Cornea guttata and Fuchs dystrophy


Cornea guttata and Fuchs dystrophy

What is it?

The human cornea is a transparent tissue consisting of five layers, about 550 microns thick (0.55mm). It corresponds to the first lens of the eye’s optical system.

The cornea guttata and Fuchs' dystrophy are two conditions that affect the deepest layer of the cornea; the endothelium and its cells are responsible for maintaining corneal transparency. They occur frequently and have different medical assessment. Fuchs Dystrophy generally results from the progress of the first.


The most noticeable symptoms are those derived from corneal thickening and loss of transparency, edema and pain in some cases. The vision may be compromised in more severe cases, with loss of sharpness in the perception of images, more pronounced in the morning.


Symptoms can be treated with eye drops or antiedemal ointment, but the solution is the posterior lamellar corneal transplant in which a healthy endothelium is transplanted from a donor. In this way, the placing of a new cell layer on the back of the cornea is achieved, to correctly perform their biological functions, restoring transparency in corneal tissue.


The cornea guttata in many cases will be an unexpected finding. However, Fuchs dystrophy can be inherited from parents or can occur sporadically. It is recommended to perform a full annual eye exam. In addition, special care should be taken for planning cataract surgery if are these two pathologies are present.
