Enophthalmos is a posterior displacement of the eyeball within the orbit. It is due to either enlargement of the bony orbit and/or reduction of the orbital content, this in relation to each other.[1]

It may be a congenital anomaly, or be acquired as a result of trauma (such as in a blowout fracture of the orbit),[2] Horner's syndrome (apparent enophthalmos due to ptosis),[3] Marfan syndrome, Duane's syndrome, silent sinus syndrome or phthisis bulbi.[4][5][6]
