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.

Xen-DS: a novel technique of ab externo Xen implantation augmented with a modified deep sclerectomy for surgical treatment of glaucoma.

Purpose: The Xen gel stent is a surgical glaucoma device which creates a subconjunctival filtering bleb, which has demonstrated good intraocular pressure (IOP) lowering and safety. Nonetheless, bleb-related problems have been reported. We present a case series of ab externo Xen procedures augmented with a deep intra-scleral lake, aiming to improve both IOP-lowering and post-operative management.

Our Experience of Deep Sclerectomy at a Tertiary Center in the United Kingdom Over 14 Years.

Background Deep sclerectomy (DS) is a non-penetrating surgical procedure for glaucoma, reducing the resistance to aqueous outflow and lowering intraocular pressure while maintaining a physiological barrier between the anterior chamber and the sub-scleral space. This offers a lower complication profile than penetrating procedures, though with less intraocular pressure (IOP) reduction. Methods We retrospectively reviewed the electronic record for all DS undertaken at our hospital (a tertiary care center) over 14 years, collecting data on demographics, diagnosis, IOP, visual acuity, complications, medications, and further procedures required.

Efficacy and Safety of Sutureless Trabeculectomy with Using Porous Collagen (Ologen) in Management of Glaucoma Patients.

Purpose: This study aims to investigate the safety, efficacy and feasibility of sutureless trabeculectomy using a porous collagen matrix that contains a connected porous structure (Ologen) in the control of intraocular pressure (IOP) in glaucoma patients .

Methods: The study includes 25 eyes from 24 patients that met the inclusion criteria. All eyes underwent trabeculectomy with the Ologen implant that provides a space with a dynamic and physiological aqueous reservoir system.

Deep Sclerectomy with Porous Collagen in Open-angle Glaucoma, Short-term Study.

Aim: To assess the role of porous collagen in deep sclerectomy (DS), with and without trabeculo-Descemet membrane (TDM) rupture.

Patients And Methods: Forty-six eyes with different types of open-angle glaucoma and medically uncontrolled intraocular pressure (IOP) were selected. DS was performed in all cases.
