PALSY OF THE KEEVE OF SIGHT. AMAUROSIS. GLASS EYES. 



Causes. Congestion, tumors, dropsy, or other disease 

 of the brain. Injury to the nerve of sight by pressure or 

 otherwise. Inflammation with exudation into the retina. 

 Excess of light. It may be symptomatic from overloaded 

 stomach, from bloodlessness, and sometimes from gesta- 

 tion. 



Symptoms. Eyes unnaturally clear from wide dilatation 

 of the pupils. Failure of the pupils to contract when ex- 

 posed to Mght or sunshine, or to dilate in darkness. The 

 subjects do not wince when a feint is made to strike them 

 unless the hand produces a current of air. The animals 

 step high to avoid obstacles and have very active ears, 

 which are constantly exercised to make up for lack of 

 sight. 



Treatment. If due to removable cause stop this, then 

 blister the cheek or behind the ear, as for ophthalmia, and 

 give nerve stimulants (strychnia, nitrate of silver, etc.) 



Among the other affections of the eye are Glaucoma, the 

 true nature of which can only be ascertained with the 

 ophthalmoscope ; Cancer which demands the skill of the 

 anatomist for removal ; Staphyloma or vascular tumor of 

 the cornea ; Wm'm in the eye (Filaria OcuM) which is to be 

 extracted by skillful puncture; etc.
