Comparison of efficacy and safety between gonioscopy-assisted transluminal trabeculotomy and trabeculectomy for primary open-angle glaucoma treatment: a retrospective cohort study.

Background: Trabeculectomy (TRAB) traditionally has been the gold-standard surgical treatment for primary open-angle glaucoma (POAG), while gonioscopy-assisted transluminal trabeculotomy (GATT) is an emerging minimally invasive surgery used for the treatment of various open-angle glaucoma (OAG) types. In this study, we aimed to compare the efficacy and safety between GATT and TRAB for the treatment of POAG.

Methods: This cohort study included eyes with POAG that underwent a single GATT (30 eyes) or TRAB (34 eyes).

Bleb Reformation After Lateral Cantholysis in a Case of Prostaglandin-associated Periorbitopathy.

An 84-year-old male with uncontrolled intraocular pressure (IOP), despite maximum topical medications including prostaglandin F2α analog, had bilateral prostaglandin-associated periorbitopathy-related tight upper eyelids. One day after trabeculectomy of the left eyelid, IOP was 24 mm Hg, with a flat bleb. Daily ocular massage failed to maintain bleb filtration.

Color Doppler Imaging Assessment of Ocular Blood Flow Following Ab Externo Canaloplasty in Primary Open-Angle Glaucoma.

: Glaucomatous neuropathy, a progressive deterioration of retinal ganglion cells, is the leading cause of irreversible blindness worldwide. While elevated intraocular pressure (IOP) is a well-established modifiable risk factor, increasing attention is being directed towards IOP-independent factors, such as vascular alterations. Color Doppler imaging (CDI) is a prominent technique for investigating blood flow parameters in extraocular vessels.

Effectiveness and safety of VISULAS® green selective laser trabeculoplasty: 12 months retrospective data.

To report the safety and effectiveness of selective laser trabeculoplasty (SLT) using the SLT mode of the VISULAS green laser in patients with primary open-angle glaucoma (POAG). Twelve months results are presented. Retrospective extension in 4 German centers of an initially prospective interventional multicenter 3-month clinical investigation using the VISULAS green SLT (Carl Zeiss Meditec AG, Jena, Germany) in patients with POAG who either needed treatment escalation or commenced treatment and had an IOP ≥ 17mmHg at baseline, with no previous glaucoma or other ocular surgery.

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.

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.

The Effect of Trabeculectomy on Disc Tissue Blood Flow Across Quadrants in Open-Angle Glaucoma.

Prcis: Trabeculectomy increases tissue blood flow superior and temporal in the optic nerve head. Improvement of tissue blood flow superior and temporal in the optic nerve could be an indicator of the effectiveness of glaucoma treatment.

Purpose: To investigate changes in tissue blood flow at the optic nerve head before and after trabeculectomy.

Ahmed Glaucoma Valve Implantation in Jordan: Indications and Complications.

Aim: The main indications for Ahmed glaucoma valve (AGV) include neovascular glaucoma, congenital glaucoma, primary open angle glaucoma and patients with failed previous trabeculectomy. This article aims to investigate the complications of AGV in Jordanian glaucoma patients and to justify the main risk factors.

Methods: Retrospectively, we report 87 eyes of 83 patients who underwent AGV implantation for different indications.

[Glaucoma drainage devices: Indications, intraoperative management and postoperative follow-up].

Glaucoma drainage devices (GDD) are used for patients with secondary glaucoma, such as uveitic or neovascular glaucoma, which is uncontrolled under local therapy. They are also used in patients with conjunctival scarring, for example after a previous vitrectomy or after unsuccessful previous glaucoma surgery, such as trabeculectomy. They are also a treatment option for congenital glaucoma, aphakic glaucoma or for the treatment of iridocorneoendothelial syndromes.

Distinctive Intrableb Structures of Functioning Blebs following Trabeculectomy according to Amniotic Membrane Transplantation.

Introduction: Intrableb structures are hallmark features of the filtering bleb. This study aimed to compare the characteristics of functioning blebs using anterior segment optical coherence tomography (AS-OCT) according to amniotic membrane transplantation (AMT).

Methods: Forty eyes from 40 patients diagnosed with primary open-angle glaucoma who underwent trabeculectomy, either with AMT (20 eyes) or without AMT (control group, 20 eyes), were included.

A lacrimal drainage pathway disease-associated keratopathy (LDAK) case with non-infectious endophthalmitis.

Purpose: To report a case of lacrimal drainage pathway disease-associated keratopathy (LDAK) with endophthalmitis.

Observations: An 80-year-old man with diabetic retinopathy and nephropathy was referred to our hospital with endophthalmitis of the left eye. Slit-lamp examination revealed slight eye discharge, peripheral corneal ulcers, diffuse hyperemia of the conjunctiva, iris synechia, and a large amount of fibrin in the anterior chamber of the left eye.

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.

Cystoid macular oedema: a rare complication following selective laser trabeculoplasty.

A female patient with previous vitrectomy for epiretinal membrane in the left eye underwent bilateral selective laser trabeculoplasty (SLT) for pigmentary glaucoma and subsequently developed cystoid macular oedema (CMO) in the vitrectomised eye. This resolved fully with treatment with topical steroids and non-steroidal anti-inflammatory drug (NSAID) drops. This complication has been very rarely reported in the literature, and a subsequent internal audit found a very low rate of CMO temporally related to SLT of 0.

Three-year outcomes of surgical bleb revision with mitomycin C for early scarring bleb after trabeculectomy.

Purpose: To report the 3-year outcomes of surgical bleb revision (SBR) with mitomycin C (MMC) for early scarring bleb after trabeculectomy (TLE).
