Macular Resurfacing Using Autologous ILM Patch Transposition for Idiopathic Epiretinal Membrane
Sponsor: Peiquan Zhao
Summary
Idiopathic epiretinal membrane is a condition in which abnormal tissue grows on the surface of the retina and can cause blurred vision and distortion. The standard surgical treatment is removal of this membrane, but some patients may not achieve complete visual recovery because the normal structure of the central retina may not fully restore after surgery. This study is a prospective randomized controlled trial designed to evaluate a new surgical technique called macular resurfacing using an autologous internal limiting membrane patch transposition. The technique uses a patient's own retinal tissue to cover the macular area after epiretinal membrane removal, with the aim of promoting more natural healing of the retinal surface. Patients with idiopathic epiretinal membrane will be randomly assigned to receive either the new surgical technique or conventional epiretinal membrane peeling. Visual function and retinal structural changes will be evaluated using visual examinations and multimodal retinal imaging during follow-up. The study aims to determine whether this new technique can improve visual outcomes and promote better restoration of macular microstructure.

Non-Inverted Autologous Internal Limiting Membrane (ILM) Patch Transposition
After standard pars plana vitrectomy and epiretinal membrane removal, the internal limiting membrane (ILM) was peeled from the central fovea to the vascular arcades. A piece of healthy ILM free of ERM from the paramacular region was prepared as a patch for subsequent coverage, while its pedicle remained anchored to the paramacular site. A perfluorocarbon liquid bubble was injected into the vitreous cavity to flatten the ILM patch and facilitate manipulation. The patch was then detached and carefully transposed to resurface the macular area.
Conventional Epiretinal Membrane and Internal Limiting Membrane Peeling
After standard pars plana vitrectomy and epiretinal membrane removal, the ILM was peeled from the central fovea to the vascular arcades, without additional ILM patch transplantation.
