DISEASES OF THE EYES. 305 



Ophthalmia which is due to cold or some constitutional cause, as 

 is sometimes the case, requires treating according to general symp- 

 toms, as follows: 



Aconite 3X when the pulse is quick, the skin dry and the tem- 

 perature at all higher than normal. 



Belladonna 3X. — Evident pain, swelling and redness of the 

 white parts; dryness of the membrane of the eyeball; intolerance 

 of light. 



Euphrasia ix is par excellence the remedy when there is a pro- 

 fuse secretion of tears; great sensitiveness to light; a tendency to 

 rub the eye, as though it itched or stung, and especially when the 

 lachrymal secretion flows down the nostrils. 



Argentiim nitricuin 3X for old-standing and chronic cases, when 

 the lachrj-mal secretion is no longer thin, but has asumed a thick 

 and purulent condition. 



Mercurius corrosivus 3X. — In acute forms of the disease, when 

 the animal has an evident dread of light, and when the glands 

 between the jaws and around the throat are swollen. 



Arsenicnin album 3X for w'eak, emaciated animals, and when 

 the inflammation is obstinate and intractable; the lachrj-mal secre- 

 tion is acrid and as it were burns the skin over which it flows; light 

 aggravates the condition and produces an increased flow of the 

 secretion; the horse shakes his head every now and again as 

 though it experienced paroxysms of stabbing pain in the eyeballs. 



Accessory Measures. — The eyes should always and regularly 

 be fomented with warm water, any agglutinated secretion should 

 be carefully washed away, and when Aconite, Belladonna and 

 Euphrasia are indicated, a compress saturated with a lotion of the 

 remedy — about one in twelve — should be applied to the eyes as 

 before directed. In those cases where Argentiim nitricum is indi- 

 cated a solution made by dissolving two grains of Nitrate of Silver 

 in an ounce of distilled water should be introduced over the eye- 

 balls and under the eyelids, with a camel' s-hair brush, night and 

 morning. 



Parasites. — A worm is occasionally observed floating about in 

 the humor of the eye, especially among horses in India and 

 Canada; the symptoms are those of inflammation, there is an in- 

 tolerance of light and the eyelids are kept closed; it is prevalent 

 among horses that are allowed to run loose in low, humid situa-
