Tube-shunt surgery or drainage implant surgery involves the placement of a tube or glaucoma valves to facilitate aqueous outflow from the anterior chamber. [ 41 ] [ 46 ] [ 47 ] Trabeculopuncture uses a Q switched Nd:YAG laser to punch small holes in the trabecular meshwork.
The first glaucoma drainage implant was developed in 1966. [2] Following on the success of the Molteno implant, several varieties of device have been developed from the original, the Baerveldt tube shunt, or the valved implants, such as the Ahmed glaucoma valve implant and the later generation pressure ridge Molteno implants.
The Hydrus Microstent is an implantable MIGS device for the treatment of primary open angle glaucoma; implantation of this device can be performed in conjunction with cataract surgery. [30] The Hydrus Microstent is the longest of the MIGS devices (8-millimeter long implant), and similar to the iStent it is designed to increase trabecular outflow.
Trabectome surgery has also proven to be a valuable adjuvant at the point of both valved and non-valved tube shunt implantation. When comparing patients undergoing Baerveldt tube implantation alone with those undergoing the same procedure combined with trabectome surgery, both groups showed similar intraocular pressure and visual acuities after ...
Trabeculectomy is the most common invasive glaucoma surgery. It is highly effective in the treatment of advanced glaucoma as demonstrated in major glaucoma studies. [citation needed] Even if a prior trabeculectomy has failed a second trabeculectomy can be performed at a different site. If scarring is the main reason, anti-fibrotic and anti ...
Treatment typically includes prescription of eye drops, medication, laser treatment or surgery. [1] [9] The goal of these treatments is to decrease eye pressure. [2] Glaucoma is a leading cause of blindness in African Americans, Hispanic Americans, [10] [11] and Asians. [12]
