Abstract

The present paper reviews the adverse side effects caused by topically applied antiviral agents in herpetic keratitis. The effective treatment of herpetic keratitis with IDU, a chemotherapeutic agent, was first reported in 1962.

The therapy often continued for months or in some cases, even more than one year. Numerous reports on its side effects have appeared. The side effects can be classified into two categories. The first category is allergic contact blepharodermatitis, a type IV delayed hypersensitivity reaction. Its occurrence is difficult to foresee. This category I side effect rarely results in the destruction of the ocular tissues. The second category of side effects is a drug-induced toxic side effect resulting in punctate epithelial keratitis, papillary conjunctivitis or follicular hypertrophy and lacrimal punctal obstruction. After withdrawal of IDU, these ill effects usually subside soon. When IDU is further continued, the destructive change of the tissues will ensue. Conjunctival cicatrization, symblepharon, corneal neovascularization, cicatrization...Continue Reading
