We know from keratoconus the progressive deformity of the most frequent cornea, which happens when it becomes thinner and acquires a conical and irregular shape. It has an incidence of one person every 2,000 and we can locate the beginning of this pathology during the years of puberty.
Regarding its causes, an autosomal dominant transmission with incomplete penetration has been proposed, which would affect only 10% of patients. The combination of intrinsic factors that destroy collagen and other environmental extrinsic factors, such as trauma or rubbing, are considered in the pathogenesis of the disease.
We must start from the basis that keratoconus is not an aesthetic problem. The progressive reduction of vision is one of the greatest risks of the pathology, which can lead to a corneal thinning and irregular astigmatism.
This progressive loss of vision is painless in the most common cases of keratoconus, although acute keratoconus or corneal Hydrops may occur, in which the aqueous humor enters the interior of the cornea due to rupture of the internal layer of the cornea. case associate with a painful picture.
How to correct it
The problem of keratoconus, in early cases, can be corrected by wearing glasses. In more advanced cases, with higher astigmatism, rigid contact lenses are the appropriate treatment.
