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 should not be confused with its opposite, exophthalmos, which is the anterior displacement of the eye.
The ptosis from inactivation of the superior tarsal muscle causes the eye to appear sunken in, but when actually measured, enophthalmos is not present. The phenomenon of enophthalmos is seen in Horner's syndrome in cats, rats, and dogs. [5] Sometimes there is flushing on the affected side of the face due to dilation of blood vessels under the skin.
In medicine, enophthalmia describes eyes that are abnormally sunken into their sockets. [1] This condition usually affects elderly persons.Surgery can be done to correct it. Bilateral progressive enophthalmos may be the presenting sign of metastatic breast carcinoma, even when local symptoms in the breast are absen
Enophthalmos in Horner's syndrome is an illusion created by the subtle ptosis of the upper eyelid caused by paralysis of the superior tarsal muscle. [ 7 ] Sinking in of the eye (true enophthalmos ) is possibly caused by paralysis of the smooth (orbitalis) muscle in the floor of the orbit.
In mild disease, patients present with eyelid retraction. In fact, upper eyelid retraction is the most common ocular sign of Graves' orbitopathy. This finding is associated with lid lag on infraduction (Von Graefe's sign), eye globe lag on supraduction (Kocher's sign), a widened palpebral fissure during fixation (Dalrymple's sign) and an incapacity of closing the eyelids completely ...
Eyes displaced posteriorly into sockets (enophthalmos) Limitation of eye movement (restrictive strabismus) Loss of sensation (hypoesthesia) along the trigeminal (V2) nerve distribution; Seeing-double when looking up or down (vertical diplopia) Orbital and lid subcutaneous emphysema, especially when blowing the nose or sneezing
Chronic progressive external ophthalmoplegia (CPEO) is a type of eye disorder characterized by slowly progressive inability to move the eyes and eyebrows. [1] It is often the only feature of mitochondrial disease, in which case the term CPEO may be given as the diagnosis.
Anophthalmia (Greek: ἀνόφθαλμος, "without eye") is the medical term for the absence of one or both eyes. Both the globe and the ocular tissue are missing from the orbit. [ 1 ] The absence of the eye will cause a small bony orbit, a constricted mucosal socket , short eyelids , reduced palpebral fissure and malar prominence . [ 2 ]
