Purpose: To investigate the effect of trabeculectomy on the intraocular pressure (IOP) fluctuations caused by the postural change in patients with open-angle glaucoma. Methods: Prospective, nonrandomized study. Ten eyes of 10 patients with primary open-angle glaucoma and 3 eyes of 3 patients with normal-tension glaucoma who underwent trabeculectomy were studied. The IOP at the baseline and 3 months after trabeculectomy was measured in both sitting and supine positions. A pneumatonometer was used to measure the IOP in both sitting and supine position. Results: The mean IOP in the sitting position was 19.6±5.1 mm Hg at the baseline and 9.4±2.9 mm Hg after trabeculectomy (P
