Protuberant eyes, or exophthalmos, can be a sign of a thyroid disorder, for example.
Excessive thyroid secretion, as in thyrotoxicosis from functioning adenomata, and excessive thyroid feeding, cause all the phenomena of Graves 'disease except the exophthalmos and the emotional facies (Figs. 15 and 23).
It is "a fact that forcible expiratory efforts in violent coughing or vomiting, and especially in sneezing, sometimes give rise to ruptures of the little (external) vessels" of the eye. 17 With respect to the internal vessels, Dr. Gunning has lately recorded a case of exophthalmos in consequence of whooping-cough, which in his opinion depended on the rupture of the deeper vessels; and another analogous case has been recorded.
In some cases in which exophthalmos has been seemingly spontaneous, extreme laxity of the lids may serve as an explanation.
Examples of exophthalmos, or protrusion of the eye from the orbit from bizarre causes, are of particular interest.
Holmes also reports a case of enormous congenital exophthalmos, in which the right eye protruded from the orbit and was no longer covered by the cornea.
There have been people who prided themselves on their ability to produce partial exophthalmos.
For twenty-four years he had suffered from cephalalgia and pains and partial exophthalmos of the left eye.
Among the older writers we find Ficker 10.1 and the Ephemerides giving instances of exophthalmos from vomiting.
