Glioma óptico - Información general

Nombres alternativos

Glioma de los ojos; Glioma del nervio óptico

Definición:

Los gliomas son tumores que crecen en varias partes del cerebro. Los gliomas ópticos pueden afectar:

  • Uno o ambos nervios ópticos que son los nervios que llevan la información visual al cerebro desde cada ojo.
  • El quiasma óptico, el área donde se entrecruzan los nervios ópticos en frente del hipotálamo del cerebro.

Un glioma óptico también puede crecer junto con un glioma hipotalámico.

Causas, incidencia y factores de riesgo:

Los gliomas ópticos son raros y su causa se desconoce. La mayoría de estos gliomas son de crecimiento lento y no cancerosos ( benignos), y ocurren en niños, casi siempre antes de los 20 años.

Existe además una fuerte asociación entre el glioma óptico y la neurofibromatosis tipo 1 (NF1).
