Aim: To analyze the features of the filtering blebs following implantation of the Ex-PRESS glaucoma device (model P-50) with the aid of the Visante anterior segment optical coherence tomography (AS-OCT).
Methods: Five patients with open angle glaucomas were included in the study. They all underwent implantation of the Ex-PRESS device under a scleral flap. The surgical procedure was augmented with the use of mitomycin C subconjunctivally. The filtering blebs were analyzed with the Visante AS-OCT with the scans taken along the axis of the implantation of the glaucoma device.
Results: All filtering blebs were graded as diffuse functioning. The morphological characteristics of the blebs were similar to those of the trabeculectomy. However the use of the Ex-PRESS implant tend to form a characteristic episcleral lake at the site of the plate of the implant.
Conclusion: The use of the Ex-PRESS implant produces filtering blebs similar to those of the trabeculectomy with the formation of a characteristic episcleral lake at the site of the plate of the implant.

Sonographic bleb visualisation after PAUL glaucoma implant surgery.
Br J Ophthalmol

Department of Ophthalmology, University of Bonn, Bonn, Germany.
Background/aims: Bleb characteristics in the area around the plate following glaucoma drainage device (GDD) surgery are difficult to evaluate on slit lamp examination. Ultrasound sonography could be used for more detailed visualisation. The aim of this study was to describe bleb configuration after PAUL glaucoma implant (PGI) surgery and evaluate the possible correlation with intraocular pressure (IOP) in order to derive new markers for evaluating GDD function.

Introduction: Intrableb structures are hallmark features of the filtering bleb. This study aimed to compare the characteristics of functioning blebs using anterior segment optical coherence tomography (AS-OCT) according to amniotic membrane transplantation (AMT).
Methods: Forty eyes from 40 patients diagnosed with primary open-angle glaucoma who underwent trabeculectomy, either with AMT (20 eyes) or without AMT (control group, 20 eyes), were included.
