A method for quantitative scoring of the Farnsworth Panel D-15

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• The Farnsworth Dichotomous test (Panel D-15) is a standard qualitative tool for assessing color vision defects.
• Current scoring relies on diagrammatic representation of hue confusions, limiting quantitative analysis.
• Understanding color vision defects is crucial for diagnosing and managing various visual impairments.

Purpose of the Study:

• To introduce a novel quantitative scoring system for the Panel D-15 test.
• To enable objective measurement of color vision defect severity based on hue confusions.
• To facilitate the correlation of Panel D-15 results with other visual functions and experimental conditions.

Main Methods:

• Development of a quantitative scoring algorithm based on hue confusion patterns from the Panel D-15.
• Application of the new scoring technique to existing clinical data.
• Analysis of the quantitative scores to assess color vision defect type and severity.

Main Results:

• The proposed quantitative scoring provides an objective measure of color vision impairment.
• The scoring method effectively categorizes the type and severity of hue confusions.
• Illustrative clinical examples demonstrate the utility of the quantitative score.

Conclusions:

• The new quantitative scoring method enhances the diagnostic value of the Panel D-15 test.
• Objective quantification allows for more robust research and clinical applications.
• This approach offers a more precise assessment of color vision deficits.
