DISEASES AND TEEATMENT OF THE HORSE. 155 



the eye. The eye has a hazy appearance and seems very weak, 

 and by watching it you can see the worm sometimes in the front, 

 then it will move around to the back. If the worm is allowed to 

 remain in the eye it will keep the eye irritated. 



Treatment. — The only thing- that can be done to save the eye 

 is an operation. Cast the animal and secure him, have his head 

 held solid so that he cannot move, take a small lance or sharp pen- 

 knife and make a small incision or cut across the sight of the eye, 

 which will let the humors of the eye run out, and with it the worm 

 generally comes. Keep the animal quiet after the operation and 

 put him in a clean, dark box stall for a few days. Bathe the eye 

 with new milk twice a day and apply the eye wash after bathing 

 until the eye is healed. It generally takes a week or so for the 

 eye to heal and the fluid to form in the eye. After the course of 

 two or three weeks all that will be noticed is a slight scar, which 

 will gradually absorb away in time and the eye will get all right. 



GLAUCOMA. 



This is a hardening of the back humor of the eye. 



Causes. — From a severe injury to the eye, or where the eye 

 is pierced by a stick or anything, and it injures the back part of 

 the eye ; or sometimes from natural decay in old animals. 



Symptoms. — The horse gradually gets blind, and has high, 

 peculiar action in front, the same as seen in all blind animals. 

 If you look into the eye through the pupil you will see that the 

 eye has become hardened and is of a grayish color. 



Treatment. — in a case where it comes on from an injury, 

 bathe with new milk three or four times a day, and apply, after 

 bathing, the eye wash. It is more frequently noticed in gray 

 horses than in others, and if it comes on in old ace nothino- 

 can be done to cure it. 



INFLAMMATION OF THE HAW OF THE EYE (MEMBRANA NICTITANS). 



This is the diseased or enlarged state of the cartilage in the 

 corner of the eye. 



Causes. — Generally from chaff or something getting into the 

 eye and irritating it. This causes it to enlarge and stick out of 

 the corner of the eye and gives the animal a great deal of trouble, 

 and also looks very bad. 



Treatment. — When it is first noticed remove the irritation, if 

 it can be found, and bathe with new milk or luke warm water two
