Cataract is the leading cause of blindness in South Africa, responsible for about 50% of the prevalence of blindness and identified as a national health priority. The cataract surgery rate (CSR) should be at least 2 000 per million population per year for elimination of cataract blindness. The national CSR target was planned to increase from 1 000 in 2005(More)

OBJECTIVE To report on conservation of eyes with choroidal melanoma with a multimodality approach to treatment. DESIGN Prospective, noncomparative, interventional case series. PARTICIPANTS All 1632 patients with choroidal melanoma treated at a single center between 1993 and 2002. INTERVENTION Primary enucleation (35%), brachytherapy (31.3%), proton(More)
PURPOSE Brachytherapy is one method of irradiating the orbit after enucleation of an eye with a malignant tumor that has a potential to recur. It consists of 6 trains of I-125 seeds placed around the periphery of the orbit, a shorter central train, and a metal disc, loaded with seeds, placed beneath the eyelids. The presence of a prosthetic orbital implant(More)
PURPOSE Children with retinoblastoma that extends into or through the choroid, sclera, or optic nerve are at risk of developing orbital disease, as well as metastases. Previously, these enucleated orbits were treated with external beam radiotherapy in addition to chemotherapy. 125I brachytherapy for tumors in and around the eye was pioneered by Sealy in(More)
OBJECTIVE To assess the value of routine polymerase chain reaction (PCR) analysis on intraocular fluid from patients presenting with a first episode of suspected active infectious posterior uveitis in a population with a high prevalence of human immunodeficiency virus infection. DESIGN Retrospective, interventional case series. Participants. 159(More)
AIM To evaluate the diagnostic accuracy of methylene blue used as a non-invasive in vivo stain to detect ocular surface squamous neoplasia (OSSN). METHODS A test validation study was performed according to Standards for the reporting of diagnostic accuracy studies (STARD) guidelines on 75 consecutive patients who presented with ocular surface lesions(More)
PURPOSE To estimate the prevalence and causes of blindness and visual impairment in Cape Town, South Africa and to explore socio-economic and demographic predictors of vision loss in this setting. METHODS A cross sectional population-based survey was conducted in Cape Town. Eighty-two clusters were selected using probability proportionate to size(More)
Schneiderian papillomas are benign tumours, with an aggressive nature. A case with a recurrent Schneiderian papilloma of the nasolacrimal sac, who underwent an external dacryocystorhinostomy (DCR) with irrigation of the nasolacrimal system with 0.02% mitomycin C (MMC), is presented at 18 months follow-up. External DCR using MMC, as an adjuvant therapy, is a(More)
