
