| Summary: |
Purpose: In
patients with lacrimal drainage system obstruction, the
inflammation and fibrosis may be secondary to coexisting
infectious colonization within the lacrimal sac. It is
possible that many cases of acquired nasolacrimal duct
obstruction are in fact secondary to unrecognized
low-grade dacryocystitis. The intent of this study was
to determine what organism grow in the lacrimal sac of
patients required dacrocystorhinostomy (DCR). It also
investigated correlation between organism cultured from
the lacrimal sac and the nose.
Material and Methods: The study included 20
patients (16 women and 4 men) with unilateral epiphora
undergoing endoscopic DCR. Samples were obtained
intraoperatively from the lacrimal sac near the sac-duct
junction and from the nose. Microbiologic analysis was
carried out to determine the presence and identification
of organisms.
Results: Positive culture results from lacrimal
sac were obtained in 80%. The majority of microorganisms
in our study were Gramm-positive bacteria, accounting
for 87.5% the overall isolates with a predominance of
Staphylococcus aureus (56.2%) and Staphylococcus
epidermidis (25%). Gramm-negative bacteria were present
in 18.7% of the specimens. In 45% of patients the same
microorganisms were cultured from the two studied sites.
Conclusion: The presence of a positive culture
results is independent of a history of dacryocystitis.
Nasolacrimal duct obstruction in adults is associated
with an increased proportion of Gramm-negative organisms
in rate to physiological bacterial flora. There is not a
clinically significant correlation between bacterial
flora of the lacrimal sac and the nose. |
