    The New Color Test (NCT) generally aligns with other color vision tests, but lacks precise correlation with AOH-R-R classification. Increased sensitivity is observed across different tests, suggesting redundancy when the 8/2 panel test is normal.

    Area of Science:

    • Ophthalmology
    • Color Vision Science

    Background:

    • Accurate color vision assessment is crucial for diagnosing various visual impairments.
    • Standardized tests like the AOH-R-R, D-15, and New Color Test (NCT) are used for evaluating color perception.
    • Understanding the comparative performance and correlations between these tests is essential for clinical application.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy and inter-test correlations of the New Color Test (NCT) against established color vision tests.
    • To determine the sensitivity progression across different color vision assessment tools.

    Main Methods:

    • Comparative analysis of classification results from AOH-R-R, panel D-15, NCT 6/2, and a desaturated panel 8/2.
    • Assessment of the correlation between the AOH-R-R classification and the NCT classification.

    Main Results:

    • The general statements in the NCT manual were confirmed.
    • No exact correlationship was found between the AOH-R-R classification and the NCT classification.
    • A gradual increase in sensitivity was observed from AOH-R-R to D-15, NCT 6/2, and finally the 8/2 panel.
    • The NCT 6/2 provides no additional information if the 8/2 panel test result is normal.

    Conclusions:

    • While the NCT is generally consistent with other tests, its classification does not precisely correlate with AOH-R-R.
    • The 8/2 panel test demonstrates higher sensitivity, potentially making the NCT 6/2 redundant in cases of normal 8/2 results.
    • Clinical utility of NCT may depend on specific diagnostic needs and comparison with other sensitive tests.
