Electrolysis-needle cauterization of corneal vessels in patients with lipid keratopathy.

PURPOSE: To describe a case of infectious scleritis caused by methicillin-resistant Staphylococcus aureus (MRSA) after pars plana vitrectomy despite treatment with topical fourth-generation fluoroquinolones.

METHODS

Single interventional case report.

RESULTS

A 72-year-old man presented with scleral thinning and subconjunctival abscess 1 month after pars plana vitrectomy. Microbiological studies including cultures and antibiotic sensitivity were performed. Culture of the scleral abscess showed growth of MRSA resistant to fourth-generation fluoroquinolones and sensitive to vancomycin and erythromycin. Treatment with a combination of topical vancomycin and systemic erythromycin for 6 weeks resolved the infectious scleritis.

CONCLUSIONS

MRSA can be a cause of infectious scleritis after ocular surgery without a clear source despite surgical prophylaxis with topical fourth-generation fluoroquinolones.
