Medical Discovery News, Sept. 6, 2008 Saturday's edition of Medical Discovery News, by UTMB professors Norbert Herzog and David Niesel, was about two new eye tests being developed that can detect Alzheimer's disease. "They involve a low-intensity laser that briefly sends low-power light into the eye. It's safe and not uncomfortable.  In one test, a device detects any scattering of the light which would happen if small clumps of beta amyloid are present. In the second test a fluorescent dye is injected into the eye to bind to the proteins. When you shine an infrared light, they glow confirming Alzheimer's disease." Medical Discovery News airs at 10 a.m. on KUHF-FM in Houston. The program also airs on numerous radio stations across the country and in Mexico.
