Fuchs' Dystrophy is usually diagnosed at about 50 years of age, as this is when it starts causing vision problems. People in their 30's and 40's have few visual symptoms. Symptoms include hazy vision in the morning that gets better during the day. The reason is that fluid builds up in the cornea when you keep your eyes closed to sleep. During the day your corneas dries when your eyes are open. Later too much fluid builds up and cannot dry during the day and your vision stays blurry all day. Blisters form in the cornea that get bigger and eventually break. This can cause scarring of the cornea.
Other symptoms include:
An eye with a normal cornea. The clear window at the front of the eye.
Fuchs' dystrophy with blisters forming due to excessive fluid.
