SD-OCT-histopathologic correlation in Schnabel's cavernous optic nerve atrophy.

Background: Until now, Schnabel's cavernous optic nerve atrophy (SCONA) has solely been a histopathological diagnosis exhibiting variable degrees of optic nerve (ON) atrophy with characteristic cavernous spaces filled with acid mucopolysaccharides. We report the first correlation of histopathologic findings with spectral domain-optical coherence tomography (SD-OCT) imaging in SCONA.

Methods: We examined the eye of an index patient with histopathologically identified SCONA who had undergone multimodal imaging before enucleation for iris ring melanoma.

Comparison of Outcomes of Deep Sclerectomy, Canaloplasty, and Viscocanaloplasty: A Multi-Centred Study.

Prcis: Deep sclerectomy (DS) and canaloplasty provide better intraocular pressure (IOP) control than viscocanalostomy. DS required less glaucoma medications but more interventions to reach target IOP.

Purpose: To compare real-world outcomes of three non-penetrating glaucoma surgery (NPGS) techniques.

Sonographic bleb visualisation after PAUL glaucoma implant surgery.

Background/aims: Bleb characteristics in the area around the plate following glaucoma drainage device (GDD) surgery are difficult to evaluate on slit lamp examination. Ultrasound sonography could be used for more detailed visualisation. The aim of this study was to describe bleb configuration after PAUL glaucoma implant (PGI) surgery and evaluate the possible correlation with intraocular pressure (IOP) in order to derive new markers for evaluating GDD function.

Anterior segment OCT for imaging PAUL glaucoma implant patch grafts: a useful method for follow-up and risk management.

Aim: To evaluate a useful, non-contact method for the follow-up of pericardium patch graft changes in patients undergoing PAUL Glaucoma Implant (PGI) surgery using high-resolution anterior segment optical coherence tomography (OCT) to predict tube erosions.

Methods: Prospective analysis over six months of tube pericardium patch graft thickness of PGI surgical cases at the University Eye Hospital Bonn, Germany, from November 2021 to August 2022. In all eyes, Tutopatch (RTI Surgical, United States) pericardium was used to cover the implant intra-operatively.

[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.
