Fuchs' endothelial dystrophy is a type of eye disease where the innermost layer of cells in the cornea begins to break down, leading to loss of vision. There are several synonyms that refer to the same condition, including Fuchs' corneal dystrophy, Fuchs' endothelial corneal dystrophy, Fuchs' dystrophy, and Fuchs' epithelial dystrophy. These terms are often used interchangeably to describe the same eye disorder. The disease is named after a German ophthalmologist, Ernst Fuchs, who first described the condition in 1910. Although the exact cause of Fuchs' endothelial dystrophy is unknown, it is more commonly diagnosed in women and in individuals over the age of 50.
