PURPOSE
To investigate the incidence and risk factors of major complications including postoperative hypotony after 23-gauge transconjunctival sutureless vitrectomy in previously vitrectomized eyes. METHODS: The authors retrospectively reviewed medical records of 52 eyes, which underwent 23-gauge transconjunctival sutureless vitrectomy of previously vitrectomized eyes by a single surgeon. Major outcomes were postoperative hypotomy (<6 mmHg), intraoperative sclera shrinkage during sclerotomy,and other postoperative complications. Multiple logistic regression analysis was performed that included 212 eyes with primary vitreoretinal surgery in order to validate secondary vitreoretinal surgery as a significant risk factor of postoperative hypotony. RESULTS: Postoperative hypotony occurred in 4 eyes (7.7%) out of 52 eyes that underwent a second vitrectomy. The odds ratio of the second vitreoretinal surgery (OR=1.15, p=0.283) was not significant by multiple logistic regression analysis that included age, sex, axial length of globe, and the number of surgeries as the independent variables. Choroidal detachment occurred in one eye but disappeared three days later. The intraocular pressure was normalized within one week in all cases. Scleral shrinkage during sclerotomy occurred in five eyes (9.6%), and there were no other major complications, such as endophthalmitis. CONCLUSIONS: A 23-gauge transconjunctival sutureless vitrecomy of previously vitrectomized eyesshowed a 7.7% incidence of postoperative hypotony and favorable prognosis. |
