Fuchs' Endothelial Corneal Dystrophy (FECD)

Fuchs' Endothelial Corneal Dystrophy (FECD) is a progressive eye condition in which the innermost layer of the cornea, called the endothelium, gradually deteriorates. The endothelium helps keep the cornea clear by managing fluid balance. When it weakens, fluid leaks into the cornea, causing swelling, cloudiness, and visual disturbance. Symptoms often include blurry or foggy vision, especially in the morning. FECD mainly affects middle-aged and older adults and can worsen over time, sometimes requiring corneal transplant surgery to restore clarity and vision. The exact cause is unknown but involves genetic and environmental factors.
