Klebsiella Endophthalmitis as Retinal Vasculitis with Prostatic Abscess.

Purpose To describe an unusual case of endogenous Klebsiella endophthalmitis associated with prostatic abscess in an immunocompetent patient. Case Report A 59-year-old previously healthy man presented with rapidly progressive retinal vasculitis in the left eye. He received an empirical antibiotic and antiviral agent intravenously followed by oral prednisolone until the etiology was identified; however, intraocular inflammation in the left eye continued to worsen, followed by the development of subretinal abscess in the contralateral eye. Finally, a diagnosis of endogenous Klebsiella endophthalmitis associated with prostatic abscess was made through a culture of the vitreous acquired by diagnostic vitrectomy. However, we could not save the vision of the left eye despite the intensive treatment with intravenous and intravitreal injections of antibiotics. Conclusions Rapidly progressive retinal vasculitis could be an initial sign of endogenous Klebsiella endophthalmitis even in an immunocompetent patient.
