    is there a difference between proptosis and exophalmos?

    proptosis: abonormal protrusion of an organ, especially the eyeball
    exophalmos: protrusion of the eyeballs in their socket

    same or different?

    I was under the impression that exopthalmos was the term used to describe proptosis (protruding eyes) as a result of endocrinological disorder.

    Spooky we were talking about this the other day before my clinical exams, trying to work out what the difference was before examining the thyriod
    Proptosis is the forward displacment of an organ (not specifically the eye)
    Exopthalmos is protrusion of they eyebll in their sockets from disease or injury.

    Love medical dictionaries

    difference between exopth.&proptosis

    hi the diffference between them lies in the cause /etiology
    exopthalmos is a term used for forward displacement of the eyeball due to an endocrinal cause as Grave's disease(autoimmune disease)

    proptosis is a term used when other causes exist as
    inflammatory(periostitis/orbital cellulitis/tennonitis/cavernous sinus thrombosis)
    traumatic(iatrogenic or non-iatrogenic)
    tumors(benign &malignant as rhabdomyosarcoma/retinoblastoma/craniopharyngioma)

    hope it has been a help
    bye

    But as i said Proptosis can be applied to any organ that has been caused to move forwards.
    I.e. the gall bladder due to a large tumour behind.

    Furthermore

    In the context of thyroid examination:

    Proptosis - the eye has protruded so far forward that it is visible beyond the level of the supraorbital ridge when looking over the head of the patient from behind

    Exophthalmos - both eyelids move away from the centre of the iris so that the whiteness of the sclera is visible below or all around the iris

    Epstein's clinical examination defines propotosis as exophthalmos > 16mm (exophthalmos is propotosis >16mm, well anyway, it's one of the two in that book).
