Prevalence of anterior polar cataracts in children and risk factors for amblyopia.

Anterior polar cataract is a highly amblyogenic condition not because of a visually obstructing lens opacity but because of refractive errors, primarily hypermetropic anisometropia and astigmatism. Anterior polar cataract seems to represent an anomaly in global eye development resulting in reduced axial length. Patients with anterior polar cataract should be monitored to detect and treat amblyopia in time.
