YETERTNAEY OPHTHALMOLOGY. 83 



«o here we are. It may be complete or partial. Again, 

 it maybe anterior, between the cornea and the equator 

 or posterior, around the optic nerve. Anterior staphly- 

 loma has a dirty bluish color from the choroid shininfj 

 through, and is of variable size, sometimes, indeed, in- 

 volving tlie whole front of the eye. Where the tumor 

 is small, paracentesis with pressure may check further 

 progress. If verj'- extensive it may be necessary to 

 enucleate the eye. When the bulging extends all 

 around the sclera is called annular staphyloma^ and 

 when complete may protrude so far as to be called 

 hvphthalmus. 



Injuries of the Sclera. — ^Dangerous, as they com- 

 plicate adjoining tissues and as they permit contents 

 of tlie eye to escape. Small wounds may heal 

 re.adily. Clearly cut, may be united by a fine suture ; 

 2C[v^ protrudiiuj choroid or vitreous must he cut off with 

 scissors first. Patient kept quiet, and ice compresses 

 employed. If the wound is extensive and in the ciliary 

 region, enucleate and thus avoid sympathetic trouble.
