Understanding Fuchs Dystrophy
Fuchs Dystrophy, also known as Fuchs Corneal Dystrophy, is a genetic eye disorder that affects the cornea, the clear front surface of the eye. It is characterized by the gradual deterioration of the corneal endothelial cells, which are responsible for maintaining the cornea’s clarity and preventing it from becoming swollen or cloudy.
Individuals with Fuchs Dystrophy may experience symptoms such as blurred or cloudy vision, glare sensitivity, and eye discomfort, especially in the morning. As the condition progresses, vision may worsen, leading to significant visual impairment.
The disease typically develops in adulthood, with symptoms often appearing after the age of 50. However, in some cases, Fuchs Dystrophy can affect younger individuals.
Progression of Fuchs Dystrophy
Fuchs Dystrophy progresses slowly over time, and its severity can vary among individuals. Initially, the endothelial cells begin to lose their ability to pump excess fluid out of the cornea, causing the cornea to swell. As a result, vision becomes progressively blurred or hazy.
As the disease advances, tiny blisters, known as corneal guttae, may develop on the inner layer of the cornea. These guttae can rupture, leading to further corneal swelling and the formation of corneal scars. These changes can significantly impact vision, causing glare and sensitivity to bright lights.
If left untreated, Fuchs Dystrophy can ultimately result in corneal decompensation, a condition characterized by severe corneal clouding and vision loss.
