Soon aft(prenominal) the test, doctors will know if the child can look at and how easily it can percolate. The examination single-valued function, which involves measuring brain wheel military action prompted by optic stimuli (also called visual evoked potentials or VEPs) has been amend by Drs. Barry Skarf of the Department of Ophthalmology and Moshe Eizenman of U of Ts Institute Their procedure is much(prenominal) accurate than tests used elsewhere because Eizenman has highly-developed a novel, real-time computer program to extract brain wave responses from extremely small patterns (similar in size to the bottom cable system of a standard eye test) which produce much more reliable results. Until now, doctors would have to extrapolate the babys ability to see small stimuli from test results using large stimuli. In Effect, Dr. Eizenman has developed a way of looking at brain waves that is more sensitive than methods previously available, says Skarf.

At the HSC, VEPs are used in a number of clinical applications: to determine whether a visual problem is cognitive; to assess whether babies who dont appear to see well will see better in the prospective; to determine a course of treatment for such problems in which one eye turns in or is weaker than the other eye. The moment aspect of the researchers work involves the development of a stimulator for stereopsis, or binocular vision, which is the fusing of images from both eyes into one picture that has depth. The problem with testing binocular vision, ... If you want to get a full essay, narrate it on our website: Ordercustompaper.com
