ENEUCLEATION. 



Eneucleation. — Instruments necessary will be 

 curved blunt-pointed scissors, speculum, fixation for- 

 ceps and a strabismus hook. The administration of 

 cUoral hydrate in full doses, and also cocaine 

 4 per cent., is necessary to this ox^eration. 

 Separate at the corneal margin the conjunctiva 

 from the globe, going completely around, of course. 

 Then divide the attachment of the superior straight, 

 after catching it on the strabismus hook. Have an 

 assistant hold the wound open with this hook, while 

 you take another and insert it under the insertion of 

 the internal straight, and so proceed with the balance 

 of the muscles. Some divide the obliques previous to 

 the optic nerve, and others, the reverse — protruding 

 the eye by pressure — dividing the obliques and then 

 the nerve. Do whichever method comes the more 

 natural to you, and as the exigencies of the case pre- 

 sent. With the scissors closed, push, probe and sepa- 

 rate your way back, until the nerve is reached on the 

 inner side, and, with one cut, divide the nerve. Will 

 have an immediate flow of blood, which is easily con- 

 trolled by pressure. This operation is followed, as.
