SURGERY -OF THE EYE 199 



the head, he then seizes the growth at its corneal 

 attachment and with the Graefe's scalpel proceeds 

 to dissect it off. The blade of the knife must be 

 kept parallel with the cornea to prevent injury, and 

 moderate tension should be kept on the forceps 

 until the growth is finally removed. Hemorrhage 

 is easily controlled by adrenalin solution and mod- 

 erate pressure. 



The after-treatment consists in daily cleaning the 

 eye with boric-acid solution, until all irritation has 

 subsided. 



Displaced Orbital Gland 



In the dog, just beneath the membrana nictitans, 

 is situated a little rounded mass of glandular tissue, 

 the orbital gland. This gland, as the result of 

 traumatism, may become displaced and appear at 

 the inner canthus of the eye as a reddish and often 

 angry-looking mass which is exceedingly unsightly 

 and sometimes produces irritation. While easily 

 replaced, it is next to impossible to retain it in posi- 

 tion, and surgical interference is the only means of 

 removing this eyesore. 



The instruments to be used are blunt-pointed 

 scissors, rat-toothed forceps, and dressing forceps. 

 Have ready also swabs, an adrenalin solution, and 

 a four-per-cent cocain solution. 



Place the patient in the abdominal position and 

 apply a local anesthetic of four-per-cent cocain. 



Technic. — After confining the patient in the ab- 

 dominal position, a few drops of the cocain solution 

 are placed in the lower conjunctival sac, which later 

 on is flooded with adrenalin solution. When anes- 

 thesia is complete the assistant, who also steadies 

 the patient's head, holds the membrana nictitans 

 aside with the dressing forceps while the operator 

 seizes the gland with the rat-toothed forceps and,
