[Surgery of glaucoma: intrascleral trabeculo-irido encleisis]

The objective of this work is to appraise a surgical proposal for the treatment of glaucoma which attempts to avoid the relapses and complications. The technique consists of the fulfillment of a filtering blister (chamber of pressure derivation) using a support of corneoscleral trabeculae together with a support of iris placed into the sclera through a scleral flapping. 70 patients (125 eyes) with more than 7 years after surgery with this technique were selected at random. Their field of vision and eye pressure were evaluated and biomicroscopy and gonioscopy were practiced. The efficiency was of 95%, and patients with a field of vision between 10 and 20 degrees, and with pressures higher than 40 mmHg before surgery showed an improvement of an average of 5 degrees. The results are based on the successful endothelization of the accessory chamber achieved and in the building of a bond that stops the closing of the channel between the anterior and accessory chambers. The results of this long term follow-up suggest that the technique analyzed offers a good alternative to the surgery of glaucoma.
