2. Rabin Cone Contrast Test by Innova Systems
15 Years of US Air Force research
Published, Peer Reviewed
Validated against Anomaloscope
Innova Approved as Sole Color Vision Test for US Air Force
Over 400 in Use Worldwide

3. Rabin Cone Contrast Test
by Innova Systems
Colored letters stimulate single cone type / pathway
Decreasing contrast steps detects cone function threshold
Numeric scores provide Hereditary vs. Acquired discrimination
Change over time metric

4. Color Normal vs. Deficient
A Color Vision Test Sensitive Enough to Detect Severity of Cone Deficiency
Used to Detect and Monitor Acquired Color Deficiency
AMD
Glaucoma
Diabetic Retinopathy MS
Parkinson’s Disease
TBI
Retinal Toxicity due to High Risks meds such as Plaquenil
Color Normal
vs.
Deficient

6. BLUE CONE LOSS
Acquired blue cone loss occurs early in eye disease, sometimes before visual field defect(s)
Very few blue cones: small amount of damage has large effect
Secondary to disease, trauma or toxicity
Often asymmetric

10. Current Research Military - Cases of Optic Neuropathy
Identified with RCCT that was missed by all other equipment.
Cone recovery shown with RCCT.
Military – Central Serous Retinopathy
Military – Traumatic Brain Injury
Identified with RCCT
Duke University – Dry AMD
Clinical Trial results: the AREDS 3 intermediate AMD group exhibited visual dysfunction on the Rabin Cone Contrast Test, in the presence of normal visual acuity
New clinical trial begins fall 2014
Other: Diabetes , MS, Plaquenil, Alzheimers, Glaucoma, Macular Pigment Density Loss

11. Improved Quality of Care
Patient Benefit Simultaneous Hereditary + Acquired Color Vision Evaluation
Identification of patients at-risk for developing disease.
Earlier recognition and intervention of disease.
Rapid detection of disease progression.
Evaluation of treatment efficacy.
Improved Quality of Care
