DESIGN: Single-center, retrospective, comparative case series. PARTICIPANTS: A total of 90 patients underwent surgical treatment, including 45 patients in the phaco-tube group and 45 patients in the phaco-trab group. METHODS: Eligible patients were identified using current procedural terminology (CPT) codes, and their medical records were retrospectively reviewed...

Excessive wound healing in filtering glaucoma surgery is a key factor for a failed surgery. After the introduction of trabeculectomy in the 1960s many factors associated with an increased fibrotic reaction were recognized and methods were developed to influence postoperative wound healing. These range from the perioperative use of anti-inflammatory drugs and antimetabolites to the use of newer chemical compounds that influence the morphology of postoperative fibroblast growth. In the routine clinical practice, the fine tuning of therapeutic decisions plays a decisive role in the success or failure of filtration surgery...

BACKGROUND: Neovascular glaucoma (NVG) is an irreversible blinding eye disease worldwide and is classified as one of the refractory glaucoma conditions, severely impacting visual function and vision. Unfortunately, effective surgical interventions to improve the prognosis of NVG patients are currently lacking. The study aims to evaluate the efficacy and safety of anterior chamber proliferative membrane interception (AC-PMI)-enhanced trabeculectomy compared to the traditional trabeculectomy...

Glaucoma is one of the world's leading causes of irreversible vision loss. It is often asymptomatic until it reaches an advanced stage, which can have a significant impact on patients' daily lives. This paper describes the case of a 50-year-old female patient who presented with acute onset of ocular pain, photophobia, and loss of visual acuity in her right eye (RE). The patient's medical history includes congenital cataracts, surgical aphakia, nystagmus, strabismus, amblyopia, and secondary glaucoma. Ophthalmological examination showed BCVA RE-hand movement, left eye (LE)-0...

AIM: To retrospectively evaluate the effectiveness and reliability of selective laser trabeculoplasty (SLT) treatment in juvenile open angle glaucoma (JOAG) cases. MATERIAL AND METHOD: The 46 eyes of 28 cases that had undergone SLT for JOAG and had a follow-up of at least one month were included in the study. The pre-SLT, month 1, month 6, year 1, year 2, and final follow-up intraocular pressure (IOP); the number of drugs before and after the SLT procedure; and the complications caused by the SLT were recorded...

PURPOSE: The effectiveness of mitomycin C (MMC) in trabeculectomy has long been established. The aim of this review is to evaluate the efficacy and safety of adjunctive agents in tube shunt drainage device surgery for glaucoma or ocular hypertension, since controversy still exists regarding their benefit. METHODS: We searched CENTRAL, PubMed, Embase, Web of Science, Scopus, and BASE for RCTs, which have used adjuvant antimetabolites-either MMC or 5-Fluorouracil (5-FU)-and/or anti-vascular endothelial growth factors (anti-VEGF) agents...

PURPOSE: To determine vision-related quality of life (VR-QoL) and functional and structural parameters associated with VR-QoL in patients with glaucoma before and 12 months after trabeculectomy. METHODS: Fifty-eight patients undergoing trabeculectomy were included. Participants completed the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) prior to and 12 months after trabeculectomy. Functional (visual acuity and visual fields) and structural (ganglion cell layer volume) parameters were evaluated for their association with VR-QoL using multiple linear regression of VFQ-25 subscale scores...

BACKGROUND: Ocular surface disorder after ocular radiation therapy, even though commonly reported, is often overlooked. Any delay in diagnosis may lead to complications that threaten vision. The presented case highlights the clinical outcome of a severe post-radiation disorder of the ocular surface, the importance of intensive therapy, and the limitations of further surgical interventions. CASE PRESENTATION: A 34-year-old woman was referred for a second opinion due to a years-long history of pain and redness in her right eye (OD) after proton beam therapy for recurrent iris melanoma...

The PRESERFLO™ MicroShunt (MP; Santen Inc., Osaka, Japan) is a minimally invasive bleb surgery (MIBS) manufactured to treat primary open-angle glaucoma (POAG), with lower postoperative adverse effects than with conventional filtering surgeries. We describe here the case study of a 58-year-old woman who presented with bilateral severe myopia with bilateral advanced POAG and unreached target pressure under quadritherapy, who was successfully managed by PM surgery. A review of the literature completes our observation...

Age is an important risk factor for both glaucoma and cataract. As global life expectancy continues to rise, the prevalence of concomitant open-angle glaucoma (OAG) and cataracts is increasing. Currently, there is a lack of definitive consensus on the optimal management approach for such individuals. Conventionally, trabeculectomy (Trab) in combination with phacoemulsification is the preferred method. Recent developments in microinvasive glaucoma surgery (MIGS), which offer similar results with fewer complications, provide a new possible approach to this condition...

PURPOSE: Compare outcomes of tube shunt surgery (Tube) and trabeculectomy with Mitomycin C (Trab-MMC) in patients with angle-closure glaucoma (ACG). DESIGN: Retrospective, nonrandomized comparative study. SUBJECTS: A total of 80 eyes from 80 patients with ACG who underwent either Tube (N = 50) or Trab-MMC (N = 30) between January 2015 and January 2022 at Massachusetts Eye and Ear. METHODS: Reviewed and analyzed 390 visits from patient charts...

PURPOSE: The success of XEN Gel Stent (XEN) and Preserflo MicroShunt (Preserflo) implantation depends mainly on the development of bleb fibrosis. This study aimed to describe the histological findings of bleb fibrosis after XEN and Preserflo surgery. METHODS: This retrospective study included patients with different types of glaucoma who underwent revision surgery after XEN or Preserflo implantation. The available clinical information and histological samples of removed fibrotic tissue were analyzed...

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...

BACKGROUND: Glaucoma is a progressive optic neuropathy and it is the main cause of irreversible blindness worldwide. Intraocular pressure (IOP) is the only modifiable one and trabeculectomy is commonly considered the surgical "gold standard" to decrease IOP. In particular cases, other kind of surgeries, as the Ahmed Glaucoma Valve (AGV) implant, are a reliable alternative. Usually, the silicone tube of AGV surgery is inserted into the anterior chamber. Sometimes it is necessary to place the AGV silicone tube in the ciliary sulcus, especially in cases of endothelial decompensation...

PURPOSE: To report a case of phacolytic glaucoma with atypical presentation in a patient which was diagnosed with biometry swept source optical coherence tomography (SS-OCT) and anterior segment spectral domain OCT (SD-OCT). METHODS: A 56-year-old male with a history of cytomegalovirus (CMV) chronic anterior uveitis in the right eye presented with a white cataract, minimal anterior chamber reaction and intraocular pressure (IOP) of 56 mmHg. Visual acuity was light perception...

Background : To evaluate changes in the visual field (VF) after Descemet stripping automated endothelial keratoplasty (DSAEK) in eyes with advanced glaucoma and previous trabeculectomy. Methods : Changes in VF, best-corrected visual acuity (BCVA), intraocular pressure (IOP), and number of glaucoma medications were analyzed before and after DSAEK in 19 eyes. The VFs were evaluated using the 10-2 program of the Humphrey Field Analyzer (HFA) and/or Goldmann perimetry (GP). Results : In nine eyes, the MD improved from -22...

Glaucoma is a common and potentially blinding complication of uveitis. Many mechanisms are involved alone or in combination in the pathogenesis of uveitic glaucoma (UG). In terms of diagnostic evaluation, the effects of inflammatory activity in the retinal nerve fiber layer may be a source of bias in the interpretation of optical coherence tomography measurements. For the successful treatment of UG, the control of intraocular inflammation specific to the cause or anti-inflammatory treatment, combined with IOP management, is mandatory...

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...
