Demographic data of all patients like Age, Sex, Occupation and Socio economic status of patient, nature, duration of symptoms and other aspects mentioned in the proforma was included. Patients who had received either topical or systemic antibiotics for the past one week from their visit to the hospital were excluded. In the present study a total of 100 samples of patients were included in the study based up on inclusion criteria. Out of 100 cases under the study it is observed that the females affected were 51.43% in comparison with males 48.57%. Out of 100 cases which were obtained over a period of one year, 70 samples were culture positive and 30 samples were culture negative. Right eye involvement was noticed among 22 males (64.70%), and left eye 12 (35.30%), in females right eye involvement 12 (33.34%) and left eye involvement 24 (66.66%) was noticed.

The commonest organism in acquired dacryocystitis was Staphylococcus aureus (42.8%) followed by Staphylococcus epidermidis (37.4%) and enterococci (8.57%). Escherichia coli was the common organism (8.57%) followed by pseudomonas aeruginosa (2.85%). Dacryocystitis was most common in females than men. Females of middle age and above had higher incidence of dacryocystitis. Left eye was involved more than right eye.
