They are a group of diseases that are characterized by progressive loss of transparency of the cornea, without the existence of inflammation. When it loses its transparency, there is a decrease in vision of variable degree depending on the extension of the affected area and they are of genetic origin. The first symptoms can appear between the ages of 10 and 40 and are bilateral, that is, they affect both eyes and evolve slowly and progressively.
Treatment: If you do not have any symptoms, your eyes should be watched closely to see if the disease is progressing. In other cases, artificial tears, ointments, or laser treatment may be appropriate and prevent repeated corneal erosions. This condition can be treated with a) antibiotics b) lubricating drops c) ointments d) soft contact lenses. If erosion continues, other treatment options may include the use of laser therapy or a technique to scrape the cornea. In the most severe cases, a corneal transplant may be necessary. For endothelial dystrophies, such as Fuchs' dystrophy, a partial corneal transplant (called endothelial keratoplasty) is used.
