BackgroundCataract is the leading cause of blindness globally. Effective cataract surgical coverage (eCSC) measures number people in a population who have been operated on for cataract, and had good outcome, as proportion all or requiring surgery. Therefore, eCSC describes service access (ie, coverage, [CSC]) adjusted quality. The 74th World Health Assembly endorsed global target 30-percentage point increase by 2030. To enable monitoring progress towards this target, we analysed Rapid...
We undertook a Grand Challenges in Global Eye Health prioritisation exercise to identify the key issues that must be addressed improve eye health context of an ageing population, eliminate persistent inequities health-care access, and mitigate widespread resource limitations.Drawing on methods used previous studies, we multi-step recruitment strategy assemble diverse panel individuals from range disciplines relevant global all regions globally participate three-round, online, Delphi-like,...
BackgroundIn 2021, WHO Member States endorsed a global target of 40-percentage-point increase in effective refractive error coverage (eREC; with 6/12 visual acuity threshold) by 2030. This study models and regional estimates eREC as baseline for the initiative.MethodsThe Vision Loss Expert Group analysed data from 565 448 participants 169 population-based eye surveys conducted since 2000 to calculate (met need/[met need + undermet unmet need]). A binary logistic regression model was used...
the neural mechanisms of distension-induced esophagoupper esophageal sphincter (UES) reflexes have not been explored in humans. We investigated modulation these by mucosal anesthesia, acid exposure, and GABA(B) receptor activation. In 55 healthy human subjects, UES responses to rapid air insufflation slow balloon distension were examined before after pretreatment with 15 ml topical lidocaine, HCl infusion, baclofen 40 mg given orally. response distension, can variably relax or contract....
Purpose: We sought to determine the prevalence of trachomatous inflammation – follicular (TF) in children aged 1–9 years, and trichiasis (TT) those ≥15 suspected trachoma-endemic areas Papua New Guinea (PNG).Methods: carried out six population-based surveys using protocol developed as part Global Trachoma Mapping Project.Results: A total 19,013 individuals were sampled for inclusion, with 15,641 (82.3%) consenting participate. Four evaluation units had prevalences TF ≥10%, above which...
Objective To estimate the prevalence and main causes of blindness vision impairment in people aged 50 years older Papua New Guinea (PNG). Design National cross-sectional population-based survey Capital District (NCD), Highlands, Coastal Islands regions. Methods Adults above were recruited from 100 randomly selected clusters. Each participant underwent monocular presenting pinhole visual acuity (VA) assessment lens examination. Those with VA<6/12 either eye had a dilated fundus examination...
There are 161 million people living with vision impairment, due to uncorrected refractive errors. A further 510 near-vision impairment. is a need for clearly defined indicators that capture the quality of error service outputs and outcomes provide insights shape, change stimulate action. This study aims evaluate care (Q.REC) in Cambodia, Malaysia Pakistan, by using unannounced standardised patients (USPs) identify proportion prescribed dispensed spectacles appropriate people's needs...
Quality refractive error care is essential for reducing vision impairment. indicators and standardized approaches assessing the quality of need to be established.This study aimed develop a set test their applicability in real-world setting using unannounced patients (USPs).Patient outcomes three (Q.REC) (1, optimally prescribed spectacles; 2, adequately 3, vector dioptric distance) were developed existing literature, refraction training standards, consulting educators. Twenty-one USPs with...
Purpose Quality-of-care in refractive error services is essential, as it directly affects vision outcomes, wellbeing, educational attainment, and workforce participation. In Cambodia, uncorrected a leading cause of mild moderate impairment adults. We evaluated the quality care Cambodia by estimating proportion prescribed dispensed spectacles appropriate for people's needs factors associated with spectacle quality.
Background/aims To conduct an assessment of avoidable blindness, diabetes mellitus and diabetic retinopathy (DR) in adults aged 50 years older the National Capital District (NCD) region Papua New Guinea (PNG). Methods A cross-sectional population-based survey was performed for which 25 clusters people ≥50 were randomly selected from NCD region. The standardised rapid blindness (RAAB) with (+DR) methodology used. Blindness defined as presenting visual acuity <3/60 better eye. Participants...
Vision impairment among children is associated with lower levels of educational attainment. School-based eye health programs have the potential to provide high-quality and cost-effective services that assist in prevention blindness uncorrected vision impairment, particularly low-resources settings. The aim this study was identify key factors inhibit or facilitate provision school-based programs, including referral care services, for Malawian Central Region. In-depth interviews (n = 10) focus...
The aim of this study was to develop and validate a new vision-specific quality life (VS QoL) instrument assess the impact vision impairment eye disease on adults in Papua New Guinea (PNG).This designed as community based cross-sectional.Six hundred fourteen aged 18 above were included study.Focus groups interviews guided development 41-item instrument. Two valid subscales obtained using pilot data after an iterative item reduction process by Rasch-based parameters. person measures (in...
Purpose: To determine how people attending outreach eye care clinics in Papua New Guinea (PNG) perceive health and services.Methods: An interview-based questionnaire was administrated to a convenience sample of 614 adult participants across four provinces perceptions services were recorded. Presenting near visual acuity measured cause impairment (VI) determined.Results: In this sample, 113/614 (18.4%) presented with distance VI, 16 (2.6%) blindness, 221 (47.6%) VI. Older those VI more likely...
Background: Routine eye and vision assessments are vital for the detection subsequent management of loss, which is particularly important Aboriginal Torres Strait Islander people, who face higher rates loss than other Australians. In order to guide improvements, this paper will describe patterns, variations gaps in these people. Methods: Clinical audits from 124 primary health care centres (sample size 15,175) five Australian States Territories were conducted during 2005-2012. Main outcome...
To determine willingness to pay for children's spectacles, and barriers purchasing spectacles in Cambodia.We conducted vision screenings, eye examinations as indicated, all consenting children at 21 randomly selected secondary schools. We invited parents/guardians of found have refractive problems complete a survey, using binary-with-follow-up technique.We screenings on 12 128 schoolchildren, surveys with 491 (n=491) from Kandal Phnom Penh provinces Cambodia. 519 error, 7 who had...
