ColorDx -Model CCT HD -High-Precision Diagnostic Color Vision Testing
Color vision and contrast sensitivity are important functions of the visual system, which may be affected by many diseases, disorders and common drugs and substances. Understanding if and how much visual function is affected may assist clinical decision making and augment conversations with your patients.
- FDA Listed - CPT Code 92283
- CE Marked
- TGA Approved
- Available in Canada
The new gold standard in diagnostic color vision testing
Assess visual function beyond high-contrast acuity
Developed in collaboration with the U.S. Air Force School of Aerospace Medicine OBVA (Operational Based Vision Assessment) laboratory under CRADA, CCT HD expands on the strengths of the original USAF cone-isolation contrast test (Rabin CCT) and is built from the ground up with entirely new architecture.
Highlights include:
- Cone-isolation contrast sensitivity methodology
- Expanded low-contrast range testing
- “Landolt C” based test strategies
- Simple to use 4-button response pad
- Robust Bayesian threshold with standard error
- Konan custom-calibrated IPS matte display technology
- Rapid, intuitive, staged calibration
- High fidelity cone-contrast granularity
- Expansive illustrated reporting
- Auto trends analysis
- Contrast Sensitivity (achromatic) with auto AUC calculation
- …and much more
1 in 5 may have a color vision deficiency. Contemporary eye care includes qualitative and quantitative assessment of this important measure of visual function.
Acquired color deficiencies are commonly S-cone (blue-yellow) type, but may also affect L- and M-cones.
Acquired deficiencies are typically gender neutral and become more common with age, yet may affect up to 15%* of the general population.
This important but often overlooked clinical sign may be caused by retinal, macular, optic nerve, trauma or neurological disorders, in addition to cataracts and high-risk meds, as well as hundreds of common drugs and substances**.
Testing for acquired color vision deficiencies may be one of the most underutilized measures of functional vision. Commonly used color vision tests historically (such as printed pseudo-isochromatic, “Ishihara plates”, designed more than a century ago), may only test L and M-cone deficiencies, completely missing all S-cone (blue) deficiencies as well as being not quantitative. Genetic color vision deficiencies, most commonly affect males as a sex-linked trait and most commonly affect the L or M-cones.
- DR, glaucoma, AMD, MS
- Other disorders of the retina or optic nerve
- Pre and post cataract surgery
- Vocational, avocational, and scholastic color vision testing
- Track the effect of supplements over time2
- ColorDx is not cleared for the specific diagnosis of any condition
- Detect subtle changes missed by books, plates, and other color vision tests
- Compare structure & function, especially when subjective SAP does not correlate with OCT
- Inform patients about the risks, consequences and hazards related to deficiencies in their cone and achromatic contrast sensitivity
