| eye infections, viral | Infections of the eye caused by minute intracellular agents. These infections may lead to severe inflammation in various parts of the eye - conjunctiva, iris, eyelids, etc. Several viruses have been identified as the causative agents. Among these are herpes virus, adenovirus, poxvirus, and myxovirus. (12 Dec 1998) |
