ENUCLEATION PRE OP
1) The animal should be restrained in a squeeze crush with its head secured to one side with a halter.
2) The animal should be sedated with Xylazine at 0.05 - 1.0 mg\kg. Sedation should not be so high so that the animal would go down.
3) The hair is clipped around the animal's eye and the surgical site is scrubbed for surgery (proper aseptic technique may be impossible because this procedure is performed on eyes with large, necrotic neoplasms or severe trauma).
4) Local anaesthesia should be administered via a 4 point retrobulbar block (A 6mm needle is inserted transconjunctivally adjacent to the globe at the 12, 3, 6 and 9 o clock positions. 5- 10 mls of lidocaine is injected at each site). A successful block is indicated by exopthalmos, corneal anaesthesia and mydriasis. The eyelids are sutured closed with the ends of the suture left long to minimize contamination of the surgical field.
