Fuchs Dystrophy

Overview

Fuchs endothelial corneal dystrophy is a progressive condition affecting the cells that pump fluid out of the cornea. As these cells decline, the cornea can swell and lose clarity.

Symptoms

Early symptoms may include hazy vision on waking that clears later, glare, halos, reduced contrast, and difficulty driving at night. Advanced swelling can cause persistent blur, discomfort, or painful surface blisters.

When to see a doctor

Schedule an examination for recurring morning haze, increasing glare, or gradual loss of clarity. Sudden painful blur, marked redness, or rapid visual change should be evaluated promptly.

Causes

Fuchs dystrophy usually reflects inherited and age-related loss of corneal endothelial cells. When too few healthy cells remain, fluid accumulates within the cornea.

Risk Factors

Risk increases with family history and age and is more common in women. Cataract surgery or other stress on the cornea may reveal or worsen swelling when endothelial reserve is limited.

Complications

Progressive edema can cause persistent cloudy vision, painful epithelial blisters, scarring, and reduced visual function. Corneal health can also influence planning for cataract surgery.

Diagnosis & Treatment

Evaluation may include slit-lamp examination, corneal thickness measurement, endothelial cell imaging, and assessment of cataracts or other causes of blur. Early care may include hypertonic drops or ointment and monitoring. Advanced disease may require referral for endothelial corneal transplantation.

Plan ahead for clearer vision

Careful monitoring helps guide treatment and cataract planning. Bespoke Eye Care provides corneal assessment and coordinated specialty referral in Chester Springs.
