Why Color Vision?

Color vision begins with the cone cells and is supported by all layers of the visual pathway. Damage to any of these layers affects color vision. Research has shown color vision to be a biomarker of all major eye diseases, even those which are slow progressing in which the patient is unaware of any change in color perception.

Color vision occurs early in eye disease and continues to decline as the disease progresses. Unlike most other functional measures, which demonstrate abnormality only if areas of the retina have died, color vision can detect changes from sick or compromised cells. This sensitivity allows for the earliest detection of disease and its progression as well as functional improvement from therapies. Research has shown the Rabin Cone Contrast Test to be one of the earliest indicators of both early and progressive change from disease.”

Combining Structural and Functional Testing

Combining structural and functional testing can provide a more complete insight into severity and progression over using structural tests alone. Sensitive functional tests are able to identify sub-clinical changes in disease that are not yet detectable on structural tests. While structural tests are very specific, functional tests are more sensitive.

Using these forms of testing together provides more complete information about the disease and its progression.

The Rabin Cone Contrast Test™ detects the earliest changes, allowing for earlier intervention, and resultingly, changing the course of disease.

Allows for early detection of:

  • AMD

  • Glaucoma

  • Diabetic Eye Disease

  • High-Risk Medication Toxicity

  • Neurological Conditions

Rabin Cone Contrast for Early Detection

Using the Rabin Cone Contrast is as important in AMD and diabetes as using a visual field in glaucoma. If you wait for structural changes, you may have missed decades of progression. With 50% of patients with eye disease going undiagnosed, if you’re not using the Rabin CCT, you may be missing a lot of eye disease.
