Benefits of technology

The invention is a method and device for testing and monitoring progress and treatment of eye diseases that affect the whole body or the nervous system. This is done using a Cone Contrast Test (CCT) which measures color perception by different types of cone cells in the eye. The results of the test are compared to a standard score to assess disease or toxicity levels. The device allows for frequent calibration to ensure accurate results. This invention is efficient, cost-effective, and easy to use for screening potential diseases or toxic effects on the eye.

Problems solved by technology

Additionally, a low cost calibration system is needed due to inconsistent calibration over time.
With standard “off-the-shelf” colormeters, interference from other software, including software produced by Microsoft Corporation, override calibration values and render the test invalid.

Abstract

A method and apparatus for administering eye tests to identify cone sensitivity loss associated with hereditary and acquired color vision loss which may be used for early detection, progress, treatment, and monitoring of eye conditions, traumatic brain injury, optic neuritis, systemic and neurological diseases including Glaucoma, Retinopathy, Age-Related Macular Degeneration, Multiple Sclerosis, Alzheimer's Disease, and Parkinson's Disease and retinal toxicity. Particularly, the method and apparatus disclosed uses a Cone Contrast Test (CCT) to test individuals for hereditary or acquired color vision loss associated with (a) early signs of potential disease / damage / toxicity in an effort to (i) provide opportunity for treatment, and (ii) prevent permanent eye damage, and (b) monitor progress and treatment of such disease / damage / toxicity. The system comprises a computer system including an input device and a display device, and the accuracy and repeatability of the testing is provided by repeated calibration using a colormeter.
