Soldiers have been seen to drop lifeless on the battle…field without apparent injury or organic derangement； in the olden times this death was attributed to fear and fright； and later was supposed to be caused by what is called 〃the wind of a cannon…ball。〃 Tolifree has written an article on this cause of sudden death and others have discussed it。 By some it is maintained that the momentum acquired by a cannon…ball generates enough force in the neighboring air to prostrate a person in the immediate vicinity of its path of flight。
CHAPTER X。
SURGICAL ANOMALIES OF THE HEAD AND NECK。
Injuries of such a delicate organ as the eye； in which the slightest accident can produce such disastrous consequences； naturally elicit the interest of all。 Examples of exophthalmos； or protrusion of the eye from the orbit from bizarre causes； are of particular interest。 Among the older writers we find Ficker and the Ephemerides giving instances of exophthalmos from vomiting。 Fabricius Hildanus mentions a similar instance。 Salmuth； Verduc； and others mention extrusion of the eyeball from the socket； due to excessive coughing。 Ab Heers and Sennert mention instances in which after replacement the sight was uninjured。 Tyler relates the case of a man who； after arising in the morning； blew his nose violently； and to his horror his left eye extruded from the orbit。 With the assistance of his wife it was immediately replaced and a bandage placed over it。 When Tyler saw him the upper lid was slightly swollen and discolored； but there was no hemorrhage。
Hutchinson describes extrusion of the eyeball from the orbit caused by a thrust with a stick。 There was paraphymotic strangulation of the globe； entirely preventing replacement and necessitating excision。 Reyssie speaks of a patient who； during a fire； was struck in the right eye by a stream of water from a hose； violently thrusting the eye backward。 Contracting under the double influence of shock and cold； the surrounding tissues forced the eyeball from the orbit； and an hour later Reyssie saw the patient with the eye hanging by the optic nerve and muscles。 Its reduction was easy； and after some minor treatment vision was perfectly restored in the injured organ。 Thirty months after the accident the patient had perfect vision； and the eye had never in the slightest way discommoded him。
Bodkin mentions the case of a woman of sixty who fell on the key in a door and completely avulsed her eye。 In von Graefe's Archiv there is a record of a man of seventy…five who suffered complete avulsion of the eye by a cart…wheel passing over his head。 Verhaeghe records complete avulsion of the eye caused by a man falling against the ring of a sharp…worn key。 Hamill describes the case of a young girl whose conjunctiva was pierced by one of the rests of an ordinary gas…bracket。 Being hooked at one of its extremities the iron became entangled in either the inferior oblique or external rectus muscles； and completely avulsed the eyeball upon the cheek。 The real damage could not be estimated； as the patient never returned after the muscle was clipped off close to its conjunctival insertion。 Calhoun mentions an instance of a little Esquimaux dog whose head was seized between the jaws of a large Newfoundland with such force as to press the left eyeball from the socket。 The ball rested on the cheek； held by the taut optic nerve； the cornea was opaque。 The ball was carefully and gently replaced； and sight soon returned to the eye。
In former days there was an old…fashioned manner of fighting called 〃gouging。〃 In this brutal contest the combatant was successful who could； with his thumb； press his opponent's eyeball out。 Strange to say； little serious or permanently bad results followed such inhuman treatment of the eye。 Von Langenbeck of Berlin mentions an instance of fracture of the superior maxilla； in which the eyeball was so much displaced as to lodge in the antrum of Highmore。 Von Becker of Heidelberg reports the history of a case in which a blow from the horn of a cow dislocated the eye so far back in the orbit as to present the appearance of enucleation。 The conjunctiva hid the organ from view； but when it was pulled aside the eyeball was exposed； and in its remote position still possessed the power of vision。 In some cases in which exophthalmos has been seemingly spontaneous； extreme laxity of the lids may serve as an explanation。 There is an instance on record in which a Polish dew appeared in a Continental hospital； saying that while turning in bed； without any apparent cause； his eyeball was completely extruded。 There have been people who prided themselves on their ability to produce partial exophthalmos。
Rupture of the Eyeball。Jessop mentions the case of a child of eight who suffered a blow on the eye from a fall against a bedpost； followed by compound rupture of the organ。 The wound in the sclerotic was three or four lines in length； and the rent in the conjunctiva was so large that it required three sutures。 The chief interest in this case was the rapid and complete recovery of vision。
Adler reports a case of fracture of the superior maxillary in which the dislocated bone…fragment of the lower orbital border； through pressure on the inferior maxillary and counter pressure on the skull； caused rupture of the conjunctiva of the left eye。
Serious Sequelae of Orbital Injuries。In some instances injuries primarily to the orbit either by extension or implication of the cerebral contents provoke the most serious issues。 Pointed instruments thrust into the orbital cavity may by this route reach the brain。 There is a record of death caused by a wound of a cavernous sinus through the orbit by the stem of a tobacco…pipe。 Bower saw a woman at the Gloucester Infirmary who had been stabbed in the eye by the end of an umbrella。 There was profuse hemorrhage from the nostrils and left eye； but no signs indicative of its origin。 Death shortly ensued； and at the necropsy a fracture through the roof of the orbit was revealed； the umbrella point having completely severed the optic nerve and divided the ophthalmic artery。 The internal carotid artery was wounded in one…half of its circumference at its bend； just before it passes up between the anterior clinoid process and the optic nerve。 The cavernous sinus was also opened。 In this rare injury； although there was a considerable quantity of clotted blood at the base of the brain； there was no wound to the eyeball nor to the brain itself。
Pepper records a case in which a knife was thrust through the spheroidal fissure； wounding a large meningeal vein； causing death from intracranial hemorrhage。 Nelaton describes an instance in which the point of an umbrella wounded the cavernous sinus and internal carotid artery of the opposite side； causing the formation of an arteriovenous aneurysm which ultimately burst； and death ensued。 Polaillon saw a boy of eighteen who was found in a state of coma。 It was stated that an umbrella stick had been thrust up through the roof of the orbit and had been withdrawn with much difficulty。 The anterior lobe of the brain was evidently much wounded； an incision was made in the forehead and a portion of the frontal bone chiseled away entran
