TECHNIQUE OF EYE DISSECTIONS 



too fresh the ciliary processes will not be 

 easily detached from the hyaloid (zonular pro- 

 cesses), and if the eye has been in a preserv- 

 ing fluid, the same result will follow. A 

 sheep's eye will make a, better specimen even if 

 it is small, because the ciliary processes are 

 more easily separated from the zonular pro- 

 cesses. If a bullock's eye is used, it must be 

 left in a cool place a, day or two longer than 

 in the case of a sheep's eye, in order to permit 

 a long enough time to elapse to allow disin- 

 tegration of the eye to take place sufficient to 

 have the two processes separate easily and 

 cleanly. 



With a pair of dissecting forceps pinch up 

 the sclerotic about 5 mm. anterior to the equa- 

 tor. With a pair of small, fine-pointed scis- 

 sors, make an incision. (Fig. 2.) Next hold the 

 eye in the left hand without exerting any pres- 

 sure. Insert the point of the scissors into the 

 incision which has been made, and cut. Be 

 careful to keep the point of the scissors close 

 to the sclerotic or an untimely puncturing of 

 the choroid will occur. (Fig. 3.) Continue the
