Bilateral endogenous Escherichia coli endophthalmitis: a devastating complication in an insulin-dependent diabetic.

This condition appears to occur almost exclusively in diabetics, and is invariably related to a urinary tract infection. Treatment of any infection in diabetics should be aggressive, and any deterioration in vision should be addressed promptly.
