Macular hole is an infrequent retinal pathology (2 to 4/1000) which most often affects people aged over 60, and twice common in women than men.
The vast majority of cases are idiopathic. Without treatment, the macular hole evolves through a series of stages until the extension of the diameter (up to 500 microns and higher values). With a fully developed macular hole, patients complain of metamorphopsia and decreased visual acuity.
This pathology has clearly benefited from advances in microsurgery and better understanding of its pathophysiology. Macular hole treatment has evolved to include small-gauge pars plana vitrectomy with or without internal limiting membrane (ILM) peeling and placement of intraocular gas tamponade.
The postoperative closure rate is close to 80%, but strongly depends on the initial characteristics of the hole, its diameter remaining the main prognostic factor. Thus for macular holes <400 microns, the closure rate is close to 92% dropping to 56% for macular holes above 400 microns. In case of surgical failure, one or more reoperations can be proposed, but with a lower closure rate.
The quest for a surgical technique presenting a greater success rate is a common goal to all retinologists.
Here the investigators propose a new surgical technique, derived from the FLAP method, and consisting of an inner limiting membrane transposition.
The objective of this study is to evaluate the feasibility of a new surgical technique for the treatment of macular holes already operated but without macular hole closure, allowing these patients a new therapeutic alternative. The success of this technique will be confirmed by detecting postoperatively the presence of the transposed internal limiting membrane into the foveal region.

ANATOMICAL AND VISUAL OUTCOMES OF INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE VERSUS INTERNAL LIMITING MEMBRANE PEELING IN MYOPIC MACULAR HOLE WITHOUT RETINAL DETACHMENT: A Preliminary Retrospective Study.
To compare the results of vitrectomy with internal limiting membrane (ILM) peeling and inverted ILM flap for treating myopic macular hole without retinal detachment.

Perforations through the whole thickness of the retina including the macula as the result of inflammation, trauma, degeneration, etc. The concept includes retinal breaks, tears, dialyses, and holes.
A membrane on the vitreal surface of the retina resulting from the proliferation of one or more of three retinal elements: (1) fibrous astrocytes; (2) fibrocytes; and (3) retinal pigment epithelial cells. Localized epiretinal membranes may occur at the posterior pole of the eye without clinical signs or may cause marked loss of vision as a result of covering, distorting, or detaching the fovea centralis. Epiretinal membranes may cause vascular leakage and secondary retinal edema. In younger individuals some membranes appear to be developmental in origin and occur in otherwise normal eyes. The majority occur in association with retinal holes, ocular concussions, retinal inflammation, or after ocular surgery. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p291)
Nerve cells of the RETINA in the pathway of transmitting light signals to the CENTRAL NERVOUS SYSTEM. They include the outer layer of PHOTORECEPTOR CELLS, the intermediate layer of RETINAL BIPOLAR CELLS and AMACRINE CELLS, and the internal layer of RETINAL GANGLION CELLS.
A group of disorders involving predominantly the posterior portion of the ocular fundus, due to degeneration in the sensory layer of the RETINA; RETINAL PIGMENT EPITHELIUM; BRUCH MEMBRANE; CHOROID; or a combination of these tissues.
The inner layer of CHOROID, also called the lamina basalis choroideae, located adjacent to the RETINAL PIGMENT EPITHELIUM; (RPE) of the EYE. It is a membrane composed of the basement membranes of the choriocapillaris ENDOTHELIUM and that of the RPE. The membrane stops at the OPTIC NERVE, as does the RPE.
