What is Fuchs Endothelial Dystrophy?
Fuchs Endothelial dystrophy is a genetic eye condition that results when the back surface of the cornea (known as the endothelium) breaks down, allowing more fluid than normal into the cornea and causing it to swell. As the swelling progresses, the cornea becomes hazy and thus vision becomes blurred/cloudy. This may be worse in the morning upon waking. In more severe cases the swelling can cause blister-like lesions on the front surface of the cornea, causing pain when they rupture (usually in the morning), and possible infection.
