(2). Dislocation of eyeball from inflammation in Orbital Cavity.
53. (a) Septic infection from the lathi-wound.—The supraorbital fora-
mina in the camel are placed close together in the middle line ; the supraor-
bital vessels run through the frontal sinus in a bony tube ; the supraorbital
vein is directly continuous with the facial vein, and the fellows of opposite
sides are also joined by a small branch over the bridge of the nose near the
foramina.
A gangrenous lathi-wound sometimes causes septic phlebitis in the nasal
branch of facial vein and the inflammation progresses up the vein until the
supraorbital foramina are reached and thence passes into the orbital cavity
behind the eye and also to the vein of opposite side. Prom the resulting
inflammation the eyeball is pushed out of its socket and destroyed, and this
may occur on both sides before death which occurs from infection of the brain
through the various orbital foramina.
The symptoms before brain-infection are diffuse swelling over the nasal
and frontal regions, oedema of temporal fossa, dislocation of eyeball (one or
both) over the lower lid and a gangrenous state of the lathi-wound. The facial
vein " pointed " like an abscess in one case but contain only putrid clots and
no circulating blood.
The condition is preventable but not curable.
(5) Abscess behind eye.—A camel was examined post mortem which had
lost one eye from dislocation four or five months previously and still had a
swelling over the temporal fossa on the date that it died (of Surra). Brain-
infection had not taken place as the abscess was high up under the frontal
plate in the orbital cavity ; it was as big as a small apple and surrounded by
chronic inflammatory tissue. The frontal bone was depressed as if by a bite
and part of the frontal sinus injured.
54. (3) "Discharge of pus from the ear is fairly common in camels
and when unaccompanied by any swelling in the temporal fossa is local and
curable by suitable injections and thorough daily dressings and seems to be
due in the first place to slight wounds from thorns or bites, the thick discharge
from which has accumulated in the meatus and resulted in ulceration in the
meatus.
Pus in the temporal fossa tends to burrow backwards and find its way out
in or near the ear.
55. (4) Pus in the frontal sinus.—I have not yet met with this con-
dition, but there is evidence that it occurs and that absorption of bone follows
as the pus is too thick to escape through the small slit opening into the nose.
56. SURRA IN HOUSE.—The result of the treatment of a naturally acquired
case of Surra in a mare by Holmes' method has been communicated to him.
