OCT is a tool by which highly magnified photographs of the retina can be taken to study it's microscopic structure. The patient has to just sit in front of a machine for a few minutes and look at a particular light while these special images are acquired. It also helps to measure the retinal thickness in microns. So the doctor can determine if the retina is getting thicker or thinner. Also which layers of the retina are getting more affected can be evaluated and the response to treatment can be judged by serial examinations.
Very informative article. Thanks!
