Fuch's (fyooks) Dystrophy is a disorder of the cornea (the clear front "window" of the eye) where the cornea becomes cloudy and waterlogged, sometimes causing painful blisters to form and blur vision.

This disorder occurs more often in women and is usually inherited. Although it generally begins between the ages of 30 and 40, it is more common between 50 and 60.

With Fuch's Dystrophy, the bottom-most layer of the cornea, the endothelium, breaks down and causes the cornea to swell. As you sleep, the cornea will swell with water, which will evaporate while you are awake. But as the disorder worsens, the swelling will remain during the day and your vision will blur.

Common symptoms of Fuch's Dystrophy include glare and light sensitivity, a sandy sensation, fluctuating vision, or hazy vision that's usually worse in the morning.

Although the disease cannot be cured, it can be controlled with eye drops, ointments, or contact lenses. Your doctor may recommend using a hair dryer to blow air across the eyes and help relieve symptoms. In rare instances, a corneal transplant may be necessary if medicines are no longer effective in treating the disease.
