scar tissue resulting from ulceration is also unable to with- 

 stand the intra ocular pressure and the cornea bulges for- 

 ward, forming a partial staphyloma. A staphyloma from 

 either of the foregoing causes is generally opaque, gray or 

 white colored. In the healing of perforating wounds, the 

 iris may adhere to the scar tissue, should the corneal scar 

 then become distended it would carry with it the iris and 

 the result would be called an Iris-staphyloma. 



Occasionally intra ocular pressure pushes forward the en- 

 tire transparent cornea.

The treatment of staphyloma is mainly preventative. In 

 impending perforations of the cornea from ulceration, wounds 

 or abscesses, a compress bandage and a 1 per cent, solution 

 of eserine may be employed. In cases of established per- 

 foration the eserine or atropine may be used as before di- 

 rected for perforating wounds of the cornea. Proper treat- 

 ment of abscesses, ulcerations and wounds of the cornea 

 will also prevent the formation of a staphyloma.
