DISEASES OF THE EYE 35 



REMEDIES. When this disease first makes its 

 appearance, the affected eye should have placed over 

 it a thin sponge saturated with belladonna lotion. 

 The horse should then be put upon a low diet, and 

 gentle purgatives administered. 



When the pain and inflammation have subsided, 

 if opacity of the lens has taken place (cataract), we 

 are not aware of any means of removing it and 

 restoring vision, except by an operation, as in the 

 human subject, and for obvious reasons it could not 

 be a practical success. 



THE HAW. 



It is no unusual thing for a thickening of this 

 part to take place, and it will then protrude itself on 

 the fore part of the eyeball. In this disease the 

 retractor muscle pulls back the eye to protect it from 

 the irritating effect of the light, and this thickening 

 of the haw pushing it forward, and the adjacent 

 parts being also thickened, no retraction can take 

 place. 



The practice of cutting out this is exceedingly 

 absurd, and ought never to be resorted to. It is 

 intended for protecting the eye against dust or 

 insects. In former times few farriers understood the 

 use of the haw ; and even yet it is surprising how 

 few are aware of its value to a horse. In cases of 

 inflammation of the eye, it sometimes itself becomes 

 inflamed and increased in dimensions, and the con- 

 tiguous parts likewise thickened. This either forces 

 it out of its place, or it is voluntarily produced to 

 protect the eye from the action of light. In some 

 cases it does not return into its place, and has been 

 mistaken for a tumour or extraneous excrescence, and 

 has been cut out by ignorant persons, and the eye
