Intravitreal antibiotic injection and vitrectomy in acute bacterial endophthalmitis.

Two days after an unplanned extra-capsular cataract extraction with sector iridectomy, a patient showed typical signs of bacterial endophthalmitis. Vitreous and aqueous were aspirated for culture, and gentamicin and dexamethasone were injected. Twenty-four hours later, after isolation of Staphylococcus epidermidis, a vitrectomy to remove the central vitreous was done. Postoperatively, vision progressively improved; at the last review nine months after vitrectomy, visual acuity was 20/50.
