Evaluation of the Waggoner Computerized Color Vision Test

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• Traditional color vision tests have remained largely unchanged for decades.
• Computerized color vision tests offer advantages but lack widespread adoption.
• The Waggoner Computerized Color Vision Test (CCVT) was developed for accessibility on standard computer systems.

Purpose of the Study:

• To evaluate the Waggoner Computerized Color Vision Test (CCVT) for clinical use.
• To assess the CCVT's performance in screening and diagnosing color vision deficiency (CVD).

Main Methods:

• Tested 59 subjects with CVD and 361 without on the CCVT, anomaloscope, Richmond HRR, and Ishihara.
• Administered the CCVT using default settings and a standardized Correlated Color Temperature (CCT) of 6500 K.
• Determined sensitivity, specificity, and correct classification rates for the CCVT.

Main Results:

• The CCVT demonstrated high screening performance with 95% sensitivity and 100% specificity.
• CCVT classified deutan or protan deficiencies in 89% agreement with anomaloscopy.
• CCVT results were consistent across default and calibrated CCT settings for most subjects, with some discrepancies noted.

Conclusions:

• The Waggoner CCVT is a suitable color vision screening tool with notable advantages.
• The CCVT provides a reasonably accurate diagnosis of color vision deficiency type.
• The CCVT can be a valuable addition to existing color vision test batteries when used adjunctively.
