Staphyloma is a name given to any bulging cornea or sclera 
of the eye, or the formation of tumors involving them ; the most 
common forms are : 
1. Anterior ( kei'atoglobus ). 
2. Posterior, a bulging of the sclera posteriorly. 
3. Annular, which surrounds the ball either equatorially or 
partially. 
4. Intercalated, found between the sclera and the iris. 
Of these only one will be considered as an indication for 
paracentesis ; the other forms are generally due to neoforma¬ 
tions, or other pathological lesions which are not treated in this 
manner. The first, the keratoglobus or anterior staphyloma 
(Fig. 47), when caused by intraocular pressure or dropsy of the 
anterior chamber, is often benefited by removing the pressure. 
Staphylomata of the cornea may appear in various forms ; it 
may b pdrtial or complete , racemose, conical or globose. They
