Abstract:
A 54-year-old male presented to our ophthalmology clinic with a diagnosis of the right central retinal vein occlusion with macular edema. The patient was treated with dexamethasone intravitreal implant. Three days after the implant insertion, the patient experienced pain, redness and blurred vision in the same eye. With a provisional diagnosis of acute endophthalmitis, a combination of ceftazidime 2.25 mg/0.1 ml and vancomycin 1 mg/0.1 ml was injected intravitreally. One week after the treatment, endophthalmitis signs and symptoms subsided. This report presents a case of endophthalmitis following dexamethasone intravitreal implant, with a favorable outcome after treatment with intravitreal antibiotic injection without removal of the implant.
