Abstract Details

Purpose:

To determine the percentage distribution of different organisms grown on culture by doing Conjunctival swab culture prior to surgery and the incidence of Endophthalmitis post surgery.

Setting:

Retrospective single center study at Indira Gandhi Eye Hospital,Lucknow,Uttar Pradesh,INDIA.

Methods:

Retrospective study. Period of Study: August 2014 to October 2014. Standard procedure for Conjunctival Swab (CS) was carried out after Informed consent by the same technician and laboratory.Patients with positive culture were started on topical antibiotic drops as per sensitivity report.CS was repeated until "No growth" and then patient was operated upon.

Results:

56/108 patient samples showed growth.Out of 56 patients 38 were positive once and 18 were positive twice(74 positive samples in total).Out of 74 samples, 62 were coagulase negative ,1 each were Diphtheroids and Streptococcus viridans which are considered non virulent.The significant virulent organisms were 7 samples of Staphylococcus aureus,2 of Pseudomonas aeruginosa and 1 of Enterococcus. 80 out of 108 patients were operated and 28 did not get operated at our Hospital.None of the operated patients developed endophthalmitis.

Conclusions:

CS is useful prior to surgery to detect virulent organisms. None of the operated patients developed endophthalmitis. 20 out of 28 patients(71.43%) not operated upon had positive samples as compared to 36 out of 80 operated patients(45%) preoperatively.This may be a disadvantage of repeated CS,since a larger percentage of patients not operated were positive. This shows that some patients may be lost due to repeated CS.Patients need to be counselled about the importance of CS thus preventing loss of One eyed patients and minimizing the risk of Endophthalmitis by operating only after "No growth" of virulent organisms.
