Ii6 OPHTHALMOLOGY FOR VETERINARIANS 



ercise the utmost caution, judgment, and care in our 

 treatment of the primary cause. 



Just how sympathetic inflammation is brought about 

 no one seems to know definitely, but it is presumed to be 

 effected through the l3anphatic vessels or the circulatory

 instrument, the result is the same as a rule. No longer 

 than six days should elapse before removing the offend-

The iridociliary region is involved in all cases of recur- 

 rent ophthalmia of animals, and it is not uncommon to 

 see the fellow eye follow in its wake; but, until we know 

 more definitely what the exact cause is of recurrent 

 ophthalmia, we are at sea as to the best method to 

 pursue in preventing sympathetic involvement, as the 

 cause in the second eye may be the same as in the first, 

 and not sympathetic, as we understand sympathetic 

 ophthalmia. 



Treatment of Iritis and Cyclitis. — The treatment is
