Internal Limiting Membrane Peeling-reposition to Treat Idiopathic Macular Holes

Surgery Clinical Trial

Official title: Comparing the Surgical Outcomes of Internal Limiting Membrane Peeling-reposition Versus Peeling in Idiopathic Macular Holes: A Randomized Controlled Trial

Status Completed

Clinical Trial Summary

To compare the morphologic and functional outcomes of internal limiting membrane peeling-reposition versus peeling in idiopathic macular holes

Clinical Trial Description

This randomized clinical trial will be performed at a single center. Eligible patients with idiopathic macular holes will be equally randomized to internal limiting membrane (ILM) peeling-reposition group or ILM peeling group through computer-aided random allocation. A standard 3-port pars plana vitrectomy was performed by a single surgeon using the Constellation 23 gauge vitrectomy system (Alcon Laboratories Inc, Fort Worth, Texas, USA).After posterior vitreous detachment was achieved, peeling of the ILM was performed by an end gripping forceps with the assistance of Brilliant Blue G. In ILM peeling-reposition group, the peeled ILM flap is flatten back to peeled area with assistance of perfluoro-n-octane. In ILM peeling group, a round shape with 2.5 to 3.5 disc diameter of ILM is peeled. This is followed by a complete fluid-gas exchange. Patients are encouraged to maintain a face-down position for two weeks postoperatively in two groups. Postoperative measurements of BCVA and spectral domain optical coherence tomography(SD-OCT) are conducted at 1,3 and 6-month follow-up visits by independent masked observers. Macular light sensitivity and fixation stability are determined with microperimetry at 1,3, and 6 months of follow-up. Mf-ERG, M-score chart and VFQ-25 chart are performed 1,3, and 6 months of follow-up. Comparison of BCVA, anatomical closure were primarily performed between the two groups. Then, the morphologic changes of inner retina and the functional parameters measured from microperimetry, Mf-ERG, M-score chart, VFQ-25 chart were analyzed. ;
