PALSY OF THE NEEVE OF SIGHT AMAUROSIS. 



This is a partial or complete blindness as a result of paralysis 

 of the optic nerve (nerve of the eye) without there being much 

 change in the looks of the eye. The eye may look clear and all 

 right and the horse be perfectly blind. 



Causes. It may be caused by tumors or other diseases of the 

 brain; blows on the head that injure the optic nerve. Severe 

 bleeding may cause this trouble, and it is sometimes seen in 

 mares -heavy with foal. 



Symptoms. The eyes are clear and sound looking, with the 

 exception that the pupil is generally dilated and round, and the 

 horse can see only partially or not at all. Both eyes are gen- 

 erally affected, except where it is due to an injury of one eye. 



Treatment. The treatment of this disease is not generally suc- 

 cessful. Unless taken when first affected, treatment is useless. 

 Give one dram of powdered mix vomica once a day in damp feed 

 and apply a blister behind the ear.
