[Representation of normal and pathologic macular color vision]

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• The computerized chromatic test offers a novel approach to visualizing color perception.
• It aids in differentiating between normal and pathological retinal color processing.

Purpose of the Study:

• To introduce and evaluate a computerized chromatic test for assessing color vision.
• To demonstrate the test's utility in identifying color vision defects.

Main Methods:

• The test utilizes an album of six series of plates with varying saturation levels, a lamp, and a computer program.
• Graphic representation of perceived colors is generated by the computer.

Main Results:

• Normal eyes display a chart with concentric saturation levels, with the most saturated circles externally located.
• Dyschromatopsia (acquired or congenital) shows a central neutral zone, indicating the limits of color perception.

Conclusions:

• The computerized chromatic test is a user-friendly tool for assessing color vision.
• It effectively visualizes and helps appreciate color vision defects.
