Medical therapy versus trabeculectomy in patients with open-angle glaucoma

ABSTRACT Purpose: To compare therapeutic outcomes between trabeculectomy and medical therapy in patients with open-angle glaucoma. Methods: In the present retrospective comparative study, the medical charts of 284 patients (eyes) newly diagnosed with open-angle glaucoma who had received conventional medications (n=188) or undergone fornix-based trabeculectomy (n=96) at a teaching eye hospital were reviewed.
