[Surgical indications in glaucoma].
A number of aspects of glaucoma surgery are discussed. Complete drainage of the aqueous via the subconjunctival space results in underperfusion of the trabecular meshwork, leading to significant impairment of the trabecular function. In certain cases, therefore, we prefer trabeculotomy, even though its pressure-lowering effect is inferior to that of fistulizing surgery: trabeculotomy preserves the unaffected trabecular meshwork. Laser trabeculoplasty has the advantage of increasing the outflow facility. In angle-closure glaucoma, iridectomy is performed as an initial procedure in every case in order to eliminate pupillary block. The transcorneal approach ensures watertight wound closure and preserves the conjunctiva for fistulizing surgery if necessary. Glaucoma surgery can usually be performed in lid akinesia and subconjunctival infiltration. This alternative helps to avoid retrobulbar injection when the optic nerve is already severely damaged by glaucoma.
