Etymology: Gk, a + ops, not eye
a blindness resulting from a defect in or the absence of one or both eyes.
anopia(ă-nō′pē-ă) [ ¹an- + -opia]
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.
