DISEASES OF THE EVE. 537 



Treatment. — Fomentations should be kept up as in simple 

 ophthalmia. The animal should receive two drachms of epsom 

 salts internally. Zinc sulphate, twenty grains; tincture of bella- 

 donna, one ounce; laudanum, one ounce; water, four ounces, may 

 be used as a wash to the eye. 



Traumatic ophthalmia is produced by wounds, foreign sub- 

 stances in the eye, etc. 



Treatmext. — Remove the foreign body. Treatment is simi- 

 lar to simple ophthalmia. 



ULCERATION OF THE CORNEA. 



This is met with more frequently in the dog than in other 

 animals. The ulcer may be touched with the nitrate of silver. 



AMAUROSIS. 



By this is meant a partial or complete paralysis of the optic 

 nerve. If there is complete paralysis, total blindness ensues. 

 The disease is characterized by a dilated state of the pupil. The 

 coats and humors of the eyes are transparent. It is a disease 

 very deceptive to the inexperienced observer. 



The disease is. caused principally by concussion, from blows 

 upon the head, disease of bone, epileptic fits, or tumors. 



The treatment of amaurosis is so unsatisfactory that it is a 

 waste of time to attempt it. 



SYMPATHETIC OPHTHALMIA. 



This condition arises from other disease in some other jiart of 

 the body <ti' fi'oni derangement of the stomach, mange, etc. 



Treatmext. — Give a drachm of jalap, and a]ij)ly zinc sulphate, 

 grains five; opium tincture, drachm one; beUadonna tincture, 

 drachm one; water, ounce one. Apply to the eye. 



Congenital blindness occurs sometimes throughout the whole 

 litter of puppies, due to heredity. The puppies should be de- 

 stroyed.
