Enophthalmos

Enophthalmos

Enophthalmos is the posterior displacement of the eyeball within the orbit due to changes in the volume of the orbit (bone) relative to its contents (the eyeball and orbital fat), or loss of function of the orbitalis muscle.[1] It should not be confused with its opposite, exophthalmos, which is the anterior displacement of the eye.

It may be a congenital anomaly, or be acquired as a result of trauma (such as in a blowout fracture of the orbit), Horner's syndrome (apparent enophthalmos due to ptosis), Marfan syndrome, Duane's syndrome, silent sinus syndrome or phthisis bulbi.
