Surgical revision in a case of iris incarceration after trabeculectomy in congenital glaucoma

Background: Incarceration of the iris is a potential complication following trabeculectomy in primary congenital glaucoma. Although this complication is mentioned in the literature, nothing is reported about the technique of surgical revision. Patient: In a patient with primary congenital glaucoma we had to perform su rgical revision of the anterior chamber, because progressive pupil peaking had developed after trabeculectomy and the optical axis had been obstructed . Simple resolving of uveal tissue from the incarceration site was not poss ible; the iris incarceration had to be cut under gonioscopic control. Conclusion: Surgical revision of an incarceration of the iris can be safely performed by means of gonioscopy. The outcome of intraocular pressure is n ot necessarily influenced.
