Changes of macular structure and retinal thickness in macular area after vitrectomy for idiopathic macular hole

Abstract

AIM:The repair of macular structure after 23G vitrectomy was performed in patients with idiopathic macular hole, and the changes of retinal thickness in vision and macular area were analyzed.METHODS: A total of 85 patients(85 eyes)with monocular idiopathic macular hole who underwent elective surgery in our hospital from June 2016 to December 2017 were included in the study, of which 37 were male and 48 were female, with an average age of(64.7±10.1)years. All subjects underwent 23G vitrectomy were observed the closure of macular hole after operation, and the changes of retinal thickness in macular forea were observed preoperatively and postoperatively by optical coherence tomography(OCT). To observe the changes of the best corrected visual acuity(BCVA)in preoperative, 1mo, 3mo and 6mo after operation.RESULTS: All subjects underwent postoperative examinations had good macular hole closure. The average BCVA of 3mo and 6mo after operation were significantly higher than that of preoperative and 1mo after operation(Pt=7.983, P=0.037). The macular central fovea thickness in 1mo after operation was significantly higher than preoperative and 3mo, 6mo after operation(PCONCLUSION:The treatment of idiopathic macular hole with 23G vitrectomy had a high degree of successful closure rate of fracture hole and the visual acuity of patients was obviously improved.
