Summary

This study followed two patients with gyrate atrophy, finding their color vision remained normal despite the condition. Comprehensive testing showed no significant deficits in color perception over time.

Background:

Gyrate atrophy is a rare inherited eye disease causing progressive vision loss.
Understanding its impact on color vision is crucial for patient management.

Observation:

Two patients diagnosed with gyrate atrophy underwent serial color vision testing.
Testing included standard pseudoisochromatic plates, Farnsworth-Munsell 100 hue test, Color Vision Meter 712 (CVM) anomaloscope, Ishihara, AO H-R-R, Lanthony Tritan Album, City University test, and Farnsworth Panel D 15.

Findings:

The first patient, diagnosed at 17, showed normal results on most tests at 25 and 32, with a minor error attributed to lens opacity.
The second patient, diagnosed at 4, maintained normal color vision across multiple tests from ages 4 to 8.

Implications:

Gyrate atrophy may not significantly impair color vision in affected individuals.
Continued monitoring of color vision is recommended for patients with gyrate atrophy.
