Abstract Bacterial endophthalmitis was diagnosed clinically in a patient who developed ocular inflammation three days after uneventful intracapsular cataract extraction. Aqueous humor aspirations revealed Gram-negative rods. Culture of the aqueous humor showed the organism to be Proteus morgagnii. Because of rapid progression of endophthalmitis, a solution containing 0.4 mg of gentamicin sulfate and 0.4 mg of dexamethasone was injected into the vitreous and anterior chamber. Subsequently, there was a substantial improvement in the clinical course. The vision improved from light perception to 5/200 with corrective lenses. The electroretinogram was normal. References 1.
