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...

Aim: The aim of this study is to introduced the efficacy, longevity and safety of this new ‘T’shaped limbal based sclera flap with fornix based conjunctival flap trabeculectomy leading to better result like controlling intra ocular pressure satisfactory ,and no shallow anterior chamber after the surgery. Method: As it is a clinical research which was done on 26 patients and all the patient went...

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...

PURPOSE To compare trabeculectomy with mitomycin-C (MMC) application before versus after scleral flap dissection in terms of corneal endothelial cell loss and surgical outcomes. METHODS In this double blind clinical trial, patients were randomized to MMC 0.02% application before (group A) or after (group B) scleral flap dissection. The main outcome measure was corneal endothelial cell density...

AIM To determine the long-term efficacy of small flap trabeculectomy (microtrabeculectomy) in terms of intraocular pressure (IOP) control in relatively low risk eyes. METHOD A review of a case series of small flap trabeculectomy procedures performed on 36 eyes from 36 patients with a minimum follow up of 24 months (mean 50.8). RESULTS The mean (SD) intraocular pressures at presentation and ...

TITLE: Analysis of bleb morphology after trabeculectomy with anterior segment optical coherence tomography. PURPOSE: To describe the use of Anterior segment optical coherence tomography (AS OCT ) in imaging of trabeculectomy bleb to find out the morphology and internal structure, and correlate its internal characteristics with the function of the bleb. METHODS: Observational case-series study.6...

PURPOSE To elucidate the potential of three-dimensional anterior segment optical coherence tomography (3D AS-OCT) for identifying filtration openings where aqueous humor flows from the sclera into the subconjunctival space. METHODS We used 3D AS-OCT and custom software to identify filtration openings, which were defined by pits and/or troughs in fluid-filled cavities in both horizontal and ve...

Recently, many discussions occurred concerning non-penetrating filtering surgery. Viscocanalostomy and deep sclerectomy with external trabeculectomy are the most practiced techniques. Their goal is to reduce intraocular pressure by enhancing the natural aqueous outflow, while reducing its resistance. Both techniques involve the removal of a deep scleral flap, the external wall of Schlemm's cana...

Hypotony maculopathy is a sight-threatening complication after trabeculectomy. We report on a 34-year-old man with juvenile open-angle glaucoma and high myopia, who developed hypotony maculopathy 14 years after trabeculectomy without bleb leak. This represents the longest known period from trabeculectomy to the development of hypotony maculopathy without bleb leak. The possible mechanisms for t...
