Color vision defects, particularly blue-yellow type, are common in older adults and increase with age. The Adams and Farnsworth D-15 tests showed good agreement in identifying these age-related vision changes.
Area of Science:
- Ophthalmology
- Gerontology
- Vision Science
Background:
- Age-related changes in vision are common.
- Color vision can be affected by aging.
Purpose of the Study:
- Determine the frequency and types of color vision defects in older adults.
- Evaluate the agreement between the Adams desaturated D-15 and Farnsworth D-15 tests.
Main Methods:
- 865 individuals aged 58-102 years were tested.
- Adams desaturated D-15 and Farnsworth D-15 tests were administered.
- Color defect types were classified using Vingrys and King-Smith (1988) method.
Main Results:
- Failure rates were 36.2% for Adams D-15 and 20.76% for Farnsworth D-15.
- Failure rates increased with age for both tests.
- Blue-yellow defects were the most common type observed.
Conclusions:
- Blue-yellow defects are prevalent in the aging population.
- Both D-15 tests demonstrated high agreement in identifying red-green and blue-yellow defects.
- The Adams D-15 identified more defects, but defect types were similar between tests.
