Entropium operation on the superior and inferior eyelids of the dog. 



cumbency preferably upon the operating table. Shave and 

 disinfect the skin of the inverted eyelid. Grasp the skin of 

 the eyelid midway between the inner and outer canthus 

 with the forceps and elevate a skin fold parallel with the 

 border of the eyelid to such a height that the inverted 

 member assumes its normal position. Pass a finger into the 

 conjunctival sac to make sure that the conjunctiva is not 

 drawn into the skin fold. Clip the fold off with the scissors 

 immediately below the forceps, removing an oblong piece. 

 Between the border of the eyelid and that of the wound the 

 skin should be left intact for at least .5 cm. Ligate or 

 compress any bleeding vessels and close the wound by means 

 of interrupted sutures. It is usually unnecessary and inad- 

 visable to cover the parts with hood or other appliance since 

 so long as the wound is healing properly the animal will not 

 disturb it.
