AIM To evaluate the magnetic properties of the Ex-PRESS stainless steel glaucoma drainage device during MRI. DESIGN Experimental study. METHODS The Ex-PRESS glaucoma drainage device (316L stainless steel) was examined for magnetic field interactions under standard 1.5, 3.0, and 4.7 T MRI scanning protocols. Testing included measurements of translational and rotational motion of the device i...

OBJECTIVE To investigate the phenotype and age-related penetrance of primary open-angle glaucoma (POAG) in Australian families with the myocilin mutation Thr377Met. METHOD AND DESIGN Cross-sectional genetic study. Four unrelated pedigrees carrying the Thr377Met mutation were ascertained from more than 2000 consecutive cases of POAG in the Glaucoma Inheritance Study in Tasmania and from famili...

Glaucoma drainage implants are frequently used in children with severe forms of glaucoma, and tube extenders are sometimes required to compensate for ocular growth or when the intraocular portion of the tube is thought to be too short. We report 2 cases of spontaneous disconnection of a tube extender, occurring 8 months after insertion in one case and 3 years later in the other. In both cases t...

Congenital iris ectropion is a rare condition; non-progressive anomaly characterised by the presence of iris pigment epithelium on the anterior surface of the iris stroma and is frequently associated with anterior iris insertion, dysgenesis of the drainage angle and glaucoma. This paper describes unusual case of bilateral case of congenital iris ectropion in adult patient with pupillary abnorma...

While conventional glaucoma filtration surgery provides excellent intraocular pressure (IOP) lowering effect, this comes at the expense of significant risks. As the physiology of the suprachoroidal space has become better understood, its potential as a source for aqueous drainage has generated significant interest. This has resulted in the creation of several suprachoroidal glaucoma devices wit...

Primary open angle glaucoma (POAG) involves a spectrum of disorders typified by a characteristic optic neuropathy and field loss in eyes with open drainage angles. It is currently a leading cause of blindness worldwide, and in the future should become even more important as populations age throughout the world. Recently, we have witnessed a number of exciting advances in glaucoma. Developments ...
