Intraluminal stenting versus external ligation of Ahmed glaucoma valve in prevention of postoperative hypotony.

Aim: To compare intraluminal stenting and external ligation of Ahmed glaucoma valves (AGV) for refractory glaucoma management and postoperative hypotony prevention.

Methods: This randomized prospective blind study included 30 eyes of 25 patients (age range: 44-56y) with refractory glaucoma. This study was conducted from September 2018 to January 2020.

Trabeculectomy with Ologen implant versus perfluoropropane gas bubble for open angle glaucoma in pseudophakic eyes.

Aim: To evaluate the safety and efficacy of augmented trabeculotomy with Ologen versus perfluoropropane in management of pseudophakic glaucoma.

Methods: This is a comparative randomized study included 57 pseudophakic eyes of 57 patients with medically uncontrolled open angle glaucoma (OAG). Twenty-nine patients were allocated in group I (trabeculectomy with Ologen; trab-ologen group), while 28 patients were assigned in group II (trabeculectomy with perfluoropropane gas bubble; trab-C3F8 gas bubble group).

An Ex-Press implant versus trabeculectomy in a fibrotic bleb with late failure after previous trabeculectomy.

Aim: To compare the outcome of an Ex-Press implant and subscleral trabeculectomy (SST) in the management of glaucoma after previous trabeculectomy on a fibrotic bleb.

Methods: This randomized prospective study included 28 eyes from 28 patients (age range: 42-55y) with primary open angle glaucoma (POAG) presented with elevated intraocular pressure (IOP) with fibrotic bleb despite previous SST for more than 4mo. The eyes enrolled in the study were divided into two groups: group I (subjected to Ex-Press implant surgery) and group II [subjected to SST with mitomycin C (MMC)].

Evaluation of Conjunctival Autografting Augmented with Mitomycin C Application Ologen Implantation in the Surgical Treatment of Recurrent Pterygium.

Objectives: To evaluate the safety and efficacy of augmenting conjunctival autografting with intraoperative mitomycin C (MMC) application Ologen implantation in the management of recurrent pterygium.

Materials And Methods: This prospective randomised study included 63 eyes of 63 patients, with recurrent nasal pterygium, who presented to the outpatient clinic of Menoufia University Hospital in Shebin El Kom and Manshiet Soltan from January 2016 to December 2019. Patients were randomly enrolled into two groups.

Bleb Morphology Using Anterior-Segment Optical Coherence Tomography after Ahmed Glaucoma Valve Surgery with Tenon Capsule Resection.

Objectives: To evaluate the internal morphology of blebs using anterior-segment optical coherence tomography (AS-OCT) and the surgical outcomes of Ahmed glaucoma valve (AGV) surgery with Tenon capsule resection compared to conventional AGV surgery in patients with refractory glaucoma. . This randomised prospective study included 30 eyes from 30 patients (age range: 42-55 y) with refractory glaucoma from March 2018 to February 2020.
