title: Herpetic canalicular obstruction.
abstract: The viruses of primary herpes simplex, herpes zoster, chicken pox, and vaccinia may produce inflammatory changes in the epithelial lining of the lacrimal canaliculi, resulting in varying degrees of obstruction. Five cases are described and compared with previously reported cases. A review of the literature suggests that the association of ocular viral infections and canalicular complications may be more prevalent than previously suspected. The possible important role of antiviral agents is considered. Early recognition and intubation can often prevent permanent canalicular obstruction, but late cases may require the Jones tube procedure, conjunctivodacryocystorhinostomy.
