Acta Ophthalmologica, EarlyView.Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Acta Ophthalmologica, EarlyView.Abstract Purpose The Baerveldt glaucoma drainage implant (BGI 101–350) is one of the most effective treatment options for managing refractory glaucoma. To mitigate early hypotony in non‐valved implants, intraluminal occluding sutures (IOSs) are commonly used.

A New Adjustable Glaucoma Drainage Device
Investigative Opthalmology & Visual Science, 2014 This work is focused on the testing of a new experimental noninvasively adjustable glaucoma drainage device (AGDD) that allows for the control of its outflow resistance to modulate intraocular pressure (IOP) in a customized fashion.Six AGDDs were directly connected to a pressure transducer and a perfusion system continuously delivering saline solution ...

Development of a microstent system for minimally invasive glaucoma surgery
Current Directions in Biomedical Engineering, 2017 Glaucoma is the leading cause of irreversible blindness worldwide. An increased intraocular pressure (IOP) is known as major risk factor. Currently, drainage devices that are implanted by means of minimally invasive glaucoma surgery (MIGS) represent a ...

Acta Ophthalmologica, EarlyView.Abstract Purpose To assess the vision‐related quality of life (VRQoL) in glaucoma patients over 5 years after primary Baerveldt glaucoma implant (BGI) or trabeculectomy (TE) using a secondary analysis of a randomized clinical trial. Methods Patients were randomized to undergo TE or receive a BGI.

Acta Ophthalmologica, EarlyView.Abstract Purpose To evaluate bleb morphology longitudinally using sonography following glaucoma drainage device (GDD) surgery. Methods Prospective observational cohort study conducted from January 2022 to March 2024, with follow‐up up to 12 months postoperatively. Bleb morphology, including superior and inferior bleb height, transverse and longitudinal

Clinical outcomes of the PAUL® glaucoma implant for secondary glaucoma
Acta Ophthalmologica, EarlyView.Abstract Purpose Secondary glaucoma encompasses a broad spectrum of disease entities arising from diverse ocular pathologies and is often refractory to conventional treatment. Glaucoma drainage devices (GDDs) have therefore become an important surgical option.
