Optical diagnostic

An optical diagnostic was a type of medical diagnostic that focused on the eye. 
In 2368, after Geordi La Forge came into sickbay with symptoms of an ear infection, including dizziness, Dr. Beverly Crusher, on a hunch, ran an optical diagnostic which traced the problem to his VISOR, which was causing a phase shift in his visual receptors. The condition made him see images, or as he described them, "blurry after-images", that weren't really there. Crusher then ran a scan to detect what he was seeing, and was able to pick up minuscule distortions in the surrounding dekyon field, distortions which the VISOR translated into visual impulses. ()
