title: Comparison of partial-thickness and full-thickness filtration procedures in open-angle glaucoma.
abstract: We compared the results of partial-thickness (trabeculectomy) vs full-thickness (trephine) filtration surgery when used as the primary surgical treatment of medically uncontrolled open-angle glaucoma. Prospectively acquired data were used from a series of patients who were examined and operated on by one surgeon. Both groups of data were gathered consecutively and concurrently. The choice of operation was made on the basis of the pressure level required for control of the glaucoma, the full-thickness procedure being chosen for eyes with the most advanced cupping and field loss. The partial-thickness group had a significantly higher postoperative pressure and signficiantly lower incidences of postoperative flat anterior chambers and identifiable filtration blebs.
