To describe the risk factors, clinical course, ancillary test findings, treatment strategies, and visual outcomes of a series of patients with choroidal abscesses caused by endogenous Nocardia.This retrospective, consecutive noncomparative case series included all patients with Nocardia ocular infections at 3 tertiary medical centers over the past 20 years.Five eyes in 5 patients were identified with choroidal abscesses because of Nocardia. All patients were immunocompromised: one suffered from AIDS and four had autoimmune disorders. Three of the 5 patients (60%) underwent systemic evaluation, and in all 3, nonocular nocardiosis was identified. Four patients (80%) underwent diagnostic ophthalmic surgery and received systemic and intravitreal antibiotics. The final patient deferred these interventions. Outcomes at the last follow-up examination were 20/25, 1/200, hand motion at 1 foot, and 2 patients underwent enucleation. Mean follow-up (± standard deviation) was 159 (± 103) days.Immunosuppression is the most significant risk factor for developing Nocardia choroidal abscesses. Definitive diagnosis generally requires subretinal biopsy, which is also critical to implementing appropriate antibiotic therapy.
