Vitreous culture revealed Staphylococcus coagulase-negative bacteria. He was subsequently treated with intravitreal antibiotics and oral prednisone.Results: The endophthalmitis resolved with a best corrected visual acuity of 6/200 with the presence of an epiretinal membrane.Conclusions: Possible contributing factors to endophthalmitis following sutureless vitrectomy include decreased vitreous irrigation/lavage, lack of a watertight wound, and/or vitreous wicking, all of which may promote intraocular bacterial entrance. A sutureless vitrectomy system may increase the risk of vitrectomy-associated endophthalmitis.Keywords: endophthalmitis, 25-gauge vitrectomy, vitreous wick, sutureless, high flow lavag
