Abstract

Corneal edema and decreased endothelial cell count are complications related to chronic low-grade hypoxia experienced by contact lens wearers, primarily due to prolonged and overnight wear. This case shows the example of a patient who has blurred vision problems in both eyes and who underwent a complete ophthalmologic examination that included photographs, corneal topography and endothelial cell count. Subsequently, the corneal metabolism, the etiopathogenesis and the complications derived from the use of contact lenses are reviewed.

Keywords:

Resumen

El edema corneal y la disminución del recuento de células endoteliales son complicaciones relacionadas con la hipoxia crónica de bajo grado que experimentan los usuarios de lentes de contacto, principalmente debido al uso prolongado y nocturno. Este caso muestra el ejemplo de un paciente que presenta problemas de visión borrosa en ambos ojos y a quien se le realizó un examen oftalmológico completo que incluyó fotografías, topografía corneal y conteo de células endoteliales. Posteriormente se revisa el metabolismo corneal, la etiopatogenia y las complicaciones derivadas del uso de lentes de contacto.
