Management and outcome of microbial anterior scleritis.

PURPOSE: To evaluate the prevalence, predisposing factors, and outcomes of bacterial and fungal scleritis.

METHODS

We reviewed the clinical findings, therapeutic interventions, and visual outcomes of patients with suppurative scleral inflammation without preceding microbial keratitis who had microorganisms isolated from scleral scrapings.

DESIGN

Retrospective interventional case series.

RESULTS

Of 349 patients with scleritis diagnosed from 1999 to 2009, 6 adults (1.7%) presented with suppurative inflammation of the anterior sclera due to Pseudomonas aeruginosa (2), Streptococcus pneumoniae (2), Staphylococcus aureus (1), and Scedosporium apiospermum/Pseudallescheria boydii (1). Each had ocular surgery of the affected eye before presentation. Intraocular extension occurred in 2 eyes. After local and systemic antimicrobial therapy, all improved without evisceration or enucleation, and 4 attained vision of 20/60 or better.

CONCLUSIONS

Bacterial or fungal scleritis is an uncommon ocular infection that can belatedly follow anterior segment procedures. Antimicrobial therapy and surgical intervention can successfully control progressive suppuration and reduce vision-limiting complications.
