Aniridia
Aniridia is the medical term used in ophthalmology to refer to the congenital (i.e. since birth) partial or complete absence of the iris of an eye.
It is a binocular condition, meaning that both eyes are usually affected.
Aniridia is a rare condition that does not always cause lack of vision, but often leads to a number of secondary ophthalmic conditions such as low vision, glaucoma, cataracts, etc..
