MRI after successful eyeWatch(TM) implantation

André Mermoud, Nikolaos Stergiopoulos, Sylvain Roy, Adan Villamarin

The eyeWatch(TM) is a new glaucoma drainage device that includes an adjustable mechanism that can vary the resistance to aqueous humor outflow during the postoperative period to reduce the burden of postoperative intraocular pressure (IOP) management. The ...

EyeWatch Rescue of Refractory Hypotony After Baerveldt Drainage Device Implantation: Description of a New Technique

André Mermoud, Nikolaos Stergiopoulos, Adan Villamarin, Sina Elahi

The most effective way to control glaucoma is by lowering intraocular pressure (IOP) in order to prevent the progression of the disease. Glaucoma drainage devices (GDDs) are surgical option reserved for refractory cases and have been designed to address kn ...

A New Noninvasively Adjustable Glaucoma Drainage Device

Adan Villamarin

Glaucoma is an irreversible disease affecting the eye, leading to progressive loss of vision and eventually to total blindness. It is often related to high intraocular pressure (IOP), which results from increased outflow resistance to aqueous humor. The fi ...

3D simulation of the aqueous flow in the human eye

Nikolaos Stergiopoulos, Philippe Reymond, Sylvain Roy, Adan Villamarin, Reda Hasballa, Orestis Vardoulis

Glaucoma results in an increase in the resistance of the aqueous humor outflow, which in turn leads to an increase of the intraocular pressure (IOP). Several treatments are proposed to reduce and stabilize the IOP that include medications, filtering surger ...
