Research Article: Sulcus Tube Internal Needle Guidewire Technique for Glaucoma Drainage Device Placement: Improving Surgical Ease and Precision
Abstract:
Despite the rise of micro-invasive glaucoma surgery (MIGS), glaucoma drainage device implantation continues to be a mainstay among glaucoma surgical treatment options. Anterior chamber tube placement, while effective in reducing intraocular pressure (IOP), poses corneal endothelial risks. Ciliary sulcus tube placement shows promise in reduced corneal endothelial cell loss, but proper sulcus placement can be challenging. Our study describes the initial safety and effectiveness results using a novel sulcus tube internal needle guidewire (STING) technique for glaucoma drainage device insertion into the ciliary sulcus.
Introduction:
Despite the advent of MIGS, glaucoma drainage device placement for the treatment of glaucoma remains a mainstay of surgical glaucoma management particularly for refractory glaucoma. Many glaucoma drainage devices are available, and various techniques for tube placement have been described. These include placement of the tube into the anterior chamber (AC), ciliary sulcus (CS), or anterior vitreous cavity via the pars plana.
