Entropión - Overview

Definición:

Es la inversión de los bordes del párpado (generalmente el párpado inferior) de forma tal que las pestañas se rozan con la superficie del ojo.

Causas, incidencia y factores de riesgo:

El entropión puede estar presente al nacer (congénito).

Aunque es poco frecuente en América del Norte y Europa, la infección por tracoma puede ocasionar cicatrización del lado interno del párpado, lo cual puede causar entropión. La cicatrización por tracoma es una de las tres primeras causas de ceguera en el mundo.

Los factores de riesgo que predisponen al desarrollo de entropión abarcan:
