Congenital no iris

Aniridia is a developmental disorder in both eyes. It is mainly characterized by congenital dysplasia or the absence of normal iris. It can also be accompanied by a variety of eye diseases such as corneal opacity, small cornea, lens dislocation, cataract, glaucoma, Macular dysplasia, strabismus, nystagmus, etc., affect the whole eye. Some comorbidities already exist at birth, while others can extend into childhood or early adulthood. There are also some patients with systemic abnormalities. But the term "no iris" is actually a misnomer, because there is still the root of the iris and there is no iris-free.
