CME Credits: 1.00

A 74-year-old woman was referred for evaluation of retinal lesions in her left eye. Her ocular history was notable for recent cataract surgery 5 weeks prior to presentation that was complicated by endophthalmitis. A normal funduscopic examination was documented prior to cataract surgery. At the time of initial presentation to her local retina specialist 1 week following her cataract surgery, the patient had severe pain and redness. Her visual acuity was light perception. An examination revealed a 2-mm hypopyon and dense vitreous haze with no view of the retina. She was treated for presumed endophthalmitis with a vitreous tap and intravitreal injections of vancomycin (1 mg/0.1 mL), ceftazidime (2.2 mg/0.1 mL), and dexamethasone (0.4 mg/0.1 mL). The vitreous sample obtained at the time of treatment grew Staphylococcus caprae susceptible to vancomycin.
