Cogan Syndrome
Diagnosis of Cogan Syndrome
An eye examination The diagnosis of Cogan syndrome is suspected when a person has symptoms of corneal inflammation without any known cause. A Slit-Lamp Examination , an instrument that enables a doctor to examine the eye under high magnification, is usually used to examine the cornea. Blood tests for syphilis, Lyme disease, and the Epstein-Barr virus are done to rule out these diseases, which may have symptoms similar to those of Cogan syndrome. Computed tomography (CT) or magnetic resonance imaging (MRI) is done.
