Sonographic bleb visualisation after PAUL glaucoma implant surgery.

Background/aims: Bleb characteristics in the area around the plate following glaucoma drainage device (GDD) surgery are difficult to evaluate on slit lamp examination. Ultrasound sonography could be used for more detailed visualisation. The aim of this study was to describe bleb configuration after PAUL glaucoma implant (PGI) surgery and evaluate the possible correlation with intraocular pressure (IOP) in order to derive new markers for evaluating GDD function.

Outcomes of Second Trabeculectomy Versus Glaucoma Drainage Device in Juvenile Open-angle Glaucoma After Primary Trabeculectomy Failure.

Precis: Second trabeculectomy and glaucoma drainage device implantation offer similar success rates for juvenile open angle glaucoma after initial trabeculectomy failure. However, second trabeculectomies required fewer medications. A quarter of patients in both groups required a third operation after 2.

Removal of aqueous humor and conjunctival compression sutures for a dysesthesic filtering bleb: A surgical technique and case report.

Methods: Case report and surgical technique.

A New "Tube-in-tube" Method to Extend Glaucoma Drainage Devices Using Paul Glaucoma Implant.

Aim And Background: To describe a novel and uncomplicated technique of elongating the tubing of a glaucoma drainage device (GDD) sourced from a segment of the tube from a Paul® Glaucoma Implant (PGI).

Surgical Technique: Conjunctival and Tenon's peritomy are performed with relaxing incisions to expose the original tube. The original tube is then removed from the anterior chamber, and the original entry site is closed.

Canaloplasty and Trabeculotomy Using the OMNI Surgical System in Three Patients with Angle Closure: A Case Series.

Aim And Background: The OMNI surgical system allows for 360° canaloplasty and trabeculotomy for patients with glaucoma, either as a standalone procedure or in combination with cataract surgery. There is currently limited evidence on its use in forms of angle-closure glaucoma, though other microinvasive glaucoma surgeries have been used. We present three patients with angle closure who underwent the procedure.

Minimally Invasive Tube Surgery (MITS)-A Novel Method in Glaucoma Drainage Device Implantation.

: We introduce a new surgical technique for inserting the eyePlate-300-a glaucoma drainage device (GDD). The flexibility of the eyePlate-300 allows for folding and insertion through a smaller conjunctival incision. The procedure is termed minimally invasive tube surgery (MITS).

Flow characterization and structural alterations in Ahmed glaucoma FP7 tubes after in-vitro aging in silicone oil.

Purpose: Patients with intraocular silicone oil (SO) display higher odds of surgical failure after Ahmed glaucoma valve (AGV) implantation compared to patients without SO. However, the structural impact of SO exposure on silicone-made AGV tubes and the resulting changes in flow rate remain unexplored. This in-vitro study evaluated changes in tube dimensions and flow rates of AGV FP7 tubes after SO exposure to inform clinicians how such changes may impact AGV functionality.

Efficacy of XEN gel stent implantation combined with mitomycin C injection in the treatment of open-angle glaucoma: a meta-analysis.

Objective: To assess the efficacy of XEN gel stent implantation combined with mitomycin C (MMC) injection in controlling intraocular pressure (IOP) and the dosage of postoperative medication for open-angle glaucoma (OAG) patients.

Methods: The PubMed, Embase, Cochrane Library, and Science Direct databases were searched from inception to August 2022 without any language restriction. All studies that compared IOP and the dose of medication before and after XEN gel stent implantation and MMC injection for OAG patients were included.

Long-term surgical outcomes of combined Ahmed glaucoma valve implantation and phacoemulsification with intraocular lens implantation for patients with glaucoma secondary to iridocorneal endothelial syndrome.

Background: To assess the long-term outcomes of patients with glaucoma secondary to iridocorneal endothelial syndrome (GS-ICE) who underwent Ahmed glaucoma valve (AGV) implantation combined with phacoemulsification and intraocular lens (IOL) implantation surgery.

Methods: In this non-comparative retrospective case series study, twelve patients with uncontrolled GS-ICE and cataract underwent Ahmed aqueous shunt combined with phacoemulsification and IOL implantation surgery at Beijing Tongren Eye Center between June 2014 and June 2022. Main medical records included best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of antiglaucoma medications (AGM), corneal status and further surgical interventions.

Trends in glaucoma surgery in a tertiary hospital in Spain: 2010-2022.

Objective: This study aims to conduct an analysis glaucoma surgeries performed over a 13-year period at a tertiary hospital affiliated with the Spanish National Health System, with the goal of assessing temporal trends.

Methods: This retrospective observational study scrutinized surgeries undertaken in the glaucoma unit of a tertiary center in Spain between 2010 and 2022. Data collected included surgical dates, procedure performed, whether it was standalone or combined, as well as patient demographics including age, sex, and type of underlying glaucoma.

Pupillary Peaking & Presence of Dysphotopsias Following Glaucoma Tube Shunt Surgery.

Purpose: To describe the presence of pupillary peaking and dysphotopsias in a sample of eyes following glaucoma drainage device (GDD) surgery.

Methods: Cross-sectional analysis of 68 glaucoma patients with GDD, 45 patients with glaucoma and no GDD, and 50 control patients was conducted in a single academic center. Patients with an appropriate diagnosis that met the inclusion criteria were asked to enroll in the study.

Risk factors for receiving both scleral buckle and glaucoma drainage device in children.

We conducted a retrospective review of patients (< 18 years) between 2013 and 2021 to determine risk factors of pediatric patients receiving a glaucoma drainage device (GDD) needing a scleral buckle (SB) and vice versa. The first population underwent an SB placement with no prior GDD. The second underwent a GDD implantation with no prior SB.

Effectiveness and biocompatibility of a novel Schlemm's canal microstent for glaucoma management.

To evaluate the effectiveness and biocompatibility of Wistend, a novel Schlemm's canal (SC) microstent made of Nitinol designed to improve aqueous humor outflow. New Zealand white (NZW) rabbits were divided into blank, sham-operated and Wistend groups. ICare Tonovet Plus, swept-source optical coherence tomography (SS-OCT), slit lamp biomicroscopy, retinal camera and scanning electron microscopy (SEM) were used for preoperative and postoperative observations.

Intraocular Pressure Fluctuation as Assessed by Water Drinking Test following iStent Inject Implantation in Open-Angle Glaucoma Patients.

Introduction: This study investigated the intraocular pressure (IOP) fluctuation as assessed by the water drinking test (WDT) in open-angle glaucoma (OAG) patients after combined cataract surgery with iStent implantation.

Methods: This was a prospective non-randomized comparative study. Eyes with OAG and cataracts that were planned for either combined phacoemulsification and iStent implantation (iStent+CS) or phacoemulsification alone (CS) were recruited.

Use of double short tandem scleral tunnels for repairing eroded ahmed glaucoma valve tubes.

Purpose: To evaluate the effectiveness and safety of a method for repairing an eroded Ahmed glaucoma valve (AGV) tube using two short scleral tunnels made in tandem with a 22G needle instead of covering the eroded tube with another scleral graft.

Methods: From May 12, 2015, to July 27, 2019, we retrospectively reviewed eight patients at Ningbo Aier Eye Hospital who developed AGV tube erosion secondary to necrosis of their overlying conjunctiva and scleral grafts. This defect was repaired in all the patients using the double short tandem scleral tunnel technique, which involved the creation of double short tandem scleral tunnels made by a 22G needle.
