Fuchs’ dystrophy, also known as Fuch’s endothelial dystrophy, is a condition that impacts the cornea – the transparent outer layer that safeguards the pupil and iris from potential harm, germs, and debris. The cornea’s epithelial tissue plays a vital role in maintaining clear vision. However, in Fuchs’ dystrophy, the endothelial cells comprising this tissue gradually deteriorate. Consequently, fluid accumulates within the cornea, leading to swelling and a subsequent decline in visual acuity.
Symptoms of Fuchs’ Dystrophy
Fuchs’ dystrophy typically impacts both eyes and gradually leads to a decline in vision. However, individuals usually do not experience noticeable symptoms until they reach the age of 50 or older. Late-onset Fuchs’ dystrophy, as stated by the National Institutes of Health, affects approximately 4% of individuals aged 40 and above, while early onset is uncommon. Here are some of the symptoms associated with this condition:
Diagnosing Fuchs’ Dystrophy
When it comes to diagnosing Fuchs’ dystrophy, an ophthalmologist plays a crucial role. They utilize various methods to assess the condition of the cornea and identify any potential issues. One of the primary techniques involves examining the cornea’s thickness and searching for the presence of small blisters that may appear on either the front or back surfaces. These blisters are responsible for the discomfort experienced by individuals with Fuchs’ dystrophy. Additionally, ophthalmologists may opt to capture specialized photographs of the cornea to analyze the number of remaining cells in the endothelium.
