A congenital corneal opacity is a rare occurrence but can cause significant visual compromise to the affected infant. Additional interventions during penetrating keratoplasty were moderately positively correlated with graft failure. In keratoconus, the central or paracentral cornea bulges and progressively thins such that the cornea takes on the shape of a cone. The genotyping literature of these conditions is littered with confusion. Not surprisingly, if the lens forms partially or fails to form, this has an effect on the vitreous and the drainage angle.
