Abstract
In the present study, 37 eyes of 30 congenital dacryocystitis patients (7 bilateral) were studied, out of which 60% of patients were male and 40% female. Gram positive cocci constituted the major bacterial isolate (56.7%) with Streptococcus pneumoniae (27.9%) predominating. Most effective antibiotics against the commonest organism Streptococcus pneumoniae were Tobramycin and Gentamycin showing 100% effectivity. Staphylococcus albus 17.4% was the most common normal conjunctival commensal isolated.

Introduction
Congenital dacryocystitis is caused secondary to congenital abnormalities of the lacrimal drainage system. Impatency of naso-lacrimal duct at its lower end is the commonest cause of congenital dacryocystitis (1). It is due to an imperforate membrane at the lower end of naso-lacrimal duct and usually affects the babies with permanent closure of the Hasner membrane (2,3). In more than 90% of the new-borns, this membrane perforates spontaneously during first 4-6 weeks. Sometimes the perforation occurs after 6-12 months (4,5). After the age of 12 months a high pressure syringing to open the Hasner membrane is indicated (6). The two most important clinical features are persistent epiphora and regurgitation of mucoid or muco-purulent material on pressure over the sac. The present study was undertaken to know the common type of bacteria associated with congenital dacryocystitis and their antibiotic sensitivities & to guide the clinician better in his choice of medication.
Material and Methods
This prospective study was conducted on the patients attending the Out Patient Department of Upgraded Department of Ophthalmology for one year, in collaboration with the Department of Microbiology, Government Medical College, Jammu.
A total of 30 patients of either sex, involving both unilateral and bilateral cases were included in the study. The fellow unaffected eye in unilateral cases was taken as controls. Those cases previously surgically interfered with in the past were excluded.
The material for bacteriological analysis was taken from the affected eye in the form of regurgitant material or the conjunctival discharge itself, if there was no regurgitation. The material taken on sterile cotton-tipped swabs was streaked immediately on blood-agar and macConkey's agar plates and incubated at 37oC for 48 hours...
