[Pseudokeratoconus and ocular rosacea].

Photokeratoscopy analysis of the anterior curve of the cornea can detect keratoconus, particularly in the early stages of the disease. Nevertheless, all irregular astigmatisms are not related to keratoconus. We report here several cases of patients presenting high asymmetric astigmatism with features of keratoconus, although the clinical examination suggests corneal disease related to rosacea.
