This failing, Gaillard's sutures may succeed. With a pair of 

 forceps with looped, transversely elongated blades, pinch up skin 

 and nmscle sufficient to correct the entro]")ion, and passing a 

 needle twice through this fold with an interval of 3 mm., tie 

 the suture over a small roll of cotton. The stitches ma}- be re- 

 moved in two days and the cicatrices may permanentl}' obviate 

 the deformity. 



The older plastic operation is more trustworthy : The skin of 

 the affected lid is pinched up to such an extent in length and 

 breadth, as to correct the entropion and is then excised with 

 sharp scissors or bistuory so as to leave a long elliptical sore. 

 The edges of this are then carefully sutured together and the re- 

 sulting union corrects deformity. In case the entropion is caused 

 by an old standing cicatrix, it may be necessary, first, to make 

 a careful incision along the edge of the lid so as to separate the 

 tarsus and conjunctiva from the cilia and Meibomian ducts, and 

 then to proceed with the plastic operation on the skin. 



TURNING OUT OF THE EYELID. ECTROPION. 



In large dogs, in old age, debility, conjunctival swelling, cicatrized skin 

 of lids, distortions of lids. Symptoms : exposure of pelpebral mucosa, 

 weeping eyes, conjunctival hypertrophy (chemosis). Treatment: scarify 

 or excise a fold of mucosa, astringent antiseptics, Snellen's suture, Diefen- 

 bach's operation, Wharton Jones operation. 



This is much more pommon than entropion, but much less in- 

 jurious as the tarsi and lashes do not irritate the conjunctiva. It 

 is especially common in large dogs (hounds, mastiff) and usually 

 affects the inner part of the lower lid. Old age and debility con- 

 tribute materially to the condition, the lack of tone or paresis 

 being an important factor. It may, however, occur in any ani- 

 mal, from conjunctivitis and swelling of the mucosa, from cica- 

 trices or old standing disease of the skin of the eyelids, or from 

 imperfectly healed wounds leaving distortions of the lower lid. 

 It is most frequent in the lower lid, and the slightest pendulous 

 condition, which detaches the tarsus from the bulb, and exposes 

 a narrow zone of the conjunctiva is considered to be an ectropion.
