Trabeculectomy outcome

PURPOSE: This study aimed to evaluate the prognostic factors affecting surgical outcomes, including visual acuity (VA) improvement, after glaucoma surgery in patients with neovascular glaucoma (NVG). METHODS: The medical records of 116 patients (116 eyes) with NVG who had undergone trabeculectomy or Ahmed glaucoma valve implantation were reviewed retrospectively. The primary outcome measure was surgical success at 6 postoperative months, defined as sufficient intraocular pressure (IOP) reduction (IOP ≤21 mmHg, ≥20% reduction, regardless of topical medication use) without additional glaucoma surgery, hypotony, or progression to no light perception...

PRECIS: Analysis of surgical success and intraocular pressure (IOP), best-corrected visual acuity (BCVA) and antiglaucomatous medication (AGM) changes between segmental 180-degree and 360-degree gonioscopy-assisted transluminal trabeculectomy (GATT) in patients with pseudoexfoliation glaucoma (PEXG) showed no significant difference. PURPOSE: To compare surgical outcomes of segmental 180-degree and 360-degree GATT in PEXG patients. MATERIALS AND METHODS: Prospective, comparative study of 65 PEXG eyes, who underwent segmental 180-degree GATT (GATT 180° group, 31 eyes) and 360-degree GATT (GATT 360° group, 34 eyes) in a tertiary academic center over a 12-month of follow-up...

AIMS AND BACKGROUND: Delayed suprachoroidal hemorrhage (DSCH) is a vision-threatening complication of intraocular surgeries with a higher prevalence in postglaucoma filtering surgeries. Through these case series of trabeculectomy complicated with DSCH, we aim to emphasize that correction of hypotony (inciting factor) is fundamental for complete resolution and prevention of recurrence. CASE DESCRIPTION: All three glaucoma patients underwent trabeculectomy surgery followed by DSCH on postoperative day 1...

PURPOSE: To describe visual field outcomes in the Primary Tube Versus Trabeculectomy (PTVT) Study. DESIGN: Cohort analysis of a prospective multicenter randomized clinical trial. SUBJECTS: A total of 155 eyes from 155 subjects randomly assigned to treatment with tube shunt surgery (n=84) or trabeculectomy with mitomycin C (n=71). METHODS: The PTVT Study was a multicenter randomized clinical trial comparing the safety and efficacy of trabeculectomy and tube shunt surgery in eyes without prior intraocular surgery...

OBJECTIVE: To reliably compare the three-year clinical outcome and safety of XEN45 Gel Stent implantation (XEN) vs. trabeculectomy (TRAB) in patients with glaucoma. SUBJECT/METHODS: We conducted a retrospective cohort study with patients with primary open angle or pseudoexfoliation glaucoma with uncontrolled intraocular pressure (IOP) undergoing XEN or TRAB at the Innsbruck University Clinic of Ophthalmology and Optometry, Austria and analysed changes in IOP, numbers of IOP-lowering medications, and complete surgical success (i...

Background: The aim was to evaluate the long-term outcome and efficacy of primary trabeculectomy with adjunctive mitomycin c (MMC) for treating glaucoma. Methods: We examined the medical records of 286 eyes that underwent trabeculectomy between 2008 and 2009 at the University Eye Hospital in Freiburg, Germany. Preoperative and follow-up data were collected, including intraocular pressure (IOP) measurements, surgical glaucoma interventions, and prescribed glaucoma medication. The first success criterion was defined as IOP ≤ 15 mmHg with no use of pressure-lowering medication by the patient, the second criterion was defined as the absence of surgical revision, and the third criterion as no further IOP-lowering surgery excluding early revisions following trabeculectomy...

PRECIS: Our study highlights the long-term success of trabeculectomy or AGV surgery in subjects with glaucoma secondary to ICE syndrome. However, many of ICE syndrome cases may need multiple glaucoma surgeries to achieve controlled IOP, with/without concomitant corneal graft surgery. PURPOSE: To evaluate the long-term outcome of trabeculectomy and Ahmed glaucoma valve (AGV) implantation in iridocorneal endothelial syndrome (ICE). METHODS: Patients with glaucoma secondary to ICE syndrome who underwent either trabeculectomy or AGV surgery with intraoperative adjunctive MMC from 2009 to 2020 were included in this study...

PRECIS: In our case series, the three-year failure for PGI implantation was 14.6%. At three years post-operatively, there was a significant reduction in mean intraocular pressure and number of glaucoma medications used. PURPOSE: To determine 3-year efficacy and safety of the PAUL Glaucoma Implant (PGI), a novel glaucoma tube shunt in patients with glaucoma. METHODS: Retrospective review of all patients who had undergone PGI implantation in a single tertiary institution in Singapore between May 1, 2017, and Jan 1, 2022...

OBJECTIVE: To develop machine learning (ML) models, using pre and intraoperative surgical parameters, for predicting trabeculectomy outcomes in the eyes of patients with juvenile-onset primary open-angle glaucoma (JOAG) undergoing primary surgery. SUBJECTS: The study included 207 JOAG patients from a single center who met the following criteria: diagnosed between 10 and 40 years of age, with an IOP of >22 mmHg in the eyes on two or more occasions, open angle on gonioscopy in both eyes, with glaucomatous optic neuropathy, and requiring a trabeculectomy for IOP control...

INTRODUCTION: The XEN Gel, a hydrophilic tube meticulously crafted to adhere to the principles of the Hagen - Poiseuille law, is designed to facilitate efficient aqueous shunting without inducing hypotony. Implantable ab interno or ab externo, with or without conjunctival opening, the device shows no significant outcome differences. Despite numerical hypotony signaling failure, patients may fare well below 6 mmHg. AREAS COVERED: This review provides insights into device variability, challenges related to hypotony, associated risk factors, and hypotony management...

BACKGROUND: This study aimed to evaluate the clinical correlative factors and outcomes of treatment of bleb-associated endophthalmitis (BAE) following glaucoma filtration surgery in a Chinese population from the year 2012 to 2022, and to compare them with the clinical course during the coronavirus disease (COVID-19) pandemic period. METHODS: This was a retrospective analysis of consecutive cases of BAE treated at the Eye & ENT Hospital of Fudan University, Shanghai, China, between January 1, 2012, and December 31, 2022...

BACKGROUND: Neovascular glaucoma (NVG) is a secondary glaucoma with a poor visual prognosis. Trabeculectomy with antifibrotic agents, glaucoma drainage devices (GDDs), and cyclo-destructive procedures are recommended in patients who are refractory to medical management. However, due to the poor success rate of conventional trabeculectomy and the higher cost of GDDs, alternative procedures need to be looked at. PURPOSE: To compare the surgical outcomes and economic aspects of a newly developed polypropylene suture bed-based modified trabeculectomy to Ahmed glaucoma valve (AGV) implantation for NVG...

PURPOSE: Uveitis can lead to secondary glaucoma, a condition with challenging management that can carry irreversible visual loss. Filtering surgery has demonstrated a higher failure rate, increased incidence of postoperative complications and reinterventions in uveitic patients. There is no consensus on the optimal surgical approach for uveitic glaucoma (UG) due to limited data comparing various intraocular pressure (IOP)-lowering surgeries. This retrospective cohort aims to assess the clinical outcomes of trabeculectomy (TBT), non-penetrating deep sclerectomy (NPDS), Ex-PRESS shunt and Ahmed glaucoma valve, providing additional insights into the long-term IOP control and safety of filtering surgeries in UG...

AIM: To report on the outcome of subsequent interventions after failed initial intervention for primary congenital glaucoma (PCG). METHODS: Retrospective chart review of children presenting with PCG and failed the initial glaucoma surgery in Alexandria Main University Hospital from 2005 to 2017. The data included demographics, preoperative, operative and postoperative clinical characteristics. Success was defined as IOP<16mmHg and <20% from the presenting IOP and C/D ratio like or better than presentation...

To compare the safety and efficacy of the Preserflo Microshunt with trabeculectomy in the treatment of patients with glaucoma. A systematic review and meta-analysis was conducted. The primary outcome measures recorded as a measure of efficacy of the interventions were intra-ocular pressure (IOP) at final follow-up and IOP reduction (IOPR). Secondary outcomes recorded to measure efficacy were reduction in the number of glaucoma medications and reinterventions. To assess safety profile, the proportions of patients with post-operative complications were recorded...

This prospective randomized controlled trial aimed to compare the efficacy and safety of topical preservative-free diclofenac (DICLO) to dexamethasone (DEX) eyedrops, and their combination (DEX+DICLO) after trabeculectomy. Sixty-nine patients with medically uncontrolled glaucoma were randomized to receive topical postoperative treatment with DICLO ( n = 23), DEX ( n = 23), or a combination of DEX and DICLO ( n = 23). The primary outcome was the intraocular pressure (IOP) 12 months postoperatively. Secondary outcomes included surgical success, failure, visual field, and visual acuity from baseline to 12 months postoperatively...

BACKGROUND/AIMS: Advanced primary open angle glaucoma (POAG) is a lifelong condition. The aim of this study is to compare medical treatment against trabeculectomy for patients presenting with advanced POAG using an economic evaluation decision model. METHODS: A Markov model was used to compare the two treatments, medical treatment versus trabeculectomy for the management of advanced POAG, in terms of costs and quality-adjusted life-years (QALYs). The uncertainty surrounding the model findings was assessed using probabilistic sensitivity analysis and deterministic analysis...

BACKGROUND: Glaucoma is the term for a group of eye disorders that causes progressive damage to the optic nerve, which can lead to visual impairment and, potentially, irreversible blindness. Minimally invasive bleb surgery (MIBS) reduces eye pressure through the implantation of a device that creates a new subconjunctival outflow pathway for eye fluid drainage. MIBS is a less invasive alternative to conventional/incisional glaucoma surgery (e.g., trabeculectomy). We conducted a health technology assessment of MIBS for people with glaucoma, which included an evaluation of effectiveness, safety, the budget impact of publicly funding MIBS, and patient preferences and values...

PURPOSE: To compare the safety and efficacy of two different application methods of mitomycin C (MMC)-soaked sponge in trabeculectomy. STUDY DESIGN: Retrospective study. METHODS: We included 71 eyes of 71 patients that had undergone trabeculectomy. In the anterior scleral application group, 36 eyes were treated using the long side of the MMC-soaked sponge placed parallel to the limbus. The efficacy and safety in these eyes were compared with eyes treated with the posterior scleral application group, consisting of 35 eyes treated with the long side of the MMC-soaked sponge placed perpendicular to the limbus...

BACKGROUND: The 30-day readmission rate provides a standardised quantitative evaluation of some postoperative complications. It is widely used worldwide in many medical and surgical specialities, and the World Health Organization recommends its use for monitoring healthcare system performance. In ophthalmology, its measurement is biased by the frequent and close planned surgery on one eye and then the other, particularly in the case of cataract surgery. This study measures the 30-day unplanned readmission rate in ophthalmology, globally and by surgery subtype, and describes the causes of readmission...
