Endophthalmitis After Vitreoretinal Surgery

Endophthalmitis after vitreoretinal surgery is uncommon but one of the most serious complications associated with severe visual loss despite appropriate treatment. It can be diagnosed based on symptoms such as ocular pain, conjunctival hyperemia, corneal congestion, corneal edema, anterior chamber inflammation, hypopyon, and vitreous haziness. The most common agents responsible for postoperative endophthalmitis are bacteria from patients' own ocular surface flora. Several factors such as preoperative sterilization, surgical nature of the procedure, intraocular tamponade, and postoperative treatment methods are responsible for the development of endophthalmitis after pars plana vitrectomy. The prognosis of endophthalmitis depends on the virulence of the microorganism, the patients’ immune nature, the time of diagnosis, and the initiation of treatment.
