DISEASES OF THE EYE 95 



is nothing better than half a teaspoonful of cod- 

 liver oil emulsion night and morning. 



Opacity of the Cornea. 



As already stated, this may follow upon oph- 

 thalmia, but it is also the result of external injuries, 

 such as a scratch from a thorn, or a scratch pro- 

 duced by fighting with another cat, although the 

 membrana nictatans is fairly well developed in the 

 cat. During distemper, opacity of the cornea 

 sometimes occurs. 



Treatment. 



The cat may be temporally, or permanently, 

 blind much depending upon the cause, though 

 the degree of blindness varies. 



The reparative power of the eye is great, and 

 what looks serious often turns out fairly satisfac- 

 tory, as nature appears to exert specially recupera- 

 tive powers in this region. 



Four grains of silver nitrate added to one ounce 

 of distilled water makes a very useful eye lotion, 

 particularly suitable for some cases of opacity of 

 the cornea. 



The animal should be held by an assistant : the 

 eyelids separated, and a few drops of the lotion 

 dropped into the eye night and morning. 



Lead lotion should not be used in the treatment 

 of this diseased condition.
