or complete loss of sight. The eye appears to be fuller, brighter and 

 more brilliant than usual, and at the first glance, it seems a beautifully 

 developed eye. When it occurs, both eyes are affected, as a rule. In 

 the majority of cases, the horse carries his head well up, and steps 

 very high, in a hesitating, jerky manner. On carefully examining the 

 eye, the pupillary opening is very much dilated, and instead of being 

 elliptical, it is nearly circular, very little of the iris being seen ; whilst 

 on being subjected to the rays of a strong light, the pupil will not 

 contract. Detection of amaurosis, is really of more importance in 

 examination for soundness, than that of cataract. 



638. Filaria Oculi, or worm in the eye, is extremely rare in this 

 country, but is frequently seen in hot chmates, e.g., India. The parasite 

 is the strong ylus filavia, and measures from half to one inch long ; it is 

 found in the anterior chamber of the eye, where it moves about freely, 

 setting up irritation, and giving to the aqueous humour a peculiar 

 milky hue. It can be successfully removed by casting the horse, and 

 cutting into the eye at the upper edge of the cornea, so liberating the 

 humour, and with it, the offending worm. 



639. There are several other diseases of the eye, such as Nebula, 

 Glaucoma, Staphyloma, Tuberculosis, S'C, but as they are of rare 

 occurrence, I will not dwell upon them. 



640. Dislocation of the Eyeball is mostly seen in the dog, as 

 a result of fighting. When recently done it is readily reduced, by 

 pressing it carefully back into the socket with the thumbs, pulling tlie 

 lids forward with a pair of forceps, and keeping it in its place with a 

 bandage and a pad of wet lint. When it has been displaced for some 

 time, and has become swollen and congested, it should be bathed well 

 with tepid water, or an infusion of poppy heads ; and it may be necessary 

 to slit the eyelids at the outer corner, before returning it ; then it 

 should be maintained in its place by one or two stitches of antiseptic 

 thread, all being covered with a lint pad made wet with boracic lotion 

 (par. 529) and secured in its place with a bandage. In some cases, 

 the eveball is so much damaged that it has to be removed.
