FRACTURE OF THE ORBIT 175 



When atrophy of the optic nerve takes place from 

 pressure, very Httle can be done. If celluHtis and ab- 

 scess are not controlled by the above measures, it will 

 be necessary not only to enucleate the eyeball, but, 

 in many cases, to cut away all the tissues in the orbit 

 (exenteration), as the pus may burrow through the 

 sclera, causing a panophthalmitis, or it may endanger 

 life by extending to the meninges of the brain.
