Microbiological spectrum of organisms isolated from explanted scleral buckles

Scleral buckle removal is an uncommon procedure performed for various reasons. Microbiological information on explanted scleral buckles remains limited. The authors identified 37 cases of scleral buckle removal during an 18-year period. Bacterial cultures isolated an organism in 4 of 9 patients (44%) with clinical infection. Organisms identified included methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, Mycobacterium abscessus, and coagulase-negative Staphylococcus species. Bacterial cultures isolated an organism in 3 of 11 patients (27%) without clinical infection. Organisms identified included Nocardia species, Alcaligenes xylosoxidans, and Mycobacterium chelonae. Scleral buckles appearing clinically infected may be associated with more virulent organisms and a greater chance of identifying an organism. Bacterial cultures may be of value for scleral buckles upon removal.
