Endogenous Escherichia coli endophthalmitis in a patient with autosomal-dominant polycystic kidney disease.

We examined a 67-year-old man with autosomal-dominant polycystic kidney disease who had right ocular pain and visual loss. Escherichia coli was grown from the vitreous aspirate. Despite treatment, no visual improvement was obtained, and the right globe was enucleated. We believe that the patient had a rare case of endogenous E. coli endophthalmitis.
