444 SPECIFIC OPTHALMIA. 



the Chlorate of Potass in 2-drachni doses, and repeat it every 

 thirty or forty hours for four or jGlve days in succession ; or it 

 may be given in alternation with China or Nux Vomica. Sul- 

 phur is also an excellent remedy ; give it in 2-drachm doses of 

 the 1st trituration ; its use should be continued for some time. 



Diet and Gteneeal Management. — The diet and general 

 management of the patient are matters which require close 

 attention on the part of those having the care of horses affected 

 with this disease. Derangement of the stomach will aggravate 

 the disease, and the least undue exposure of the animal to cold 

 and wet is almost certain to be followed by an acute attack of 

 the disease. The vital energies of the patient should therefore 

 be sustained to the utmost, and every precaution taken to guard 

 the animal against unnecessary exposure. 



OPACITY OF THE CORNEA. 



Opacity of the Cornea is very frequently the effect of an 

 attack of Opthalmia arising either from the common or the 

 specific forms of the disease. Sometimes the opaque condition 

 of the Cornea is speedily removed by absorption without any 

 treatment whatever; at other times it remains, when active 

 treatment, with a view to its removal, becomes necessary. It is 

 desirable to remove it because the opacity frequently causes 

 horses so affected to shy a great deal, and they are rendered 

 dangerous in consequence. 



One of the best remedies for this purpose is the Tincture 

 of Iodine, which should be applied directly to the surface of the 

 eye by means of a fine camel's hair pencil. The application 

 should be repeated two or three times a week, for two or three 

 weeks in succession if necessary ; giving to the animal at the 

 same time 4-drachm doses of Iodine of the 1st dilution, mixed 

 with 4 or 5 ounces of water, for a like period.
