openangle glaucoma. Thirty-eight patients with primary open-angle glaucoma, in whom one eye had glaucoma surgery and the other
eye received topical antiglaucoma, therapy, underwent bilateral POBF testing before treatment and at 3-month follow-up The
POBF in trabeculectomy-treated eyes was significantly higher at 3 months than in contralateral eyes treated medically.
