誗AIM:To compare the clinical effects of 25G + and 27G+ transconjunctival sutureless vitrectomy in treating idiopathic macular hole. 誗 METHODS: We retrospectively reviewed the clinical outcomes of 56 eyes (56 patients) with idiopathic macular hole which were treated with micro-incision vitrectomy from June 2015 to September 2016. Patients were divided into two groups, 28 patients (28 eyes) were treated with 25G+ vitrectomy and the rest (28 eyes) were treated with 27G + vitrectomy. The operative

During the follow up period, best correct vision acuity (BCVA) , intraocular pressure, macular hole healing and postoperative complications were documented and statistically analyzed. 誗 RESULTS: BCVA in two groups were significantly improved after surgery (P < 0. 001) and there was no significant difference between the two groups (P = 0. 84). No serious complications occurred. No statistically significant difference was found between the two groups in surgical time and healing rate of macular hole (P = 0郾 57, 0. 64). The incidence of low intraocular pressure (IOP < 10mmHg) in 27G + group was lower than that in 25G+ group on the first day after surgery(P = 0郾 31). There was no significant difference between preoperative and postoperative intraocular pressure at 1wk after operation in both groups (P = 0. 72, 0. 92). 誗CONCLUSION: Both 25G+ and 27G+ vitrectomy are safe and effective technique in treating idiopathic macular hole. Besides, 27G + showed better superiority on the maintenance of intraocular pressure and reduce the trauma. 誗 KEYWORDS: idiopathic macular hole; 27G + transconjunctival sutureless vitrectomy; vitreoretinal disease Citation:Liu SM, Li DF, Li J, et al.
