Blefaroespasmo - Overview

Nombres alternativos

Espasmo del párpado; Contracción del ojo; Contracción del párpado

Definición:

Es un término general para los espasmos involuntarios de los músculos del párpado. En algunos casos, el párpado puede cerrarse (o casi cerrarse) de manera repetitiva y luego volver a abrirse.

Este artículo aborda los blefaroespasmos en general.

Causas, incidencia y factores de riesgo:

Las cosas más comunes que pueden causar espasmos en el músculo del párpado son fatiga, estrés y la cafeína. Una vez que empiezan los espasmos, pueden continuar de manera intermitente por algunos días y luego desaparecen. La mayoría de las personas experimenta este tipo de blefaroespasmo ocasionalmente y lo califica de muy molesto. En la mayoría de los casos, usted ni siquiera nota cuando se detienen.

Son posibles las contracciones más severas, con cierre completo de párpado, que pueden ser causadas por irritación de la superficie del ojo (córnea) o de las membranas que recubren los párpados (conjuntiva).

Algunas veces, no se puede identificar la causa de las contracciones del párpado. Esta forma de espasmo del párpado dura mucho más tiempo, es a menudo bastante molesta y también puede causar el cierre completo de los párpados.
