In consequence of inflammation, the eyeball will sometimes become more than double its natural size. It will be cloudy, the different parts of it confused, and the sight gone. Nothing should be attempted to be done, except the dog is evidently suffering much pain from the distension of the eye, and then it may be punctured with a lancet, and the fluid evacuated. It is seldom that much inflammation follows this operation, nor does the dag express any great degree of pain, but the eye will afterwards dwindle almost entirely away.
