The Effect of Scleral Buckle Surgery on Tonographic Outflow Facility, Positional Intraocular Pressure, and Ocular Biomechanics.
Ophthalmol Glaucoma
February 2024
Department of Ophthalmology, Mayo Clinic, Rochester, Minnesota. Electronic address:
Purpose: To investigate the in vivo effect of scleral buckle surgery on ocular biomechanics and aqueous humor dynamics.
Design: Prospective observational cross-sectional study.
Participants: Nine patients with unilateral 360 degree encircling scleral buckles without vitrectomy for rhegmatogenous retinal detachments, between 3 and 39 months postoperative.
Reduction of Intraocular Pressure and Aqueous Outflow Resistance After Modified 360-degree Suture Trabeculotomy.
J Glaucoma
March 2023
Department of Ophthalmology, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Sapporo.
Prcis: Decreasing aqueous outflow resistance at trabecular meshwork is the main mechanism of modified 360-degree suture trabeculotomy (ST), and the preoperative C-value, which shows aqueous outflow resistance, is likely to be useful for predicting intraocular pressure (IOP) reduction.
Purpose: To clarify the mechanism of IOP reduction and the preoperative prognostic predictor of modified 360-degree ST.
Materials And Methods: Forty-three eyes of 32 patients with glaucoma who underwent ST at Hokkaido University Hospital between April 2017 and February 2020 were enrolled.
Goniotomy for Steroid-Induced Glaucoma: Clinical and Tonographic Evidence to Support Therapeutic Goniotomy.
J Pediatr Ophthalmol Strabismus
January 2016
Purpose: To report the surgical results of goniotomy for corticosteroid-induced glaucoma and to provide evidence to support its use as initial surgical therapy.
Methods: The medical records of 5 patients with a history of goniosurgery for steroid-induced glaucoma were reviewed. Preoperative and postoperative clinical findings were reviewed, including the topical use of steroids, tonometric and gonioscopic findings, goniosurgery, and postoperative results.
Effect of primary selective laser trabeculoplasty on tonographic outflow facility: a randomised clinical trial.
Br J Ophthalmol
November 2010
Department of Ophthalmology, St Thomas' Hospital, London, UK.
Purpose: To investigate the effect of 180° versus 360° primary selective laser trabeculoplasty (SLT) on tonographic outflow facility and intraocular pressure (IOP).
Design: Prospective, single masked randomised clinical trial.
Participants: Patients with untreated primary open angle glaucoma or ocular hypertension both with IOP > 21-35 mmHg.
Purpose: To evaluate and compare the intraocular pressure measurement variability between Goldmann applanation tonometry (GAT), Pascal dynamic contour tonometry (DCT), and ocular response analyzer (ORA) tonometry.
Methods: Subjects were prospectively recruited from consecutive Albuquerque VA Medical Center eye clinic patients that were previously diagnosed with ocular hypertension, glaucoma suspect, primary open-angle, or normal pressure glaucoma. Two sets of intraocular pressure measurements (3-4 ORA, 2 DCT, and 2 GAT) were obtained approximately 15 minutes apart.
