Purulent Inflammation of the Eye (Panophthahjiitis). — This is 

 produced by serious concussion of the eye itself. It may also be due to 

 septic wounds of the cornea and sclerotic membrane, as well as to the 

 large perforating ulcers of the cornea. "We recognize the following 

 acute symptoms: 



The eyelids are constantly closed; great redness of the conjunctiva; 

 total opacity of the cornea; purulent accumulations in^the anterior 

 chamber of the eye (hypopyon) ; great hardness and enlargement of the 

 bulbus. After a short time we may have perforation through the cornea, 

 and, in rare cases, through the sclerotic membrane. The lens and vitre-

ous humor are ejected through the opening with the purulent mass; the 

 eyeball collapses, becomes contracted, and forms a knob-shaped mass in 

 the eye; the lids completely collapse and form a hollow in the face. The 

 only thing to do in such a case is to perform enucleation, or removal of 

 the eye. See Removal of EyelDall. 



Glaucoma and Hydrophthalmus. Dropsy of the Anterior Chamber. — 

 It is impossible to draw a distinct line between these two conditions. 

 The anterior chamber is very much enlarged, hard and tense, so much 

 so that the eyelids cannot be closed (goggle eye, exophthalmus). The 

 blood vessels of the conjunctiva and the sclerotic membrane are injected, 

 the cornea more or less opaque, the pupil much contracted and greenish 

 in color, insensibility of the cornea, and dilatation of the pupil. The 

 animal has partial or total loss of eyesight, congestion of the conjunctiva,
