Bacterial Endophthalmitis

ClinConnect Summary

Endophthalmitis is a serious ocular infection that can result in blindness. Approximately 70 percent of cases occur as a direct complication of intraocular surgery. Current management requires culture of intraocular contents and administration of an antibiotic. Vitrectomy surgery, which may help to manage endophthalmitis by removing infecting organisms and their toxins, has been shown to be of value in various animal models of endophthalmitis. However, human studies have not shown an advantage to vitrectomy with intraocular antibiotics compared with intraocular antibiotics alone.

Eligibility criteria

  • Men and women were eligible for entry into the EVS if they had clinical signs and symptoms of bacterial endophthalmitis in an eye that had cataract surgery or lens implantation within 6 weeks of onset of infection. The involved eye had to have either hypopyon or enough clouding of anterior chamber or vitreous media to obscure clear visualization of second-order arterioles, a cornea and anterior chamber in the involved eye clear enough to visualize some part of the iris, and a cornea clear enough to allow the possibility of pars plana vitrectomy. The eyes had to have a visual acuity of 20/50 or worse and light perception or better.
  • Patients were ineligible when the involved eye was known at the time of study entry to have had any pre-existing eye disease that limited best-corrected visual acuity to 20/100 or worse before development of cataract, any intraocular surgery before presentation (except for cataract extraction or lens implantation), any treatment for endophthalmitis before presenting at the study center, or any ocular or systemic condition that would prevent randomization to any of the study groups.
