About

The main objective of this study is to evaluate the therapeutic effectiveness of the internal limiting membrane (ILM) peeling and translocation surgery compared to the conventional surgical approach for treating large idiopathic macular hole (IMH) through a well-designed prospective randomized controlled clinical trial. This study aims to compare the new surgical approach to the conventional approach in terms of improving visual function, promoting macular retinal anatomical healing, and enhancing patients' quality of life. By conducting this prospective clinical trial, establishing a database, and generating clinical reports and evidence-based medicine on the therapeutic efficacy of the ILM peeling and translocation surgery for large IMH.

Inclusion criteria

Participants who can understand the purpose of this clinical trial, volunteer to participate, sign an informed consent form, and can complete the postoperative follow-up on time.
Participants diagnosed with idiopathic macular hole (IMH).
Based on OCT scans, the minimum horizontal diameter of the macular hole is >500 and <900 µm.
Participants with an axial length <26.0mm and a myopic degree lower than 6D.
For participants with bilateral macular holes, the eye with a larger hole diameter will be included.
