Iris Growing Over A Pupil
This genetic disorder produces tissues most times a strand of tissues that crosses the pupil. Now this becomes problematic to the fetus because it uses the pupillary membrane as a source of blood supply for the lens. Although a single strand wastes away after birth between the age of 4 to 8 weeks. Only large strands may disrupt the vision and a minimal amount of membrane tissue is considered non-harmful.
