What is cytomegalovirus retinitis?
Cytomegalovirus is a member of the herpes virus family and almost all adults are silently infected with this virus during childhood when infection with this virus does not cause any symptoms. Cytomegalovirus is reactivated in the very late stages of AIDS and can attack a number of organs. The eye is vulnerable to cytomegalovirus, specifically the retina, the layer of special light-detecting cells at the back of the eye.
