THE SUPERIOR OBLIQUE MUSCLE AND 

 ITS PULLEY 



AFTEE the lacrimal gland has been dissected 

 away, a beginning will have been made for cut- 

 ting away the fat and the connective tissue. 

 The first thing to do then is to locate the su- 

 perior oblique muscle. Try to keep track of 

 which part of the eye is the inner side. Hav- 

 ing located the inner side, feel along the top 

 for a little hard eminence. That is the pulley. 

 Begin to dissect around the pulley, not through 

 it, and then follow the muscle along to its 

 origin; do not separate the muscle from its 

 origin. When the superior oblique is com- 

 pletely freed, the action of the muscle may be 

 readily demonstrated by holding the "ring" 

 or tendinous pulley with the fingers of one 

 hand, while the muscle is pulled backward and 

 forward with the other.
