Cataract extraction is a commonly performed operation in the United
States, with 1.3 million procedures performed annually. Postoperative endophthalmitis
is a potentially devastating complication, with an incidence of approximately
0.1% to 0.3%.1-2 We report
herein an evaluation of an outbreak of postoperative endophthalmitis.
This outbreak was investigated by the North Carolina Statewide Program
for Infection Control and Epidemiology. Patient cultures were performed in
a hospital microbiology laboratory. Environmental cultures were processed
as follows. Medication vials and water samples were processed by filtration
using a disposable filter (MSI Savur Analytical filter; Osmonics, Minnetonka,
Minn) placed on either sheep blood or D/E-neutralizing agar. Fluids too viscous
for filtration (eg, Keri Lotion) were plated directly onto suitable media.
Environmental surfaces (eg, sink drains) were cultured using a sterile swab
premoistened with trypticase soy broth and then plated directly onto appropriate
agar.
To determine the relatedness of Pseudomonas aeruginosa isolates, we performed pulsed-field gel . . . [Full Text of this Article] Report of Cases
