Deep sclerectomy (DS) is a non-penetrating glaucoma surgery that has emerged as a competitor to the standard trabeculectomy which is safer with comparable results regarding intraocular pressure (IOP)-lowering effect in cases with open-angle glaucoma (OAG). DS entails non-penetration of the anterior chamber through leaving an intact trabeculo-Descemetic membrane (TDM) that acts as barrier to prevent marked postoperative hypotony that follows trabeculectomy [The presence of intra-scleral lake is a unique feature of DS, and its dimensions can be correlated with postoperative IOP in cases with OAG [Sutureless deep sclerectomy (SDS) is a relatively recent modification to DS that converts the conventional surgery to be completely sutureless with no sutures at the scleral flap or the conjunctival edges. This technique is supposed to decrease complications like foreign body reaction, excessive tissue trauma, and local irritation due to the use of sutures. It has shorter operation time, there is no need for postoperative suture removal, and it is more economic than the conventional one [The aim of this study is to compare sutureless deep sclerectomy to conventional deep sclerectomy regarding their lowering effect on IOP in cases with open-angle glaucoma.
