Comparison of Outcomes of Deep Sclerectomy, Canaloplasty, and Viscocanaloplasty: A Multi-Centred Study.

Prcis: Deep sclerectomy (DS) and canaloplasty provide better intraocular pressure (IOP) control than viscocanalostomy. DS required less glaucoma medications but more interventions to reach target IOP.

Purpose: To compare real-world outcomes of three non-penetrating glaucoma surgery (NPGS) techniques.

Anterior segment OCT for imaging PAUL glaucoma implant patch grafts: a useful method for follow-up and risk management.

Aim: To evaluate a useful, non-contact method for the follow-up of pericardium patch graft changes in patients undergoing PAUL Glaucoma Implant (PGI) surgery using high-resolution anterior segment optical coherence tomography (OCT) to predict tube erosions.

Methods: Prospective analysis over six months of tube pericardium patch graft thickness of PGI surgical cases at the University Eye Hospital Bonn, Germany, from November 2021 to August 2022. In all eyes, Tutopatch (RTI Surgical, United States) pericardium was used to cover the implant intra-operatively.

Minimally Invasive Glaucoma Surgery.

Background: Approximately 1.4 % of the German population aged 35 to 74 suffers from glaucoma, which is one of the more common causes of blindness. The only evidence-based treatment option at present is lowering the intraocular pressure.

Factors influencing the outcomes of trabeculectomy, conventional canaloplasty, and mitomycin C augmented canaloplasty.

Purpose: To compare the efficacy, safety, and factors influencing the outcomes of trabeculectomy (TE), conventional canaloplasty (cCP), and mitomycin C augmented canaloplasty (mCP) in glaucoma patients.

Methods: Intraocular pressure (IOP), the number of IOP-lowering eye drops, and surgery-related complications were evaluated at baseline and through 18 months postoperatively. Correlations between patients' demographic data, ophthalmic and non-ophthalmic conditions, outcomes and complications were evaluated.

[Glaucoma drainage devices in patients following injector-assisted implantation of an artificial iris into the ciliary sulcus : Video article].

Objective Of Surgery: The aim of this surgical technique is the implantation of a glaucoma drainage device (GDD) in eyes with aphakic glaucoma following injector-assisted implantation of an artificial iris into the ciliary sulcus.

Indications: This atraumatic tube insertion technique can be performed during GDD implantation after implantation of an artificial iris into the ciliary sulcus.

Surgical Technique: Following injector-assisted implantation of an artificial iris into the ciliary sulcus of eyes, the iris can shift into the chamber angle.

Proteomic and Cytokine Profiling in Plasma from Patients with Normal-Tension Glaucoma and Ocular Hypertension.

Primary open-angle glaucoma (POAG) is subdivided depending on eye pressure. Patients with normal-tension glaucoma (NTG) have never had high intraocular pressure (IOP) measured while patients with ocular hypertension (OHT) have high eye pressure but no signs of glaucoma. Although IOP is considered to be a risk factor for all glaucoma patients, it is reasonable to assume that other risk factors such as inflammation play a role.

The Effect of Trabecular Aspiration on Intraocular Pressure, Medication and the Need for Further Glaucoma Surgery in Eyes with Pseudoexfoliation Glaucoma.

Purpose: To investigate whether trabecular aspiration (TA) has an effective medium-term intraocular pressure (IOP)-lowering and medication-saving effect in patients with pseudoexfoliation glaucoma (PEG). In addition, a subgroup analysis of patients with or without a previous trabeculectomy was performed.

Methods: Records of 290 consecutive eyes with PEG that underwent TA between 2006 and 2012 at the Department of Ophthalmology, Mainz, Germany, were retrospectively analyzed with a follow-up period of 3 years.

Pathological high intraocular pressure induces glial cell reactive proliferation contributing to neuroinflammation of the blood-retinal barrier via the NOX2/ET-1 axis-controlled ERK1/2 pathway.

Background: NADPH oxidase (NOX), a primary source of endothelial reactive oxygen species (ROS), is considered a key event in disrupting the integrity of the blood-retinal barrier. Abnormalities in neurovascular-coupled immune signaling herald the loss of ganglion cells in glaucoma. Persistent microglia-driven inflammation and cellular innate immune system dysregulation often lead to deteriorating retinal degeneration.

The Impact of Aging on the Function of Retinal Ganglion Cells.

Aging is a major risk factor for retinal neurodegenerative diseases. Aged mammalian retinal ganglion cells (RGCs) lack the ability to regenerate axons after injury. Rodent models suggest that older age increases the vulnerability of RGCs to injury and impairs RGC function as well as their functional recovery.

Cytokine Profiling in Aqueous Humor of Glaucoma Patients and in Retinas from an Glaucoma Animal Model.

Background: Although the current role of cytokines and neuroinflammation in glaucoma remains obscure, it represents an expanding field in research. The purpose of this study was to analyze cytokines in the aqueous humor (AH) of glaucoma patients and in retinas from an glaucoma animal model, to aid in determining the role of neuroinflammation in glaucoma.

Methods: AH samples were collected from 20 patients during cataract surgeries (controls: n = 10, age = 70.

Mid-term real world outcomes of the Hydrus Microstent in open angle glaucoma.

Purpose: To evaluate the mid-term clinical results and the safety aspects of the Hydrus Microstent (Ivantis, Inc, Irvine, CA) in a real-life setting.

Design: Retrospective case series.

Methods: Hydrus Microstent was implanted in phakic eyes (88 eyes, 87.

European Glaucoma Society research priorities for glaucoma care.

Background/aims: The goal of health research is to improve patients care and outcomes. Thus, it is essential that research addresses questions that are important to patients and clinicians. The aim of this study was to develop a list of priorities for glaucoma research involving stakeholders from different countries in Europe.

Efficacy of citicoline as a supplement in glaucoma patients: A systematic review.

Purpose: Glaucoma is a leading cause of irreversible blindness worldwide. Retinal ganglion cells (RGC), the neurons that connect the eyes to the brain, specifically die in glaucoma, leading to blindness. Elevated intraocular pressure (IOP) is the only modifiable risk factor, however, many patients progress despite excellent IOP control.

The Association between Vascular Abnormalities and Glaucoma-What Comes First?

Glaucoma is a leading cause of irreversible blindness worldwide. While intraocular pressure (IOP) presents a major risk factor, the underlying pathophysiology still remains largely unclear. The correlation between vascular abnormalities and glaucoma has been deliberated for decades.

[Comparison of new and old procedures in glaucoma surgery : Trabeculectomy, Preserflo and XEN].

Glaucoma is one of the most frequent causes of irreversible blindness worldwide. The main risk factor of the disease is an individually too high intraocular pressure and pressure reduction is still the only established treatment. If conservative pressure reduction and adherence are insufficient, and if the patient is unable to tolerate conservative treatment, surgical procedures become necessary.

Long-Term Efficacy and Safety of Modified Canaloplasty Versus Trabeculectomy in Open-Angle Glaucoma.

Background: To evaluate the long-term efficacy and safety of modified canaloplasty versus trabeculectomy in open-angle glaucoma.

Methods: In total, 210 subjects with open-angle glaucoma were included. 70 were treated with Mitomycin C-augmented modified canaloplasty with enhanced subconjunctival filtration and 140 with Mitomycin C-augmented trabeculectomy.

Intraocular Pressure-Induced Endothelial Dysfunction of Retinal Blood Vessels Is Persistent, but Does Not Trigger Retinal Ganglion Cell Loss.

Research has been conducted into vascular abnormalities in the pathogenesis of glaucoma, but conclusions remain controversial. Our aim was to test the hypothesis that retinal endothelial dysfunction induced by elevated intraocular pressure (IOP) persists after IOP normalization, further triggering retinal ganglion cell (RGC) loss. High intraocular pressure (HP) was induced in mice by episcleral vein occlusion (EVO).
