bo CAUSES, f^YMPTO.MK AND TREATMENT Of 



(glaucoma, —If there is either amaurosis or cataract, you have this 

 condition present, but you may me6t with a case where this is seen with- 

 out any other disease. The vitreous humour becomes hardened, more or 

 Jess, and a dilated pupillary opening ; big head or ostero sai'coma has a 

 tendency to profluce it. Little, if anything, can be done for it. If it is 

 in an old animal from natural decay, as is generally the case, nothing can 

 be done. The eye ball is occasionally injured, frequently from a punc- 

 tured wound, and letting the aqueous humour escape. If the vitreous 

 humour or crystalline lens escapes, vision is totally destroyed. The 

 aqueous humour will be reproduced, but there may remain a slight 

 opacity of the cornea. 



Treatment must vary as to the severity of the injury. If a punc- 

 ture is received and the crystalline lens is injured there will be 

 great pain present Foment, use belladona, give a purgative, and 

 may give an opiate ; poultice judiciously with linseed meal, bread 

 poultice, etc You may tind a fungus growth, from puncture or 

 other injury, and you can generally get rid of it with a solution 

 of nitrate of silver. But this may not be strong enough, and you 

 will have to touch with a pencil of nitrate of silver. After this you 

 may have a small speck, and if there is exudation around the speck, 

 you may relieve by judicious stimulation. In some diseases or in- 

 juries to the eye, the parts do not heal up, a discharge of matter 

 takes place, and it is better in some cases to remove the tissue 

 of the eye Another condition of the eye-ball is dislocation, more 

 likely to occur in dogs than in other animals, from fighting with 

 other dogs and cats. If it does occur in the horse, the tissues are 

 generally lacerated. If you see such a case soon after its occurrence, 

 the eye may be replaced and remain placed, if done before the swelling is 

 too great. After replacing, apply fomentations, as to other injuries to 

 allay irritation But if it is down over the cheek and much swollen, the 

 only thing that can be done is to remove the eyeball, and treat as an 

 injury. If it requires much pressure upon the eyeball to replace it, you 

 can just snip the outer angle of the eyelid, and after the ball is replaced 

 just put a stitch in the cut and then use something to allay irritation. 

 Melanotic deposits may take place in the eye. They are commoner in 

 gray horses than others, but may occur in any, and they may occur in any 

 part of the body ; if in the eye, there is a reddened condition of the eye. 

 Nothing whatever can be done for this. 



Ectropium or Eversion of the Eyelids , Entrnpium or Inversion 

 of the Eyelids. — Eyelids become torn and injured in many ways. If 

 you find the lid torn and injured be as conservaiive as you can and bring 

 the parts together nicely, using a suture of silk thread or wire. Although 

 it is prettv well detached, bring the parts together the best you can and 

 do not allow any part to hang down, or it will bring on suppuration, and 

 if any part is removed, it interferes with the animal to some extent. 



After-Treatment. — Allay any irritation. Keep the animal quiet, and 

 secure him so as to keep him from rubbing, by tying to both sides of the 

 stall Keep up the application of either cold or warm water, but cold 

 water generally has a better effect than warm. There will be more or 

 less opacity of the cornea, but when the irritation is allayed, the opacity 

 will disappear. If a large portion of the lid is torn loose and nothing has 

 been done for it until suppuration has taken place, and it is much swol- 

 len, then scarify and treat properly, and there is a possibility of recovery. 

 In some cases you will have to remove the partially detached portions, 

 but do not be too hasty about cutting.
