Symptomatic or Metastatic Iritis. 397 



and instruments must be rendered absolutely aseptic b\- carbolic 

 acid and boiling water, and the antisepsis of the eye must be 

 carefully maintained until the wound is healed. This tends to 

 relieve congestion in the iris and to moderate the secretion in the 

 anterior chamber, so that the former extreme tension does not 

 recur. In making choice of the seat of the iridectomy a selec- 

 tion may be made which will do away with adhesions, or one 

 that will expose a portion of the lens which is still transparent, 

 and which may restore vision when obscured by a cataract. 



In traumatic cases there should be extra care in maintaining a 

 thorough antisepsis of the eye as the great danger is that of in- 

 fective panophthalmitis. The iiijection of antiseptic liquids 

 under the eyelids, and the covering of the eye with antiseptic 

 cotton wool or with a soft rag wet with an antiseptic lotion are 

 important factors in treatment. 



SYMPTOMATIC OR METASTATIC IRITIS. 



Complications of infectious diseases, influenza, contagious pneumonia, 

 strangles, tuberculosis, omphalitis. Symptoms : exudation of fibrine and 

 blood, with those of simple iritis. Treatment: as in iritis, plus measures 

 for the specific primary disease. When second eye is threatened enuclea- 

 tion. 



Under this head MoUer describes those forms of iritis which 

 occur as complications of various infectious diseases. It has 

 long been observed that iritis and other ophthalmias, occurred as 

 complications of the acute infectious di.seases of the respiratory 

 organs of the horse formerly known under the general name of 

 " influenza." More recently many veterinarians and others have 

 classed these influenza irites separately under the name of "pink- 

 eye." The same can be said of "contagious pneumonia" 

 (bru.stsenche) of horses which is distinctly caused by the diplococ- 

 cus (^streptococcus) pne2c?ti07iia equiiia. Attention was called to 

 the iritic complication of this disease in 1881 by Siedamgrotzky 

 and it has been often noticed since. Conjunctivitis is however a 

 more frequent complication of this disease than iritis. In both 

 influenza and contagious pneumonia the iritis often supervenes
