[Keratotorus. Aetiology with regard to heredity (author's transl)].

We describe the biggest group of toric deformation of the cornea reported up to now. We point out in particular two ribs whose parents are blood-related. Hence we obtained the first evidence for an inheritance (autosomal recessive) of this corneal anomaly. The term Keratotorus is recommended as the best definition for this toric corneal deformation. Although there are similarities with other anomalies of curvature of the cornea, the clinical picture of keratotorus can be seen also in the future as a nosological entity.
