bleeding from the angular vein of the e3'e or by leeching or 

 cupping is not open to the same objection. 



Counter-irritants are, however, more suitable. A .stout .silk 

 thread may be in.serted above the lower end of the zygomatic 

 ridge and bathed and moved daily to prevent the lodgment of 

 pus. Or a blister of cantharides or biniodide of mercury may be 

 rubbed in on an area as large as a silver dollar in the same sit- 

 uation. 



In all cases a strong .solution of atropia sulphate (2 per cent). 

 may be instilled into the eye once or twice daily. Or a mixture 

 of atropia and cocaine (i per cent, of each) will give even greater 

 relief. If to these is added i percent, of pyoktannin we get a 

 collyrium which is at once an3e.sthetic, midriatic and antiseptic. 

 This is often of material value. Vigezzi advises a mecuric chloride 

 lotion (i : 1000) as a collyrium, and for injection in the sub- 

 mucosa. 



If the local inflammation runs high an astringent lotion may 

 be applied externally on a soft rag hung over the eye and kept 

 con.stantly wet. Sugar of lead or acetate of zinc may form the 

 basis of such lotion with a little atropia or morphia added. 



Puncture of the cornea and iridectomy have been strongly 

 advocated on the ground that the disease is identical with glau- 

 coma, but the burden of evidence is decidedl}^ against their use 

 as a regular method of treatment. In case of increased intraocu- 

 lar tension, however, the puncture of the cornea can be very 

 profitably employed, but it should be reserved for such special 

 cases. Theoretically, iridectomy should be advantageous in pre- 

 venting a relapse, but experience has not fully sustained this. 

 When employed, the most careful disinfection should be .secured. 

 Under rational treatment the attack subsides in ten days and the 

 eye may appear to be restored to the normal condition in two 

 weeks. This natural tendency to a temporary recovery has 

 served to give a wide acceptance to the most irrational methods 

 of treatment, which have not in any sense hastened the recovery. 



As .soon as active inflammation and hyperthermia subside, 

 every attention should be given to prevent a relap.se, and to this 

 end all the measures mentioned under prevention and which can 

 be applied to the individual case should be adopted. Among 

 these, moderate exercise or regular work mu.st never be omitted.
