Condition
Fuchs endothelial dystrophy
Clinically reviewed · Last reviewed 2026-06-13
What it is
The inner lining of the cornea normally pumps fluid out to keep the cornea clear. In Fuchs dystrophy these cells slowly die, fluid builds up overnight, and the cornea becomes cloudy.
Common symptoms
Symptoms build slowly over years.
- Blurry or hazy vision, often worse on waking
- Glare and halos around lights
- Gradual difficulty with contrast and reading
- Sometimes a rough or swollen corneal surface
Causes
It is usually inherited and more common in women. It is unrelated to Fuchs heterochromic uveitis. Cataract surgery can temporarily worsen swelling, so planning with a corneal specialist helps.
Treatment
Early cases may use salty drops or ointment to reduce swelling. Advanced disease is treated with partial-thickness corneal transplant techniques that replace only the inner layer, with good success rates.
Treatments & Surgery
Frequently asked questions
Why is vision worse in the morning with Fuchs dystrophy?
The cornea swells overnight when the inner pump cells are weak, then may clear somewhat during the day. Morning blur is a classic pattern.
Is Fuchs dystrophy the same as cataracts?
No. Fuchs dystrophy affects the cornea's inner lining, while cataracts cloud the lens inside the eye. Both can cause glare and blur.
Can Fuchs dystrophy be cured?
Drops can help early swelling, but advanced cases are often treated successfully with modern partial corneal transplants that replace the diseased inner layer.
