Heterocromía - Overview

Nombres alternativos

Ojos de diferente color; Ojos de colores diferentes

Definición:

Heterocromía es la presencia de ojos de diferente color en la misma persona.

Consideraciones generales:

La heterocromía es poco común en los seres humanos, pero bastante común en perros (como los dálmatas y los pastores australianos), gatos y caballos.

Causas comunes:

La mayoría de los casos de heterocromía son hereditarios, causados por una enfermedad o síndrome o debido a una lesión. Algunas veces un ojo puede cambiar de color después de ciertas enfermedades o lesiones. 

Las causas específicas son, entre otras:

  • Heterocromía familiar (transmisión autosómica dominante)
  • Síndrome de Waardenberg (congénito y autosómico dominante)
  • Algunos medicamentos utilizados para tratar el glaucoma pueden hacer que el iris (parte coloreada del ojo) se oscurezca
  • Neurofibromatosis que puede hacer que el iris afectado se oscurezca
  • Lesión, hemorragia (sangrado), glaucoma o un cuerpo extraño en el ojo
