ABSTRACT
ContextLacrimal drainage system obstruction gives discomfort to patients and threatens intraocular surgeries by infection, thus, knowledge of its bacteriology leads to the choice of effective therapy.Aim:
To determine the bacteriology of nasolacrimal duct obstruction in an adult Libyan patient population and to analyze the appropriate antimicrobial therapy based on susceptibility testing.Settings andDesign:
A prospective study was conducted at the Great River Eye hospital, Benghazi/Libya in the period between September 2005 and February 2007.Methods:
Lacrimal swab materials collected from patients aged 1862 years who were diagnosed as having lacrimal passage obstruction and referred for lacrimal drainage surgery. The specimens were cultured and results analyzed.Results:
Of 86 cases, 87.2% yielded a positive culture result. The majority of microorganisms were gram positive bacteria (73.3%) with Staphylococcus Aureus being the most frequently cultured species (36%) of the sample. Gram negative bacteria represented 26.7% of the isolates. The most common gram negative bacteria were Pseudomonas, Klebsiella, and E. coli which were isolated in 8% of the cases each. Staphylococcus aureus was isolated from 28.6% of cases having epiphora with no clinical signs of lacrimal drainage system infection. Ciprofloxacin (96%) and Gentamycin (94.7%) were found to be the most sensitive antibiotics against isolated organisms.Conclusions:
Adult patients with lacrimal drainage system obstruction harbor microorganisms in their lacrimal sacs indicating the importance of investigating patients before planning for intraocular surgeries and considering prophylactic use of antibiotics before lacrimal drainage procedures
