Subclinical Keratoconus

Abstract

A clinical case is reported of a patient attending consultation with an optical prescription of myopic astigmatism in both eyes. The optometric examination does not reveal any significant variation in the existing optical correction. Three years later, the patient has a decreased visual acuity, a slight increase in corneal curvature and in the diopter value of the sphere and cylinder in both eyes, as well as variation in one axis (15 degrees). Previous findings justified requesting supplementary tests that could explain the modifications found in visual and ocular conditions in the period between the two controls. Complementary clinical testing (Pentacam) made it possible to determine the presence of a subclinical keratoconus.
