Benefits of technology

The invention is a system and process for testing and monitoring diseases affecting the eye, which includes a test called Cone Contrast Test (CCT) to measure color perception. This test is efficient, fast, and low-cost and can be used to detect potential diseases or toxicity. The duration between calibrating the test can be adjusted based on testing policies and procedures. The calibration is automatically performed at predetermined intervals, which helps to ensure the accuracy of the test results.

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.
