Immediate IOP Reduction for All Types of Refractory Glaucoma. The Ahmed Glaucoma Valve immediately reduces and controls pressure with its unique flow restrictor. This device also reduces the risk of hypotony at low pressures. Designed to Prevent Excessive Drainage.

Implantation of Ahmed glaucoma valve is an effective surgical technique to reduce intraocular pressure in patients affected with glaucoma. While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical ...

2024年7月4日 · The Ahmed Glaucoma Valve (AGV) is a medical implant designed to treat glaucoma, an eye condition characterized by increased intraocular pressure (IOP) that can damage the optic nerve and lead to vision loss.

Ahmed Glaucoma Valve The Venturi Effect: To reduce internal friction within the valve system, the Ahmed Glaucoma Valve utilizes a specially designed, tapered trapezoidal chamber to create a Venturi effect to help aqueous flow through the device. The inlet velocity of aqueous entering

What is glaucoma? What is the Ahmed® Glaucoma Valve and what does it do? This patient information leaflet serves to inform patients what to expect regarding the required care, precautions, and follow-up before and after Ahmed® Glaucoma Valve surgery. Glaucoma is an eye disease that damages the optic nerve of the eye. If glaucoma is not treat-

2024年6月26日 · The Ahmed Valve represents a significant advancement in the management of glaucoma, particularly for those who haven’t found success with other treatments. Designed to provide a consistent outflow of aqueous humor, this ingenious device helps to reduce intraocular pressure (IOP), thereby preventing damage to the optic nerve.

2024年7月4日 · Aqueous drainage devices, such as the Ahmed Glaucoma Valve, are engineered to regulate aqueous humor flow, the transparent fluid occupying the anterior chamber of the eye. These devices are frequently employed when conventional treatments like topical medications or laser procedures fail to adequately control intraocular pressure.

2025年1月27日 · Unique, non-obstructive valve system to prevent excessive drainage and chamber collapse. Implanted in a Single-stage procedure. Tapered profile for easy insertion. Aqueous percolation holes (FP7). Eliminates drainage tube ligature sutures, “rip-chord” sutures, and occluding sutures (FP8).

Ahmed glaucoma valve (AGV, New World Medical, Rancho Cucamonga, California) is a glaucoma drainage device that has a 184 mm 2 silicone plate and, as the name implicates, is equipped with a valve mechanism which reduce the incidence of early hypotony and hypotony related complications after surgery.

The Ahmed Glaucoma Valve, a drainage implant device, is one such innovative solution that ophthalmologists utilize in the treatment of glaucoma. By effectively diverting excess fluid from the eye, the valve helps to regulate intraocular pressure and …
