Síndrome de Horner - Overview

Definición:

Es un raro trastorno que afecta los nervios que van al ojo y a la cara.

Causas, incidencia y factores de riesgo:

El síndrome de Horner puede ser causado por cualquier interrupción en una serie de fibras nerviosas que comienzan en la parte del cerebro llamada hipotálamo y van hasta la cara.

Las lesiones a las fibras nerviosas simpáticas pueden ser el resultado de:

Lesión a una de las principales arterias que van al cerebro (arteria carótida)
Lesión a los nervios en el cuello llamado plexo braquial
Migraña o cefaleas en brotes
Accidente cerebrovascular, tumor u otro daño a la parte del cerebro llamada el tronco del encéfalo
Tumor en la parte superior del pulmón

En contados casos, el síndrome de Horner puede estar presente en el momento de nacer (congénito). La afección puede ocurrir con una falta de color (pigmentación) del iris (parte coloreada del ojo).
