Background: Trabeculectomy is the "gold standard" initial surgical procedure for open-angle glaucoma worldwide. During the last decade, the introduction of less invasive procedures, including new bleb-forming surgery such as the MicroShunt, has altered the approach of glaucoma management. At present, there is insufficient evidence comparing the effectiveness between these procedures nor versus trabeculectomy.

Purpose: To assess if ocular motility impairment, and the ensuing diplopia, after Baerveldt Glaucoma device (BGI) implantation, is related to the presence of a large fluid reservoir (bleb), using Magnetic Resonance Imaging (MRI).

Methods: In a masked observational study (CCMO-registry number: NL65633.058.

Purpose: To determine whether the postoperative corneal endothelial cell density (ECD) differs between glaucoma patients who underwent Baerveldt implant (BGI) surgery and patients who underwent a trabeculectomy (TE) over 5 years ago.

Methods: Cross-sectional, observational study including 34 patients who underwent TE and 36 patients who underwent BGI surgery 5-11 years ago, as part of a randomized clinical trial. None of the patients had a history of intraocular surgery prior to their glaucoma surgery.

Purpose: To investigate the effect of two surgical techniques in primary Baerveldt glaucoma implant (BGI) surgery, that is the sutured technique and the unsutured (free) plate technique, on the ocular motility and prevalence of diplopia. We hypothesize that the free plate technique results in a lower diplopia prevalence.

Methods: We performed a prospective study of patients who underwent BGI surgery with the free plate technique and compared them with patients from a previous study who had undergone BGI surgery with the sutured technique.

Purpose: Although the Baerveldt glaucoma implant (BGI) initially was reserved for refractory glaucoma, its role in the surgical management of glaucoma has shifted towards a primary treatment choice. We performed a randomized prospective study to compare BGI surgery and trabeculectomy (TE) in patients without previous ocular surgery.

Methods: We included 119 glaucoma patients without previous ocular surgery.

Purpose: The purpose of this study was to quantify any diplopia and motility changes after the implantation of a Baerveldt glaucoma implant (BGI) or after trabeculectomy (TE).

Methods: We analyzed 51 patients with a BGI and 52 patients with a TE from a prospective cohort study. To quantify any diplopia, we asked patients about the presence of diplopia at 1 year after surgery.

Purpose: To compare a Baerveldt implant and trabeculectomy with respect to intraocular pressure (IOP) and failure rate at 1 year of follow-up. Secondary outcomes are pharmacological therapy and complications at 1 year of follow-up.

Methods: This was a randomized, comparative study.

Purpose: During the last decades, the Baerveldt Glaucoma Implant (BGI) has proven effective in the surgical treatment of glaucoma. Various surgical procedures have been used for its implantation and these may yield different clinical outcomes and different intraoperative and postoperative complications. We evaluated the success rate of BGI and compared complications between 2 different surgical implantation techniques.

Purpose: The aim of this study was to investigate the usefulness of a long-acting miotic (physostigmine) after phacoemulsification in preventing peripheral anterior synechiae (PAS), lens dislocation, and high postoperative intraocular pressure.

Methods: This was a prospective randomized controlled trial of 400 patients (400 eyes) scheduled for phacoemulsification. Patients were randomly assigned either to receive a single application of physostigmine ointment directly after phacoemulsification or not.

Purpose: To compare the efficacy of dexamethasone 0.1% eyedrops after phacoemulsification versus a single perioperative subconjunctival injection of betamethasone acetate 5.7 mg/mL to prevent anterior segment inflammation and macular edema.

Purpose: To describe an effective surgical technique to visualize an obscured leading edge of a capsulorhexis.

Design: Prospective, interventional case series.

Methods: In six eyes of six patients in which the capsulorhexis was started but could no longer be seen during surgery, the anterior chamber was irrigated to remove all viscoelastic, and 0.
