    Exophthalmos.—Protrusion of the Eye-hall. The term exophthalmos is generally applied to that protrusion of the eye-ball which is caused by one or more tumours growing in the socket. Some authors have included under this name also, that kind of protrusion which arises from some injury inflicted upon the muscles of the globe; but this is more properly styled Proptosis, or pro- cidentia of the eye-ball. When, on the other hand, the affection arises from disorganization of the globe itself, it is known under the denomination of Exophthalmia. Encysted tumours, forming at the bottom or sides of the orbit, most commonly give rise to exophthalmos. These tumours are in every re- spect analogous to those which occur in the cel- lular structure of other parts of the body, and contain, for the most part, a fatty or oleaginous matter; occasionally they are filled with a gluti- nous fluid, not unlike the white of an egg, and in some cases, they are seen to contain a limpid or sanious matter. Exophthalmos may be occasioned likewise by a collection of pus or hydatids in the orbit, or by exostosis of the bones adjacent to the eye-ball. The disease is frequently caused by fungous tumours arising in the antrum maxillare, the nasal fossae or frontal sinuses, which in their progress destroy the orbitary plates, and enter
