Rabin Cone Contrast Test (RCCT)

Rabin Cone Contrast Test (RCCT)

A More Detailed Look at Your Color Vision
The Rabin Cone Contrast Test (RCCT) is a specialized vision test that measures how well your eyes detect the colors red, green, and blue. Unlike traditional color vision tests that simply check whether you can identify certain colors, the RCCT measures how sensitive your eyes are to each color.

This test provides a more detailed picture of your color vision and can help identify color vision deficiencies, as well as changes in vision that may be associated with certain eye conditions.

What to Expect During the Test
The RCCT is a computer-based test that uses colored letters or symbols displayed on a calibrated monitor.

Why Is This Test Performed?
The RCCT may be recommended for several reasons, including:

Aviation and occupational screening
The test may be used to help evaluate color vision for aviation medical certification and certain military or occupational requirements. It can be particularly helpful for individuals who do not pass a standard color vision screening test.

Monitoring eye health
Changes in color vision can sometimes be associated with changes in the health of the retina or optic nerve. The RCCT can help assess and monitor color vision in people with certain eye conditions, including:

• Age-related macular degeneration (AMD)

• Glaucoma

• Diabetic retinopathy

• Retinal changes associated with certain medications, including hydroxychloroquine (Plaquenil)
