BACKGROUND/OBJECTIVE Parkinson's disease (PD) and the atypical parkinsonian syndromes multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS) are movement disorders associated with degeneration of the central nervous system. Degeneration of the retina has not been systematically compared in these diseases. (More)
Antiglaucomatous implant surgery is a continously evolving field in glaucoma treatment. A literature search with the terms “glaucoma implant surgery”, “aqueous shunts” and “glaucoma drainage devices” was carried out, especially giving prominence to innovative surgical developments in glaucoma implant surgery and to recently established clinical evidence on(More)
BACKGROUND Optical coherence tomography can be used to assess retinal degeneration in multiple sclerosis (MS). Thinning of the retinal nerve fibre layer and macular thickness have been well characterized, but newer devices allow quantification of all retinal layers. OBJECTIVES The objective of this study was to evaluate the thickness of the paramacular(More)
PURPOSE To assess the intraocular pressure-lowering efficacy and the postoperative complication profile of viscocanalostomy versus trabeculectomy. PATIENTS AND METHODS Sixty eyes of 60 patients with medically uncontrolled open-angle glaucoma were randomized either to the viscocanalostomy or to the trabeculectomy group of the trial. Viscocanalostomy was(More)
OBJECTIVE To evaluate implantation of a zonal-progressive multifocal intraocular lens (IOL) in children. STUDY DESIGN Prospective, noncomparative, interventional case series. PARTICIPANTS Thirty-five eyes of 26 pediatric patients aged 2 to 14 years with multifocal IOL implantation at one institution with more than 1 year of follow-up. INTERVENTIONS(More)
INTRODUCTION The aim of this study was to differentiate the pressure-reducing results following trabecular aspiration combined with small incision cataract surgery in eyes with pseudoexfoliation depending on preoperative pressure and medication score. PATIENTS AND METHODS A retrospective analysis was made of 104 exfoliative eyes of 104 patients who(More)
BACKGROUND Dye solutions for intraoperative staining of epiretinal membranes and the internal limiting membrane improve the visualisation of these thin structures and facilitate their removal. In the present study the authors investigated the effects of indocyanine green 0.05%, trypan blue 0.15%, and patent blue 0.48% on bovine retinal function. METHODS(More)
OBJECTIVE The primary cause of intraocular pressure (IOP) elevation in pseudoexfoliation glaucoma is obstruction of the intertrabecular spaces by exfoliation material. Previously, the authors reported on a new concept of nonfiltering glaucoma surgery-trabecular aspiration-designed to increase trabecular outflow in pseudoexfoliation glaucoma. In the current(More)
PURPOSE In glaucoma surgery, scarring of the artificial fistula is the limiting factor for long-term control of intraocular pressure (IOP). Several devices and surgical techniques have been developed for artificial aqueous humor drainage in intractable glaucoma. The authors describe a novel surgical technique that uses a silicone tube as a shunt for aqueous(More)
PURPOSE To study prospectively the safety and pressure-reducing efficacy of the Y-shaped Eyepass glaucoma implant (GMP Vision Solutions, Inc.). SETTING Departments of Ophthalmology, University of Cologne, Cologne, and University of Erlangen, Erlangen, Germany. METHODS This study comprised 12 patients with primary open-angle or exfoliative glaucoma and(More)
