Abstract

Keratoconus is an asymmetric bilateral corneal ectasia, in early stages binocular involvement is not evident. Knowledge of the degree of asymmetry in pediatric keratoconus allows timely decisions in patient management. This research was carried out with the objective of describing the clinical characteristics and the treatment of three pediatric cases with different degree of interocular asymmetry of keratoconus, treated in the provincial consultation of pediatric corneal ectasia in Ciego de Avila. Patients showed difference between both eyes in clinical signs, refraction and topographic variables. Patient two was diagnosed with keratoconus in one eye, with no clinical or topographic evidence of the disease in the contralateral eye. All patients showed compound myopic astigmatism in both eyes and optical correction was indicated. Patient one was corrected with glasses, patient two with rigid gas permeable contact lenses and patient three with piggyback in one eye and rigid gas permeable contact lenses in the other eye. They also presented an associated amblyopia and were directed occlusive treatment and near vision tasks in patients two and three. It is common to find interocular asymmetry in pediatric patients with keratoconus due to the difference in progression between the two eyes. Periodic follow-up makes it possible to diagnose the disease in the contralateral eye in patients diagnosed with keratoconus in one eye, to indicate individualized optical correction, especially in the presence of anisometropia, and to monitor the evolution of frequently associated refractive amblyopia.
