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 m
onths. The status of the trabeculectomy defect, and synechiae related
to the area, factors predisposing to the development of synechiae, hav
e been looked at. Peripheral anterior synechia formation was more pron
ounced in chronic angle closure glaucoma, exfoliative glaucoma and sec
ondary glaucoma. The relationship between synechiae and intraocular pr
essure has been defined. The eyes with total peripheral anterior synec
hia had a lesser degree of success in lowering the intraocular pressur
e.
