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. Clinical Applications 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 Clinical Benefits 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 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
