Infectious Scleritis: What the ID Clinician Should Know.

Scleritis is an inflammatory process involving the outer coating of the globe which is characterized by focal or diffuse hyperemia, moderate to severe pain, and frequent impairment of vision. Most cases of scleritis are autoimmune in nature and are managed with topical and/or systemic corticosteroids. Infectious scleritis is a less common entity, occurring in 5%-10% of cases, and requiring directed antimicrobial therapy. We present a case of anterior nodular scleritis diagnosed via positive culture of an excisional biopsy of a scleral nodule. The patient improved after combined surgical and medical therapy with amoxicillin-clavulanate and moxifloxacin for 12 months. Based on a literature review, a summary of reported cases of infectious scleritis is provided, and guidelines pertaining to diagnosis and management are offered.
