Summary
This study establishes age-corrected normal values for visual field testing using the Tübingen Automatic Perimeter. Peripheral visual field sensitivity declines more with age than central sensitivity.
Area of Science:
- Ophthalmology
- Visual Neuroscience
Context:
- Accurate assessment of visual field defects, particularly early glaucoma, necessitates age-corrected perimetric values.
- Establishing normative data is crucial for detecting subtle changes in light sensitivity.
Purpose:
- To determine age-corrected normal values for visual field testing using the Tübingen Automatic Perimeter.
- To compare age-related changes in central versus peripheral visual field sensitivity.
Summary:
- Eighty-five healthy subjects aged 18-70 underwent visual field testing with the Tübingen Automatic Perimeter 2000cc.
- Age-related normal values were calculated, revealing a significantly smaller decline in central (0.5 dB) compared to peripheral (4-6.5 dB) visual field sensitivity between ages 20 and 70.
Impact:
- Provides essential age-corrected normative data for the Tübingen Automatic Perimeter.
- Highlights differential age-related decline in visual field sensitivity, aiding in the detection of early glaucomatous changes.
