A newborn child with aniridia closes its eyes when facing a light source and feels more comfortable in semidarknes. Because of this, the child should be taken to an ophthalmologist to determine the degree of the disease and to be informed about other associated disorders and the examinations the child should undergo. Regarding this, the child should see the ophthalmologist every three to six months during his first few years. From then on, at least once a year.
