Study of Surgery in Patients With Idiopathic Macular Hole

A Randomized, Double-masked, Multicenter, Controlled Study of Effects of Internal Membrane Peeling Surgery in Patients With Idiopathic Macular Hole Measured by Optical Coherence Tomography.

The purpose of this study is to determine the effects of two different internal limiting membrane peeling with distinct diameters after macular hole surgery on anatomical closure grades.

The purpose of this study is to investigate two distinct diameter of internal limiting membrane peeling on anatomical outcomes of macular hole surgery with different preoperative idiopathic macular hole.
