PURPOSE To describe a pilot study that evaluates the efficacy and mechanism of action of a new glaucoma operation, trabeculectomy with internal tube shunt. METHODS Twenty-three patients underwent the new operation in one eye for open angle glaucoma. Under a scleral flap, a deep sclerectomy was performed, resulting in an intrascleral lake. Laterally, on both sides, a small silicone tube was pl...

PURPOSE A simple needling procedure is the standard method for restoring the function of an encapsulated bleb after trabeculectomy. However, postoperative hypotony represents a possible hazard. This study describes a new surgical approach for treating encapsulated blebs with reduced risk of early postoperative hypotony: bleb needling combined with transconjunctival sutures tightening the sclera...

PURPOSE Trabeculectomy surgery is the most common operative procedure for the treatment of medically uncontrolled glaucoma. Variability exists in both the design and the position of the limbal wound as well as in outcomes, even in cases with similarly designed wounds. The purpose of this study is to describe the histologic features of the surgical site of human eyes received at a pathology labo...

Trabeculectomy remains the standard surgery for intraocular pressure control for glaucoma. It involves a full thickness penetration of sclera, to allow aqueous seepage to subconjunctival space under a scleral flap. However, it carries the risk of serious bleb related complications like overfiltration, hypotony and consequent persistent choroidal detachment, shallow anterior chamber, cataract, p...
