Cataract prevalence increases with age. As the world's population ages, cataract-induced visual dysfunction and blindness is on the increase. This is a significant global problem. The challenges are to prevent or delay cataract formation, and treat that which does occur. Genetic and environmental factors contribute to cataract formation. However, reducing(More)
OBJECTIVE To establish the absolute risk of contact lens (CL)-related microbial keratitis, the incidence of vision loss and risk factors for disease. DESIGN A prospective, 12-month, population-based surveillance study. PARTICIPANTS New cases of CL-related microbial keratitis presenting in Australia over a 12-month period were identified through(More)
AIM To investigate the aspects of spectacle correction of vision-impairing refractive error and presbyopia in those aged >or=40 years in Timor-Leste. METHOD A population-based cross-sectional survey with cluster random sampling was used to select 50 clusters of 30 people. Those who had uncorrected or undercorrected refractive error (presenting acuity(More)
PURPOSE To characterize refractive error, presbyopia and their correction among adults aged ≥ 40 years in Fiji, and contribute to a regional overview of these conditions. METHODS A population-based cross-sectional survey using multistage cluster random sampling. Presenting distance and near vision were measured and dilated slitlamp examination performed.(More)
BACKGROUND A rapid assessment methodology was used to determine the suitability of donated recycled spectacles for the Pacific nation of Tuvalu. METHODS Spectacles (102) from a donated cache were examined. Those with astigmatism of > 1.00 D, anisometropia of > 0.50 D, significant central lens scratches, broken frame, poor cosmetic fit and comfort, or(More)
AIM To estimate the prevalence and causes of blindness and low vision in people aged > or = 40 years in Timor-Leste. METHOD A population-based cross-sectional survey using multistage cluster random sampling to identify 50 clusters of 30 people. A cause of vision loss was determined for each eye presenting with visual acuity worse than 6/18. RESULTS Of(More)
PURPOSE To characterize refractive error, presbyopia, and spectacle correction among adults aged ≥40 years in Timor-Leste in 2010 and examine the impact of the National Spectacle Program by comparing results to those obtained 5 years earlier. METHODS A population-based, cross-sectional survey sampled 50 clusters of 45 people each. Participants with(More)
PURPOSE To evaluate surveillance methods in a pilot epidemiological study of contact lens related microbial keratitis (MK) cases identified by ophthalmic practitioners in Australia and New Zealand between May and August 2003 inclusive. METHODS Twelve ophthalmologists and 55 optometrists from rural and metropolitan locations were sent a study information(More)
OBJECTIVE To establish risk factors for moderate and severe microbial keratitis among daily contact lens (CL) wearers in Australia. DESIGN A prospective, 12-month, population-based, case-control study. PARTICIPANTS New cases of moderate and severe microbial keratitis in daily wear CL users presenting in Australia over a 12-month period were identified(More)
PURPOSE To evaluate a multi-source surveillance system used in a 12-month study of contact lens related microbial keratitis in Australia and New Zealand. METHODS All practicing ophthalmologists and optometrists were surveyed on 6 occasions over 12 months via post or the Internet. Participation was defined as reporting at least once during the study period(More)
