Anophthalmic ptosis should never be considered as an entity in isolation, and in this regard it is unlike other forms of acquired ptosis. Surgical anophthalmia changes the relationship between the eyelids and the orbital contents. Furthermore, changes within the orbital soft tissue may secondarily manifest as ptosis. Conversely, lower lid laxity associated with anophthalmia may result in a downward displacement of the ocular prosthesis, resulting in masking of underlying ptosis. In all likelihood, the majority of anophthalmic ptosis is the result of multiple factors and must always be evaluated in relation to associated orbital and periocular soft tissues. Effective management of the ptotic lid in anophthalmia can be difficult and must take into account these orbital and periocular factors as well as prosthesis fitting.
