COLOR-VISION IN GYRATE ATROPHY

A follow-up study of colour vision in two patients with gyrate atrophy was performed. Gyrate atrophy was diagnosed in the first patient at t he age of 17 years. Her colour vision was first tested at the age of 2 5 years; at the follow-up examination 7 years later, she correctly int erpreted the Standard Pseudoisochromatic Plates part 2, however, with one mistake due to lens opacity. In the Farnsworth-Munsell 100 hue tes t and in the Color Vision Meter 712 (CVM) anomaloscope, the results we re within normal ranges. In the second patient, gyrate atrophy was dia gnosed at the age of 4 years. At the ages of 4 and 5 years, he correct ly interpreted the Ishihara, AO H-R-R, and Lanthony Tritan Album plate s as well as the City University test. At the ages of 6, 7, and 8 year s, he correctly interpreted the plate tests, the Farnsworth Panel D 15 , and Lanthony's Desaturated Panel. The CVM anomaloscope results were normal.
