A total of 31 eyes from 28 patients received a MicroShunt implantation, and 29 eyes from 26 patients received a TET. Surgical success was defined as an intraocular pressure (IOP) between 5 mmHg and 17 mmHg at the end of the follow-up period, no need for surgical revisions or secondary glaucoma surgery, and no loss of light perception...

A 69-year-old male patient with Pseudoexfoliation and open angle glaucoma presented with malignant glaucoma 1 week after undergoing Gonioscopy Assisted Transluminal Trabeculotomy (GATT). This is a rare sight threatening complication following GATT. High index of suspicion, early detection and prompt institution of medical therapy and YAG hyaloidotomy, helped in resolution of the condition with good intra ocular pressure control and visual improvement.

BACKGROUND: Trabeculotomy with the Kahook knife is a new ab interno minimally invasive glaucoma surgery (MIGS) procedure. The MIGS are usually performed in early to intermediate glaucoma eyes. In this retrospective study we analyzed the intraocular pressure (IOP) and topical glaucoma eye drop therapy (Meds) reduction achieved by the Kahook trabeculotomy (TO) without (n = 19) or with (n = 18) combined cataract operation (Cat-TO) as initial treatment before or to avoid filtering surgery...

OBJECTIVES: The objectives of the study were to analyze the long-term results of trabectome surgery in Turkish patients with primary open angle glaucoma (POAG) and pseudoexfoliative glaucoma (PEXG) and to characterize the risk factors for failure. METHODS: This single-center retrospective non-comparative study included 60 eyes of 51 patients diagnosed with POAG and PEXG, who underwent trabectome alone or phacotrabeculectomy (TP) surgery between 2012 and 2016. Surgical success was defined as a 20% decrease in intraocular pressure (IOP) or IOP≤21 mmHg and no further glaucoma surgery...

PURPOSE: The aim of the underlying study was to present a new surgical method in PreserFlo MicroShunt surgery for glaucoma. A removable polyamide suture was placed into the lumen of the MicroShunt during implantation to prevent early postoperative hypotony.

PURPOSE: Pseudoexfoliation glaucoma (XFG) is often associated with a higher rate of intraoperative complications and failure. This study aims to compare the long-term clinical and surgical outcomes of cataract surgery alone versus combined surgery in XFG. THIS WAS A RETROSPECTIVE: comparative case series. METHODS: All patients with XFG who underwent either cataract surgery alone [group 1: either phacoemulsification, PHACO/small-incision cataract surgery (SICS), n = 35] or combined surgery (group 2: phacotrabeculectomy, PHACOT or SICS + trabeculectomy, n = 46) from 2013 to 2018 by a single trained surgeon were screened and recalled for a detailed clinical examination, including Humphrey visual field analysis at 3-monthly intervals for a minimum of 3 years...

INTRODUCTION: Conflicting results have been reported on phacoemulsification in the filtered eyes with open-angle glaucoma. In this study, we aim to compare the effect of phacoemulsification after trabeculectomy between pseudoexfoliation glaucoma (XFG) and primary open-angle glaucoma (POAG). METHODS: Consecutive patients with XFG and POAG who underwent uneventful phacoemulsification after trabeculectomy with 5-fluorouracil (TRAB-PHACO group) were reviewed retrospectively and matched to patients who underwent trabeculectomy only (TRAB group)...

PURPOSE OF REVIEW: Choroidal effusions are recognized as a common early postoperative complication of glaucoma surgery, and although often benign, they may cause significant ocular morbidity. This article aims to summarize current research on the risk factors and management of choroidal effusions. RECENT FINDINGS: Glaucoma drainage device (GDD) implantation and trabeculectomy are the most commonly performed surgeries for the management of moderate to severe glaucoma...

BACKGROUND: To evaluate and compare the visual function and the quality of life (QoL) in glaucomatous patients treated with topical medical therapy (TMT) alone, canaloplasty (CP), or trabeculectomy (TB). METHODS: A total of 291 eyes of 167 patients with primary open-angle glaucoma or secondary pseudoexfoliative glaucoma in TMT or surgically treated with CP or TB were included. Eligibility criteria for surgical patients included not needing TMT after surgery. Each patient underwent a visual field assessment and peripapillary retinal nerve fiber layer (pRNFL) optical coherence tomography and filled out the Glaucoma Symptoms Scale (GSS) questionnaire and the 25-Item National Eye Institute Visual Functioning Questionnaire (25-NEI-VFQ)...

INTRODUCTION: Glaucoma is a degenerative disease of the optic nerve and is marked by visual field defects (VFD). The only approved treatment is IOP lowering, either with eye drops, laser or surgery. Minimally invasive glaucoma surgery (MIGS) has become an appealing treatment modality, offering IOP lowering effect without the complication rates of trabeculectomy or the patient adherence required for pharmacologic therapy. In this study we aim to describe the severity of VFD in patients undergoing their first MIGS surgery...

Best-corrected visual acuity often decreases temporarily or permanently after trabeculectomy (TE). The purpose of this study was to compare visual acuity and refractive changes after TE or XEN microstent implantation (XEN) in primary open-angle glaucoma (POAG) or pseudoexfoliation glaucoma (PEX) cases naïve to prior glaucoma surgery over a 24-month follow-up period. We analyzed 149 consecutive glaucoma patients who received either TE or XEN because of medically uncontrollable POAG or PEX. Intraocular pressure (IOP), IOP-lowering medication use, subjective and objective refraction and best-corrected visual acuity were evaluated...

PURPOSE: To evaluate the safety and efficacy of Xen45 Gel stent (Xen; Allergan) in eyes that have failed prior surgical intervention, compared to traditional glaucoma drainage device (GDD) or continuous-wave cyclophotocoagulation (CPC). Since this population has low expected success rates with additional surgery, it is vital to compare to standard-of-care surgical options. METHODS: Retrospective, single-center, case-control study of ab externo transconjunctival Xen shunt in eyes that have previously undergone trabeculectomy and/or GDD surgery...

Purpose: The aim is to evaluate the effect of amniotic membrane transplantation (AMT) on trabeculectomy with mitomycin C in patients with pseudoexfoliation glaucoma (PXG). Methods: This retrospective cohort study included 85 eyes of PXG who underwent trabeculectomy with or without AMT (52/33 eyes in the AMT/control group). Surgical success was defined by these criteria: (1) intraocular pressure (IOP) ≤18 mmHg and IOP reduction ≥20% and (2) IOP ≤15 mmHg and IOP reduction ≥25%...
