Conjunctivitis: Inflammation of the Eye 



Most inflammations of the respiratory passages 

 extend to and involve the eye structures also. 

 These affections of the eye have been described 

 under catarrh, roup, etc. 



There are many causes of inflammation of the 

 mucous membrane of the eye aside from the speci- 

 fic germs heretofore mentioned. A chick was 

 brought to the laboratory with one eye very much 

 swollen. Upon examination, there was found a 

 piece of straw about one-fourth of an inch in 

 length lodged in the conjunctival sac. Upon re- 

 moval of this piece of straw, and the application 

 of a one-per-cent solution of zinc sulphate, the 

 inflammation subsided in the course of a day or 

 two. 



The number and variety of foreign bodies that 

 may gain access to the eje structures and set up 

 inflammation are numberless. In most cases their 

 careful removal and washing the eye with a sat- 

 urated solution of boracic acid or a solution of 

 zinc sulphate and water, 1 to 100, is all the treat- 

 ment that is required. 



Similar washes are indicated for conjunctivitis 

 due to injuries, spurring, picking blows, etc.
