title: [Morphological characteristics of actinomycotic dacryocanaliculitis].
abstract: The paper presents the results of pathohistological studies of the contents of the lacrimal canaliculi and the fragments of their walls, obtained at canaliculotomy in 25 patients. This permitted 14 cases of actinomycotic dacryocanaliculitis to be identified as drusens of the ray fungus Actinomyces israelii had been found. The reactive structural changes found in the wall of the lacrimal canaliculi due to the presence of fungal infection and foreign bodies in their lumen are described. A morphological study is shown to be effective in revealing the actinomycotic etiology of dacryocanaliculitis.
