The ciliary body contains 72 protrusions known as ciliary processes, from which the aqueous is produced. The length of the Hydrus Microstent is thought to open approximately one quarter of Schlemm’s Canal, routing aqueous into open downstream collector channels. The largest investigation of endocyclophotocoaguation has shown a significant decrease in intraocular pressure of up to 10 mmHg, as well as a significant reduction in number of glaucoma medications needed. [31] The Hydrus Microstent takes advantage of this property by mechanically dilating and holding open Schlemm’s Canal. Standard glaucoma surgeries — trabeculectomy and ExPRESS shunts, external tube-shunts like the Ahmed and Baerveldt styles — are major surgeries. However, side effects of the transcleral approach can include significant inflammation, chronically low intraocular pressure, intraocular bleeding, and permanent shutdown of the eye, known as phthisis. The InnFocus Microshunt is a small tube, 8 mm in length, that is inserted in to the eye to help lower intraocular pressure and reduce the need for medications. Minimally invasive glaucoma surgery (MIGS) devices can be are employed in any glaucoma surgery that avoids conjunctival dissection, and includes an ab interno incision for the treatment of patients … The iStent Trabecular Micro-Bypass Stent, or simply iStent, is the smallest implantable medical device, designed to lower intraocular pressure by facilitating trabecular outflow of aqueous fluid. New developments in Micro-Invasive Glaucoma Surgery (MIGS) allow patients to have glaucoma and cataract surgery during one procedure, and most patients with a cataract and open-angle glaucoma … MIGS comprises a group of surgical procedures which share common features. [11][12] Safety of the iStent was comparable to cataract surgery alone which is much better than conventional trabeculectomy. [36], The InnFocus Microshunt has now been renamed the Preserflo.[37]. The first clinical data on the device was presented in 2010 showed sustained IOP lowering and MIGS-like safety profile. Stay up-to-date with the latest news about glaucoma, treatments, and research. MIGS has become a commonly used abbreviation in the glaucoma world. May 2016 issue of Gleams. Minimally invasive glaucoma surgery (MIGS) is a treatment approach focused on lowering eye pressure in order to prevent or reduce harm to the optic nerve. [32] The Hydrus Microstent is currently being investigated in an FDA approved study for mild-to-moderate glaucoma. Minimally invasive glaucoma surgery (MIGS) The new technologies and devices, known as MIGS, aim to lower IOP with a higher safety profile than fistulizing surgery (trabeculectomy/drainage … Currently, all therapy for glaucoma is directed at lowering eye pressure, but the fundamental problem in glaucoma is the degeneration of the optic nerve fibers necessary for vision. Minimally Invasive Glaucoma Surgery (MIGS) MIGS (Minimally Invasive Glaucoma Surgery) is another type of treatment for open-angle glaucoma. Micro-invasive glaucoma surgery (MIGS) is the latest advance in surgical treatment for glaucoma, which aims to reduce intraocular pressure by either increasing outflow of aqueous humor or reducing its production. [33] Unlike the latter two procedures, the XEN Gel Stent is performed through an internal approach and avoids directly incising and disrupting the conjunctiva itself.[34][35]. It is called MIGS, the acronym for minimally invasive glaucoma surgery, and it is the biggest development in glaucoma surgical treatment in many years. [8][9], The iStent is the first MIGS device to get FDA approval for implantation in combination with cataract surgery. [21], It has a microlumen of 300 microns and is designed to augment outflow to the suprachoroidal space in order to control intraocular pressure; it is indicated for the treatment of primary open-angle glaucoma. Free shipping . [22] The stent is implanted through an ab interno approach and inserted into the supraciliary space (between the ciliary body and sclera), effectively creating a controlled cyclodialysis cleft, which is kept open by the device.[23][24]. Aqueous humor is produced in the portion of the eye known as the ciliary body. Two recent additions to the laser treatment procedures have proven useful even before the glaucoma is far advanced. The XEN Gel Stent is an implantable transcleral microsurgical device that allows the aqueous fluid to drain from the anterior chamber into the subconjunctival space, a pathway utilized by traditional trabeculectomy and glaucoma drainage device surgeries. Previously, laser cyclophotocoagulation was reserved for advanced glaucoma that could not be controlled despite trabeculectomy or tube shunts. Using tiny tubes with very small internal openings, the front of the eye is connected to the suprachoroidal space between the retina and the wall of the eye (Glaukos shunts) to augment the drainage of fluid from the eye. Update on CyPass Micro-Stent: On August 29, 2018, Alcon announced an immediate, voluntary market withdrawal of the CyPass Micro-Stent from the global market and advised surgeons to immediately cease further implantation with the CyPass Micro-Stent. When these two options are no longer sufficient or are not suitable, … [27][28] The CyPass device has been CE-marked since 2009. There are also newer procedures known as minimally invasive glaucoma surgery (MIGS) that hold promise at treating glaucoma. These are endocyclophotocoagulation and micropulse cyclophotocoagulation. They sometimes produced severe inflammation that could reduce vision. These procedures … The stent is made of a non-bioreactive material, which does not promote scarring of the conjunctiva. [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. [1][2] While MIGS procedures offer fewer side effects, the procedures tend to result in less intraocular pressure (IOP) lowering than with trabeculectomy or glaucoma tube shunt implantation. Several operations have been devised using tiny equipment and devices to cut through the trabecular meshwork without damaging any other tissues in the ocular drainage pathway. While all types of glaucoma surgery share the same goal of lowering eye pressure, MIGS has been specifically developed with the goal of reducing the risk of complications associated with traditional glaucoma surgeries. The procedures were designed to reduce the fluid-forming capacity of the eye by targeting the delicate tissue (ciliary body) that makes the fluid. (2018 update: See note below regarding the CyPass Micro-Stent). [15][16], To address the reduced effectiveness at 2 years, some studies have been performed with multiple iStents. Reported adverse reactions include intraocular inflammation, bleeding, and cystoid macular edema (swelling of the retina). During the last 25 years, glaucoma management has been based in the use of pharmaceutical therapies and incisional surgery. The MIGS group of operations have been developed in recent years to reduce some of the complications of most standard glaucoma surgeries. [1], MIGS procedures offer an excellent safety profile, with minimal incidence of complications, especially when compared with other forms of glaucoma surgery.[1][2][6]. While they reduce the incidence of complications, some degree of effectiveness is also traded for the increased safety. [41] A Cochrane Review published in 2019 found no relevant published studies on endoscopic cyclophotocoagulation to assess its effectiveness compared to other surgical treatments (including other MIGS), laser treatment or medical treatment. [40], Endocyclophotocoagulation is indicated for the treatment of both open and closed angle glaucoma and is performed in eyes which have already undergone cataract surgery or performed concomitantly with cataract removal. The goal of all glaucoma surgery is to lower eye pressure to prevent or reduce … These procedures are currently targeted at patients with mild-to-moderate glaucoma. Minimally … The goal of all glaucoma surgery is to lower eye pressure to prevent or reduce damage to the optic nerve. June 23, 2020. MIGS objective, like all glaucoma surgeries, is to achieve lowering of IOP by either increasing aqueous humour outflow, the fluid that is produced by the eye and fills the space between the cornea and the lens, or decreasing the production of aqueous humour.
