IRIDECTOMYDIALYSIS In eyes where an iridectomy has failed to relieve tension in glaucoma a portion of the root of the iris has been found to have been left behind, either adherent to the back of the cornea or held in contact with it by an entanglement of the cut end between the posterior lips of the sclero-corneal incision (Fig. 171).. Fig. 170.—Section of an eye in which a cystoid cicatrix formed after an iridec- tomy operation for chronic glaucoma. Eight months later severe iritis set in, and the eye was ultimately removed for the relief of pain. C points to the fistula formed in the sclero-corneal tissue at the seat of the operation; it is partly lined by the ciliary processes and partly by atrophied iris; S points to the edematous con- junctiva due to escape of aqueous into it. Iridectomydialysis.—-In an iridectomydialysis an attempt is made to tear a piece of the iris away from its junction with the cihary body, in the course of its removal. If the root of the iris has not previously become too intimately adherent to the back of the cornea, this is easily effected because the thinnest part of the iris is at its extreme periphery (Fig. 169). Should, however, firm adhesion have become established between the root of the iris and the cornea previous to the operation, as is often the case in long standing glaucoma, then the iris, instead of tearing away at its point of junction with the ciliary body tears through where.
