In Colombia and throughout the world we know how to define keratoconus. We diagnose it with an excellent precision, usually without the aid of the corneal topography. With a test of queratometría, the professionals of the visual and ocular health can observe inductive nonclear sights of keratoconus that is a corneal degeneration of idiopatic cause. To say that its origin is hereditary, can be as false as to say that its origin is metabolic. What do we know for sure? Much and nothing at all. The only truth is that while in other countries its incidence and prevalence is well-known, in Colombia we do not have registered data officially. The registry is subclinical, because although it exists between the international classifications of the diseases, version 10, as clinical pathology, the professionals of the visual health and ocular normally do not register it. The objective of this article is to present a general revision of this pathology.
