Rabin Cone Contrast Test, Andalusia, AL
Early Detection of Eye Disease Through Color Vision Testing
At Ensight Eyecare, we are excited to offer the Rabin Cone Contrast Test™ in Andalusia, Alabama. This cutting-edge diagnostic tool uses patented cone contrast technology to precisely measure color vision loss and provide a more complete understanding of disease progression.
Many common eye conditions, including glaucoma, diabetic eye disease, age-related macular degeneration (AMD), and medication-related toxicity, can start to damage your vision long before you notice any symptoms. By measuring how well your eyes detect red, green, and blue colors, the Rabin color vision test helps us catch changes that traditional eye exams or imaging may miss, allowing for earlier treatment.
What is the Rabin Cone Contrast Test™?
The Rabin Cone Contrast Test™ (CCT) is a fast, non-invasive test that takes just 2–3 minutes per eye. It uses precisely calibrated, colored letters that fade in contrast to test each of the three cone types independently. This allows our eye doctors to quantify color vision loss, and pinpoint which cones are affected.
Cone cells are responsible for color vision. When they’re not functioning properly, it can be an early sign of eye disease. The Rabin Cone Contrast Test™ is one of the earliest ways to identify these changes, allowing us to begin treatment before permanent vision loss occurs. The Rabin color test can help us with detecting several eye diseases and issues:
Early AMD Detection
Research from Duke University shows that color vision loss often precedes visible changes in AMD. The Rabin cone test can detect both early-stage dry AMD and subtle changes in intermediate AMD, even before they’re visible on optical coherence tomography (OCT) scans.
Glaucoma Screening
By the time glaucoma is detectable via standard visual field tests, significant retinal damage has often occurred. Cone contrast testing can reveal early color vision changes that may be linked to glaucoma, giving us a chance to act sooner and protect your vision.
Diabetic Eye Exams
Diabetes can affect the eyes long before you notice vision problems. One of the earliest signs is often a loss of color vision, even before blood vessels in the eye show changes. Adding the Rabin cone test to your diabetic eye exam helps us detect issues early and tailor your care to prevent serious complications.
Plaquenil Monitoring
If you take Plaquenil (Hydroxychloroquine) for autoimmune conditions, regular comprehensive eye exams are essential to assess for early signs of retinal toxicity. In the early stages, most people don’t notice any vision problems and standard vision tests often appear normal. However, your color vision can be affected early on. The Rabin Cone Contrast Test™ can spot early signs of retinal toxicity before other tests detect a problem.
Cataract Evaluation
As cataracts yellow the lens, they disproportionately affect blue cone perception. The Rabin cone test can help us distinguish between cataract-related vision changes and those caused by retinal disease, guiding both diagnosis and treatment decisions.
