This pulls on the retina and causes distorted vision.Ībout 20 percent of people in the United States over the age of 75 have ERMs, although not all cases are severe enough to require treatment. This defect can be caused by age, retinal tears, and diseases like diabetes, which affect vascular regions in the eye.ĮRMs begin with cells growing on the smooth retinal membrane. They’re caused by a defect in the surface lining of the retina. Epiretinal membranes (ERMs)ĮRMs are also called macular puckers. Wet AMD is more likely to produce metamorphopsia than dry AMD. The macula gets thinner due to aging, where yellow-colored lipid fatty proteins (called drusen) clump under the surface, causing vision loss. There’s no leakage of fluid or blood into the macula. Blood vessels leak fluid or blood into the macula (less common than dry AMD). 18.6 percent experienced distortions of faces.21.6 percent had distortions of lines of bathroom tile.22.6 percent noticed distortions of window frames and bookshelves.45 percent of study subjects had visual distortions of lines (for example, newsprint or computer displays).In one 2018 study looking at AMD and metamorphopsia: possibly related to environmental factors like diet and smoking.the leading cause of vision loss among those 50 years and older.
The National Eye Institute reports that AMD is: These include: Age-related macular degeneration (AMD)ĪMD is a common degenerative disorder affecting the macula, the part of your eye that lets you see in sharp focus and fine detail. Metamorphopsia can be a symptom of a variety of eye disorders that affect the retina and macula.
