Gonioscopic evaluation of glaucoma patients after trabeculectomy

Seventy-three eyes of 65 patients with various types of glaucoma have been evaluated before and after trabeculectomy. These cases have been examined gonioscopically preoperatively and in the 1st, 3rd, and 6th months. The status of the trabeculectomy defect, and synechiae related to the area, factors predisposing to the development of synechiae, have been looked at. Peripheral anterior synechia formation was more pronounced in chronic angle closure glaucoma, exfoliative glaucoma and secondary glaucoma. The relationship between synechiae and intraocular pressure has been defined. The eyes with total peripheral anterior synechia had a lesser degree of success in lowering the intraocular pressure.
