[Comparison of results of iridencleisis and covered goniotrepanation]

Monolateral fixed iridencleisis and goniotrepanation with a scleral flap are reliable long-term pressure-regulating procedures for all forms of primary glaucoma. They involve little risk of complications. Goniotrepanation with a scleral flap is a technically simpler procedure and is preferred because of the good results obtained with it. Iridencleisis seems to offer advantages only in cases of protracted acute glaucoma.
