[Actinomycetes canaliculitis--case reports].

Canaliculitis is a relatively rare dacryocanal infection which occurs most unilateral. It can easily be misinterpreted and not sufficiently treated. Typical agents of the canaliculitis are actinomyces, that can cause infections of the hollow spaces with formation of concrements. The clinical courses of two patients are shown. One of them was treated for a dacryocystitis for 3 years and the other one had been referred to the eye hospital for chalazion removal. Only a microbiologic examination including cultivation of the surgically obtained dacryolithes and secretion enabled us to a reliable proof of the actinomyces and to an appropriate therapy for canaliculitis.
