Brown Glaucoma Implant
Brown Glaucoma Implant: The Brown Glaucoma Implant (BGI) is an implantable device designed to lower intraocular pressure (IOP) in glaucoma patients by shunting aqueous humor from the anterior chamber of the eye to the surface of the eye. Because there are no physiologic sources of outflow resistance, the device can be engineered to target an IOP that is low enough to halt the progression to blindness in a patient suffering from glaucoma.
