TECHNIQUE OF EYE DISSECTIONS 



in examining the inside of the eye. Care must 

 be taken not to lacerate the anterior surface 

 of the lens when the iris is drawn back by 

 the pins. 



Putting the pins into the cornea, and using 

 them as levers with the point of entrance in 

 the cornea as a fulcrum, will pucker the cornea 

 considerably, and a good clear fundus cannot 

 be obtained. This is easily overcome. Simply 

 gather up all the tissues surrounding the eye, 

 force them backward, and hold them firmly 

 with the fingers of the left hand. (Fig. 56.) 

 The right hand is then free to handle the skia- 

 scope or ophthalmoscope, so that the interior 

 of the eye may be thoroughly examined. 



Another way to prepare an eye for ophthal- 

 moscopic examination is as follows: Go to a 

 slaughter house and procure a beef eye from 

 an animal that has been killed but a few min- 

 utes previously. Placing the eye immediately 

 into an 8 per cent, solution of cocaine and 

 leaving it there for about an hour will dilate 

 the pupil to such an extent that work with the 

 ophthalmoscope will be made very easy. This,
