The Study of Chronic Dacryocystitis: Identification of Pathogenic Organism and Histopathological Findings

ABSTRACT

The study of chronic dacryocystitis Identification of pathogenic organism and histopathological findings. Primary acquired nasolacrimal duct obstruction is a clinical syndrome of unknown cause, and the histopathology of the nasolacrimal duct has not been substantially studied. The intent of this study was to determine what organisms grow in the lacrimal sac of patients ewquirirng dacryocystorhinostomy. It was also investigated whether or not there was a correlation between organisms cultured from the sac and from the conjunctiva. The tissue fo lacrimal sac was examined histopathologically. A total of 32 patients who had received dacryyocystorhinostomy from January 1998 to July 1998 were included. The result of the study indicate thath there is not a clinically significant correlation of pathogenic organism between conjunctiva and lacrimal sac. Most patients had histopathologic findings consisted of inflammation or fibrosis of the lacrimal sac. The incidence of significant pathology of the lacrimal sac is low. However, one case was identified as an adenocarcinoma by routine biopsy of the lacrimal sac during dacryocystorhinostomy.
