Risk factors for amblyopia in congenital anterior lens opacities.

Purpose: We sought to identify the features of congenital anterior lens opacities (CALOs), which are associated with increased risk for amblyopia.

Methods: We undertook a retrospective study of 59 patients with CALO from 3 clinical practices. The following variables were examined: type (polar, subcapsular, or pyramidal), location (central, paracentral, or peripheral), diameter, presence of adherent iris tissue, anisometropia (spherical equivalent), unilateral versus bilateral, and presence or absence of amblyopia.
