Presumed intraocular nocardiosis in a cardiac-transplant patient.

A 44-year-old cardiac-transplant patient receiving immunosuppressive therapy developed a chorioretinal mass OS. The lesion was consistent with an ocular nocardial infection. The patient also developed a testicular abscess that was shown to contain N. asteroides after orchiectomy. Despite appropriate systemic treatment, the patient developed extensive subretinal scarring OS. This case report is the first to describe an opportunistic ocular infection with N. asteroides after cardiac transplantation.
