Treatment. — To obtain the best results treatment 

 should be commenced early in the disease. If the fol-

 there is a tendency to recur, it may be rubbed lightly 

 every second day with a crayon of sulphate of copper. 

 If the secretion persists, argyrol in 25 per cent, solution 

 may be used, appHed every three or four hours, or silver 

 nitrate in 2 per cent, solution, used as in purulent 

 conjunctivitis. 



Cleanliness and freedom from secretion are the 

 indications, together with stimulation to enhance 

 resolution. Boric acid, aristol, calomel, etc., are used 

 as dusting-powders and also in the form of ointments. 

 The x-ray has been employed with benefit. 



Follicular conjunctivitis resembles an ordinary catar-
