What is Fuchs dystrophy and why does it appear?

Fuchs dystrophy can be very disabling, as it ends up producing continuous blurred vision. Therefore, it is necessary to treat it.

Fuchs corneal dystrophy is a progressive, hereditary disease of the cornea that usually appears between 50 and 60 years of age. According to information from Expert Review of Ophthalmology, it is a condition of the posterior cornea that manifests itself with the loss of endothelial cell density.

In this disease, the endothelial cells inside the cornea fail or die progressively. The function of these cells, in addition to nourishing the cornea, is to prevent it from swelling. To do this, they remove the liquid from inside them into the aqueous humor.

In this way, the cornea remains thin and transparent. Therefore, when these cells lose functionality, the cornea becomes swollen and the rays cannot adequately impact the retina.

Although the exact cause of why this situation occurs is not known, it is believed that it has an important hereditary component. However, the genetic foundations are complex and there is not always a family history.

On the other hand, a series of factors have been identified that increase the risk of suffering from this condition. One of them, which we have already pointed out, is age. It most commonly begins in late adulthood.
