Summary
Arden grating test scores increase with age in normal subjects, a finding not previously reported. New age-specific normal value ranges are recommended for this visual assessment.
Area of Science:
- Ophthalmology
- Visual Science
- Gerontology
Background:
- The Arden grating test assesses visual function.
- Established ranges for interocular conguity exist but may not account for age-related changes.
Purpose of the Study:
- To evaluate Arden grating test scores in a normal population.
- To investigate the influence of age on Arden grating test performance.
Main Methods:
- 100 normal subjects underwent standardized Arden grating testing.
- Data analysis focused on correlating test scores with subject age.
Main Results:
- Previously published interocular conguity ranges were confirmed.
- A significant positive correlation between age and Arden grating test scores was observed.
- This age-related increase in scores is a novel finding.
Conclusions:
- Age significantly impacts Arden grating test scores.
- Existing normal value ranges may require age stratification.
- Establishing age-specific normal ranges is recommended for accurate clinical interpretation.
