Fuchs Dystrophy: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 23, 2026.
What kind of doctor treats Fuchs Dystrophy?
An ophthalmologist (a medical doctor who treats eye disease) usually treats Fuchs dystrophy, and a cornea specialist may do surgery. It most often affects both eyes. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Fuchs dystrophy?
Fuchs dystrophy is an eye disease. Cells lining the inner surface of the cornea slowly start to die off. The cornea is the clear front window of the eye.
These cells line the back of the cornea. They are called corneal endothelial cells, and they control how much fluid is inside the cornea. As more cells are lost, fluid builds up in the cornea. The cornea then swells and looks cloudy.
Fuchs dystrophy gets worse over time.
Symptoms
The first symptom is typically blurred vision in the morning that usually clears during the day. In the early stage, you may have few symptoms, if any.
In the later stage, blurry or hazy vision does not get better as the day goes on. Symptoms may include:
- Eye pain.
- Sensitivity to light and glare.
- Seeing colored halos around lights.
- A sandy or gritty feeling in the eyes.
Tiny blisters may form in the cornea. The blisters get bigger and eventually break open, causing eye pain.
Causes and who gets it
The genetics of Fuchs dystrophy are unclear. In some families, it is passed down from parents to children. It can also occur in people with no known family history.
The late-onset form is common. It affects about 4 percent of people over age 40 in the United States. Signs and symptoms usually begin in a person's forties or fifties. A very rare early-onset form starts to affect vision in a person's twenties.
Women are affected two to four times more often than men, for reasons that are unclear.
Small deposits called guttae can be seen during an eye exam. They form in the middle of the cornea and slowly spread.
How doctors diagnose it
An eye doctor can diagnose Fuchs dystrophy during a slit-lamp exam. A slit lamp is a microscope with a bright light.
Other tests may be done.
- Pachymetry measures the thickness of the cornea.
- A specular microscope exam lets the eye doctor look at the thin layer of cells that line the back of the cornea.
- A visual acuity test is also done. It checks how sharp your vision is.
The ophthalmologist also checks for tiny blisters on the front of the cornea and for the guttae.
Treatment
Treatment depends on how Fuchs dystrophy affects the cells of your eye. Your ophthalmologist will discuss which treatments are best for you.
Eye drops or ointments that draw fluid out of the cornea are used to relieve symptoms. For early Fuchs dystrophy, holding a hair dryer at arm's length to blow warm air on your face can help dry the surface of the cornea.
If painful sores develop on the cornea, soft contact lenses or surgery to create flaps over the sores may help reduce pain.
For very poor vision or scarred corneas, you may need a corneal transplant. In this surgery, healthy tissue from a donor is used. One type moves healthy endothelial cells into the cornea. The other replaces the center of the cornea with a healthy donor cornea.
A newer technique called endothelial keratoplasty (DSEK, DSAEK, or DMEK) has become the preferred option for people with Fuchs dystrophy. Only the inner layers of the cornea are replaced, instead of all the layers. This leads to a faster recovery and fewer complications, and stitches are most often not needed.
Without a corneal transplant, a person with severe Fuchs dystrophy may become blind or have severe pain and very reduced vision.
Mild cases often get worse after cataract surgery. A cataract surgeon will check this risk and may change the technique or the timing of the surgery.
When to see a doctor
Contact your provider if you have eye pain, sensitivity to light, or the feeling that something is in your eye when nothing is there. Also contact your provider for vision problems such as halos or cloudy vision, or for worsening vision.
Call 911 or go to the emergency room for a sudden change in vision.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can check for vision changes, refer you to an ophthalmologist, and help you keep up with eye visits along with your other health care.
Common questions
Can Fuchs dystrophy cause blindness?
It can, in severe cases. Without a corneal transplant, a person with severe Fuchs dystrophy may become blind or have severe pain and very reduced vision.
Is Fuchs dystrophy inherited?
Sometimes. In some families, it is passed down from parents to children. It can also occur in people with no known family history.
Why is my vision blurry in the morning with Fuchs dystrophy?
Morning blur happens because fluid can build up in the cornea during sleep, when the eye is closed. When you are awake, the fluid dries normally. In the early stage, vision may improve through the day.
Can cataract surgery make Fuchs dystrophy worse?
It can. Mild cases of Fuchs dystrophy often worsen after cataract surgery. A cataract surgeon will check this risk and may change the technique or the timing.
