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)
The keratometry and axial length readings of healthy eyes (405 subjects) and cataractous eyes (63 subjects) from a sample of Tigrinians living in the Eritrean capital of Asmara were obtained. All subjects were at least 40 years of age. The mean keratometry reading for healthy eyes was 43.37 diopters (SD +/- 1.61), while that for cataractous eyes was 43.57(More)
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)
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)
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 The benefits of sutureless cataract surgery have not been available to the majority of developing world patients. This report describes a surgical technique developed to gain the benefits of self-sealing sutureless techniques, without the need for costly, complex instrumentation, expensive consumables, or difficult nucleus fragmentation manoeuvres(More)
BACKGROUND   To estimate the prevalence and causes of blindness and low vision among adults aged ≥40 years in Fiji. DESIGN   Population-based cross-sectional study. PARTICIPANTS   Adults aged ≥40 years in Viti Levu, Fiji. METHOD   A population-based cross-sectional survey used multistage cluster random sampling to identify 34 clusters of 40 people. A(More)
BACKGROUND To characterize diabetic eye disease and its management among adults aged ≥40 years with self-reported diabetes in Fiji. METHODS During a population-based cross-sectional survey using multistage cluster random sampling, participants reported health information, including whether a doctor had diagnosed diabetes. HbA1c and visual acuity were(More)
AIM To estimate the prevalence of diabetes among adults aged ≥40 years in Fiji, and determine the demographic characteristics associated with this diagnosis. METHOD During a population-based survey, participant glycosylated haemoglobin (HbA1c) was determined and physician diagnosis of diabetes self-reported. HbA1c ≥6.5% or claimed previous diagnosis,(More)
The contribution of the mid-level cadre of eye care providers is an essential component of the Vision 2020: The Right To Sight initiative, to eliminate avoidable blindness by 2020. However, for the past 20 years the functions of this cadre have not been definitively outlined, or universally accepted. Consequently, the competencies they require to provide(More)
