Endophthalmitis due to Listeria monocytogenes developed suddenly in a 52-year-old man receiving immunosuppressive therapy for a renal transplantation carried out 2 months previously. The treatment combined low doses of ciclosporin and prednisone. The initial clinical picture was of acute hypertensive uveitis with hypopyon. Despite prompt paracentesis and appropriate antibiotic therapy, the long-term course was unfavorable, and enucleation became necessary. The occurrence of listeriosis is classic in renal-transplant recipients, but no ocular form has been reported hitherto.
