As the disease progresses, Fuchs' dystrophy symptoms usually affect both eyes and may include:
- Glare, which is an early symptom and reduces contrast perception or affects vision in low light.
- Blurred vision, which occurs in the morning after awakening and gradually improves during the day. As the disease progresses, vision can take longer to improve or may not improve.
- Distorted vision, sensitivity to light, difficulty seeing at night and seeing halos around light
- Painful, tiny blisters on the surface of your cornea
- A cornea that looks cloudy or hazy
When your ophthalmologist examines your cornea, he or she looks for:
- Irregular bumps on the back surface of the cornea (guttae)
- Corneal swelling
- Corneal haze
- Thickening of the cornea, measured by a special instrument (typically an ultrasound)
When to see a doctor
If you experience some of these signs and symptoms, and especially if they get worse over time, see an eye specialist (ophthalmologist). If symptoms develop suddenly, call an ophthalmologist for an urgent appointment. Other eye conditions that cause the same symptoms as Fuchs' dystrophy also require prompt treatment.
