Retinal Diseases
Also called:
Cellophane Maculopathy; Macular Pucker; Premacular Fibrosis
Definitions related to epiretinal membrane:
-
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 EPITHELIUM. 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.

-
An epiretinal membrane is a thin sheet of fibrous tissue that can develop on the surface of the macular area of the retina and cause a disturbance in vision. An epiretinal membrane area can develop on the thin macular area of the retin. An epiretinal membrane is also sometimes called a macular pucker, premacular fibrosis, surface wrinkling retinopathy or cellophane maculopathy.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Wrinkling or bulging of contracted scar tissue that has formed on retinal surface secondary to retinal injury, inflammation, blood vessel occlusion, or vitreous detachment.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Epiretinal membrane is formation of a thin, fibrotic membrane over the retina that contracts, wrinkling the underlying retina and interfering with vision. Epiretinal membrane typically occurs after age 50 and is most common among people > 75.Merck & Co., Inc., 2020
