The American encyclopedia and dictionary of ophthalmology Edited by Casey AWood, assisted by a large staff of collaborators . d catgut suture should now be passed by means of aneedle-holder through the conjunctiva, capsule of Tenon and tendonfrom without inwards and then back again from within quilts the entire mass together by means of a firm, solid stitchthat will not pull out; after which the two ends of the suture arecarefully laid aside so as not to interfere wdth the next step in the 246 ALLPORTS OPERATION FOR PTOSIS operation. The external rectus is then picked up, liberated, en-gaged in the Princes forceps together with the conjunctiva andcapsule of Tenon, cut away from the sclera, quilt-stitched with thesame needle and suture, etc. The same steps are taken (in theirorder) with the inferior and the internal rectus, after which theneedle may be withdrawn from the suture. The purse-string sutureand its two free ends should be laid carefully aside to facilitatethe subsequent steps of the operation which are exactly the sameas in the Ferrall or Bonnet operation just described. The operation. Enucleation of the Eyeball. (Allport.) is completed by pulling the continuous suture containing the rectimuscles, the capsule of Tenon and the conjunctiva together andtying the mass in a firm, hard knot. Great care should be exer-cised when the scissors are introduced to sever the optic nerve,that the suture is not cut in the process, an accident which is notat all impossible. If, however, this misfortune should occur themuscles should be painstakingly picked up and the continuous,purse-suture re-introduced as before. See, also, Enucleation of theeyeball.—(F. A.)Allports operation for ptosis. The chief features of this operationare a thorough denudation of the tongue flap so that it may grow tothe raw surface of the bridge, and removal of the corners of thelateral flaps on the lid surface, to make them fit more accuratelyand thus avoid puckering of the lid.
