anophthalmia
Congenital absence of all tissues of the eyes. It is due to a failure of the outgrowth of the optic vesicle to form the optic cup. However, in many cases some development occurs and there is a rudimentary presence of one or both eyes, such as extreme microphthalmia. Syn. anophthalmos; anophthalmus; anopia. See optic cup; microphthalmia; monophthalmia; optic vesicle.
