Anophthalmia refers to a complete absence of ocular development. It is often considered to represent the most severe form of microphthalmia.
It can occur in 3 different situations:
- primary anophthalmia: complete absence of eye tissue due to a failure of the part of the brain that forms the eye.
- secondary anophthalmia: there is initial eye developent which halts for some reason leaving behind only residual eye tissue or extremely small eyes which can only be seen under close examination.
- degenerative anophthalmia: there is initial ocular development but again for some reason starts to degenerate - possibly from lack of blood supply to the eye.
Recognised associations are many and include:
It derives from the Greek word : ανόφθαλμος meaning "without eye"
