BACKGROUND AND OBJECTIVE: To report the rates of hypotony after 25-gauge vitrectomy.
PATIENTS AND METHODS: A retrospective review of 111 consecutive cases was performed in patients undergoing transconjunctival 25-gauge pars plans vitrectomy with either air or gas as a tamponade agent. The primary outcome measure was postoperative intraocular pressure less than 5 mm Hg. A Wilcoxon rank-sum test was conducted to determine the statistical significance of continuous variables in association with rates of hypotony.
RESULTS: The overall incidence of hypotony on postoperative day 1 was found to be 8.1%. The rate of hypotony was 16.7% in uveitis cases and 0% in routine macular surgery. The rate of hypotony in cases in which sutures were used was 41.7%, compared to 4% in cases in which sutures were not used (P = .001).
CONCLUSION: Hypotony rates were significantly higher after 25-gauge transconjunctival pars plana vitrectomy in uveitis and some other conditions.
