Symptoms of Fuchs Dystrophy

Signs and Symptoms

Blurred vision may be first sign of Fuchs Dystrophy.  The blurred vision results from fluid collecting in the cornea while during sleep.  This excess fluid evaporates over the course of the day, which leads to reduced swelling and better vision.  As the disease advances, these periods of periods of swelling, impaired vision, and pain last longer.

Other symptoms include:

  • Coarse, rough feelings in the eye, occasionally accompanied by sharp pains.  This is due to fluid collecting underneath the front layer of corneal cells called the epithelium.
  • Discomfort in bright light.  Patients often find that they need to wear sunglasses or even wraparound sunglasses and sun visors together.
  • Fluctuating eyesight.  Eyesight gets better and worse throughout the day or from day to day.
  • Halos around lights.

  • Poor night vision (due to halos around lights, poor contrast between colors, and glare from bright lights).
  • Blurry vision with poor contrast.  Many Fuchs patients describe their vision as similar to having grease smeared on their eyeglasses.
