Hirabayashi MT, et al. - In eyes with open-angle glaucoma (OAG) undergoing phacoemulsification cataract surgery, researchers compared decreases in intraocular pressure (IOP) and IOP-lowering medication use following sectoral excisional goniotomy with the Kahook Dual Blade (KDB) or 360° trabeculotomy (via either Trab360 or gonioscopy-assisted transluminal trabeculotomy [GATT]). For this retrospective review, they obtained data from 74 eyes of 61 patients undergoing KDB excisional goniotomy and 27 eyes of 25 patients undergoing 360° trabeculotomy. During the first 6 postoperative months, KDB and Trab360 or GATT procedures similarly reduced both IOP and the need for IOP-lowering medications. At 6 months, more eyes undergoing KDB excisional goniotomy than 360° trabeculotomy exceeded target IOP ≤ 18 mmHg and ≤ 15 mmHg. From this class of micro-invasive glaucoma procedures, a full 360° trabecular bypass may not be necessary to achieve maximal efficacy.
