PURPOSE To study the clinical effectiveness of viscocanalostomy in a population of black African patients with open-angle glaucoma that was uncontrolled on medical treatment. SETTING Department of Ophthalmology, Medical University of Southern Africa, Medunsa, South Africa. METHODS In this prospective study viscocanalostomy was performed in 214 eyes of(More)
PURPOSE To assess the aqueous outflow pathway in primary open-angle glaucoma (POAG) through provocative gonioscopy and channelography with a flexible microcatheter and fluorescein tracer during canaloplasty. METHODS One eye each was randomly selected from 28 consecutive black African POAG patients undergoing canaloplasty. Provocative gonioscopy was(More)
BACKGROUND/AIMS To study the safety and effectiveness of 360° viscodilation and tensioning of Schlemm canal (canaloplasty) in black African patients with primary open-angle glaucoma (POAG). METHODS Sixty randomly selected eyes of 60 consecutive patients with POAG were included in this prospective study. Canaloplasty comprised 360° catheterisation of(More)
PURPOSE To present a modified surgical technique for preventing posterior capsule opacification (PCO) in children with congenital cataracts and to evaluate its long-term efficacy. SETTING Department of Ophthalmology, Medical University of Southern Africa, Medunsa, South Africa. METHODS Anterior and posterior vertical capsulotomy, with optic entrapment(More)
BACKGROUND The aim of this study is to present a new approach to visualize the aqueous outflow system during glaucoma surgery using a flexible microcatheter and fluorescein, called channelography. PATIENTS AND METHODS Schlemm's canal was unroofed in a standard non-penetrating dissection technique in patients undergoing canaloplasty. A flexible(More)
This prospective study was undertaken to evaluate the role of duplex Doppler (DD) scanning in the diagnosis of masses of suspected vascular origin at the carotid bifurcation. We also assessed the different DD signs of carotid body tumors, especially the difference in resistance index (RI) in the external carotid artery on the side of the tumor. Over a(More)
Adnexal torsion is an uncommon cause of severe lower abdominal pain in women and is often difficult to distinguish from other acute abdominal conditions. However, adnexal torsion should be considered in premenarcheal girls admitted with acute abdominal pain and evidence of an ovarian mass. Accurate and early radiological diagnosis is mandatory immediately(More)
PurposeTo compare the safety and efficacy of two polypropylene (Prolene) sutures for tensioning of the inner wall of Schlemm's canal (SC) in black African patients with primary open-angle glaucoma (POAG) undergoing canaloplasty.MethodsIn a prospective randomised trial of 90 patients, canaloplasty was performed with a flexible microcatheter (iTrack-250A) and(More)
PURPOSE To study the safety and long-term efficacy of classic viscocanalostomy in patients with open-angle glaucoma (OAG) in different populations. METHODS A total of 726 eyes of 726 patients from Europe or South Africa with primary OAG (POAG) and pseudoexfoliative glaucoma (PXFG) were included in this retrospective multicentre study.
