I02 CANINE AND FELINE SURGERY 



necessary to keep it at some distance from the orbit, the 

 framework of an ordinary ^^•ire or leather muzzle can be 

 utilized to give the requisite support. 



Examination for, and removal of, Foreigrn Bodies. 



The removal of foreign bodies from the e^e can be 

 accomplished quite painlessly under the influence of cocaine, 

 eucaine, or a mixture of the two. A small quantity of a 

 2 to 4 per cent, solution, applied with a camel-hair brush, 

 will produce a very effectual anaesthesia in from one to three 

 minutes. The ej-elids are then separated with the fingers or 

 by the aid of a speculum, the foreign body being sought for, 

 and, when found, removed either with forceps, a blunt probe, 

 or some sharp instrument, the choice of which must be 

 determined by the operator. In using anything sharp, great 

 care must be taken that the instrument is held in such a way 

 that the cornea will not be injured if the patient unexpectedly 

 moves. A few drops of castor-oil are of great assistance as 

 a lubricant, and, in order to give the eye absolute rest 

 afterwards, it is a wise plan to put the patient in a 

 darkened room or enforce the wearing of an eye-shade for 

 a few days. 



Pterygium or Dermoid Growths on the Cornea. 



Symptoms. — If the hairs turn in there is a watery discharge 

 from the eye ; irritation and perhaps a nebula on the cornea. 

 The growth is usually congenital and easily seen. 



Operation. — Anaesthetize in the usual waj- with cocaine 

 or eucaine, and carefully dissect off the growth with a small 

 and very sharp scalpel or razor and forceps. It is rarely of 

 permanent value to merely pluck out the hairs, as they 

 almost invariably reappear and cause more irritation than 

 before.
