title: Colour vision in gyrate atrophy.
abstract: A follow-up study of colour vision in two patients with gyrate atrophy was performed. Gyrate atrophy was diagnosed in the first patient at the age of 17 years. Her colour vision was first tested at the age of 25 years; at the follow-up examination 7 years later, she correctly interpreted the Standard Pseudoisochromatic Plates part 2, however, with one mistake due to lens opacity. In the Farnsworth-Munsell 100 hue test and in the Color Vision Meter 712 (CVM) anomaloscope, the results were within normal ranges. In the second patient, gyrate atrophy was diagnosed at the age of 4 years. At the ages of 4 and 5 years, he correctly interpreted the Ishihara, AO H-R-R, and Lanthony Tritan Album plates as well as the City University test. At the ages of 6, 7, and 8 years, he correctly interpreted the plate tests, the Farnsworth Panel D 15, and Lanthony's Desaturated Panel. The CVM anomaloscope results were normal.
