PURPOSE: To report a case of an iris abscess and necrotizing sclerokeratitis caused by Mycobacterium abscessus and presenting as hemorrhagic uveitis.
METHODS: An 86-year-old white woman was diagnosed with hemorrhagic anterior uveitis and treated with high-frequency topical steroids. The inflammation progressed to involve the cornea and the sclera, and the treatment was changed to intensive antibiotics. There was no improvement. Direct microscopy of a biopsy specimen of the lesion wrongly identified Nocardia as the cause, but antibiotic sensitivity suggested clarithromycin as a suitable therapeutic agent. Therapy was changed but there was continued deterioration. The eye could not be saved and the causative organism was subsequently discovered to be M. abscessus.
RESULTS: The eye was enucleated 6 months after initial presentation.
CONCLUSIONS: Ocular infection with M. abscessus is an extremely rare cause of necrotizing sclerokeratitis and may present as a hemorrhagic uveitis. There is a high risk of misdiagnosis and late detection, which may have severe consequences.
