Anophthalmos is the medical term for congenital (i.e. from birth) absence of an eye.
Both eyes, or just one eye, may be affected.
There are three classifications of anophthalmos:
- Primary Anophthalmia is a complete absence of eye tissue due to a failure of the part of the brain that forms the eye. This is extremely rare.
- Secondary Anophthalmia refers to the situation when the eye started to develop and then for some reason ceased development - resulting in only residual eye tissue or very tiny eyes that can only be seen under close examination. This is less rare than "Primary Anophthalmia".
- Degenerative Anophthalmia refers to the situation when the eye started to form and then for some reason degenerated, e.g. due to lack of blood supply to the developing eye.
There is no known cure for anophthalmos but treatment may involve use of prosthetic eyes fitted to the empty eye sockets both for cosmetic purposes, and also to help promote growth of the eye socket.
