Figure 1. Two important causes of treatable congenital blindness in the developing world.

The left panel shows a child with bilateral corneal opacities and the right shows dense congenital cataracts. Both of these conditions are treatable with simple surgical procedures (grafting clear donor tissue for corneal opacities; lens extraction followed by intra-ocular lens implantation for cataracts).
