[Chronic suppurative canaliculitis - clinical and therapeutic aspects: report of 3 cases].

Lacrimal canaliculitis is a rare disease caused mainly by Actinomyces israelii. It should be regarded as a differential diagnosis of recurrent chronic conjunctivitis. The purpose of this study was to report 3 cases of chronic suppurative canaliculitis and different treatment options. The first patient presented with an upper left canaliculitis and was treated with a canaliculotomy. Nevertheless, he had an ipsilateral lower canaliculitis after 6 months and underwent intracanalicular injections of fortified cefazolin with complete remission. The second patient presented with a lower left canaliculitis and underwent a canaliculotomy. The third patient had a lower left canaliculitis and underwent intracanalicular injections of fortified cefazolin. Both achieved complete remission. The present article demonstrated that intracanalicular irrigation of fortified cefazolin may be a helpful treatment of chronic suppurative canaliculitis with mild symptoms and signs. The most important benefit of this approach is to avoid injury to the lacrimal canaliculus.
