Ceguera nocturna
Definición:
Es la visión escasa en la noche o en ambientes con luz tenue.
Nombres alternativos:
NictalopÃa; NictanopÃa; Ceguera en la noche
Consideraciones generales:
La ceguera nocturna puede causar problemas para conducir un vehÃculo al final de la tarde o en la noche. Las personas que padecen este tipo de ceguera con frecuencia tienen problemas para ver las estrellas en una noche clara.
Causas comunes:
- Cataratas
- Retinitis pigmentaria
- Deficiencia de vitamina A
- Ciertas drogas
- Defectos congénitos
En algunos casos, los ojos simplemente pueden tener dificultad para adaptarse a la oscuridad y es posible que el problema no se deba a otra afección. Sin embargo, con frecuencia está ligada a la miopÃa (visión corta).
