Abstract:
AIM:To compare the clinical effects of 25G+ and 27G+ transconjunctival sutureless vitrectomy in treating idiopathic macular hole.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 time and intraoperative complications were recorded and patients were followed up for 3-6mo.During the follow up period, best correct vision acuity (BCVA), intraocular pressure, macular hole healing and postoperative complications were documented and statistically analyzed.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=0.57, 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=0.31).There was no significant difference between preoperative and postoperative intraocular pressure at 1wk after operation in both groups (P=0.72, 0.92).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.
