The American encyclopedia and dictionary of ophthalmology Edited by Casey AWood, assisted by a large staff of collaborators . Abscission. Method of Lagrange. Showing the purse-string sutures holding themuscles protruding from the opening. ABSCISSION OF THE EYE 39 the cut edges sutured and the remaining globar tissues form a padfor an artificial eye. The operation was first proposed by Saint Ivesin the 18th century, but since that time many operators have favoredvarious forms of abscission (of the cornea), combined or not withevisceration of the globar contents. Two well-known operative pro-cedures are by Critchett and Lagrange. Critchett passed three curved needles, armed with sutures, throughthe sclera above and below the cornea, a little back of the area tobe removed. The needles were left in position until an elliptical seg-ment of the eyeball was cut out with knife and scissors. The seg-ment included the cornea, iris, lens and some sclera. The needles hin-dered the escape of vitreous. After the amputation had occurred,. Abscission. Method of Lagrange. The relative positions of the sutures. the needles were drawn through and the wound was closed by tyingthe sutures. Lagrange modified the operation by making, first, the regularsclero-corneal incision and exposing the recti muscles, each one ofwhich was secured with a suture before being severed. A purse-string suture was then passed around the conjunctival of the anterior portion of the globe followed, after whichthe superior and inferior recti muscles were tied together and thenthe internal and external recti muscles. The purse-string suturewas then tied and the operation completed.— (F. A.) Abscission of the eye. See Enucleation of the eyeball and substitutesfor that operation. Abseifen. (G.)
