Update on Tube-Shunt Procedures for Glaucoma
نویسنده
چکیده
Present-day glaucoma implants, i.e., long-tube implants, were introduced by Molteno et al. in 1976 [31]. !e most commonly used implants include Molteno and Ahmed singleand doubleplate implants, and the Baerveldt and Krupin implants. All implants are long-tube implants based on the original Molteno design. !e Ahmed and Krupin implants are valved implants. !e most recent addition to tube-shunt devices has been the Ex-Press shunt, a non-valved "ow restricting implant made of stainless steel, which is discussed later. !e basic concept of the long-tube implants is the creation of a #ltering bleb over the distal plate.

Update on Minimally Invasive Glaucoma Surgery (MIGS) and New Implants
Traditional glaucoma surgery has been challenged by the advent of innovative techniques and new implants in the past few years. There is an increasing demand for safer glaucoma surgery offering patients a timely surgical solution in reducing intraocular pressure (IOP) and improving their quality of life. The new procedures and devices aim to lower IOP with a higher safety profile than fistulati...

To evaluate the safety and efficacy of Trabectome after failed tube shunt surgery.Twenty patients with prior failed tube shunt surgery who underwent Trabectome alone were included. All patients had at least 3 months of follow-up. Outcomes measured included intraocular pressure (IOP), glaucoma medications, and secondary glaucoma surgeries.

متن کاملTrabeculectomy with internal tube shunt: a novel glaucoma surgery.
PURPOSE To describe a pilot study that evaluates the efficacy and mechanism of action of a new glaucoma operation, trabeculectomy with internal tube shunt. METHODS Twenty-three patients underwent the new operation in one eye for open angle glaucoma. Under a scleral flap, a deep sclerectomy was performed, resulting in an intrascleral lake. Laterally, on both sides, a small silicone tube was pl...
متن کاملGold shunt for refractory advanced low-tension glaucoma with spared central acuity
The aim of this study is to report a case of gold shunt surgery for uncontrolled, low-tension glaucoma with good central vision, after having a previously failed trabeculectomy and tube shunt surgeries. The patient was receiving maximum medical glaucoma therapy of four different types with intraocular pressure of 17 mm Hg prior to gold shunt surgery. Five years later, intraocular pressure is we...
