Abstract

This study assessed the prevalence of cataract blindness, cataract surgical coverage (CSC), effective CSC, visual outcome after cataract surgery, and barriers to cataract surgery in a population aged 50 years and older in Armenia using Rapid Assessment of Avoidable Blindness (RAAB) methodology. The study sample included 2258 individuals aged 50 years and older who were randomly selected from 11 provinces of Armenia in 2019 following the RAAB methodology. The study team randomly selected 50 clusters, 50 people in each. The RAAB survey form was used to collect information on cataract blindness, visual outcome after cataract surgery, and barriers to cataract surgery. The mean age of the participants was 65.3 (SD = 9.9) ranging from 50 to 99. The majority of participants were women (65.6%). Age- and sex-adjusted prevalence of blindness due to all causes was 1.5%; of which 36.4% was bilaterally blind due to cataract. The CSC and effective CSC at a cataract surgical threshold of <6/12 were 55.1% and 24.4%, respectively. Good outcome was reported in 43.7% of eyes after cataract surgery, borderline in 37.2% of eyes, and poor outcome in 19.1%. The main barriers to cataract surgery included "cost," "need not felt," or "fear." The prevalence of cataract blindness in our study was higher compared to high-income regions and lower than estimates from South/Southeast Asia. This study suggests the urgent need to update the National Strategic Plan to prevent blindness in Armenia with a focus on improving the quality and coverage of cataract surgery.

Abstract

This study aimed to estimate the prevalence and main causes of blindness and visual impairment in population aged 50 years and older in Armenia using Rapid Assessment of Avoidable Blindness (RAAB) methodology. The study team randomly selected 50 clusters (each consisting of 50 people) from all 11 regions of Armenia. Data on participants' demographics, presenting visual acuity, pinhole visual acuity, principal cause of presenting visual acuity, spectacle coverage, uncorrected refractive error (URE), and presbyopia were collected using the RAAB survey form. Four teams of trained eye care professionals completed data collection in 2019. Overall, 2,258 people of 50 years and older participated in the study. The age- and gender- adjusted prevalence of bilateral blindness, severe and moderate visual impairment were 1.5% (95% CI: 1.0–2.1), 1.6% (95% CI: 1.0–2.2) and 6.6% (95% CI: 5.5–7.7), respectively. The main causes of blindness were cataract (43.9%) and glaucoma (17.1%). About 54.6% and 35.3% of participants had URE and uncorrected presbyopia, respectively. The prevalence of bilateral blindness and functional low vision increased with age and was the highest in participants 80 years and older. The rate of bilateral blindness was comparable with findings from countries that share similar background and confirmed that untreated cataract was the main cause of blindness. Given that cataract blindness is avoidable, strategies should be developed aiming to further increase the volume and quality of cataract care in Armenia. [ABSTRACT FROM AUTHOR]

Abstract

AIM: To review existing data for the prevalence of corrected, uncorrected, and inadequately corrected refractive errors and spectacle wear in Hungary. METHODS: Data from two nationwide cross-sectional studies were analysed. The Rapid Assessment of Avoidable Blindness study collected population-based representative national data on the prevalence of visual impairment due to uncorrected refractive errors and spectacle coverage in 3523 people aged ≥50y (Group I). The Comprehensive Health Test Program of Hungary provided data on the use of spectacles in 80 290 people aged ≥18y (Group II). RESULTS: In Group I, almost half of the survey population showed refractive errors for distant vision, about 10% of which were uncorrected (3.2% of all male participants and 5.0% of females). The distance spectacle coverage was 90.7% (91.9% in males; 90.2% in females). The proportion of inadequate distance spectacles was found to be 33.1%. Uncorrected presbyopia was found in 15.7% of participants. In all age groups (Group II), 65.4% of females and 56.0% of males used distance spectacles, and approximately 28.9% of these spectacles were found to be inappropriate for dioptric power (with 0.5 dioptres or more). The prevalence of inaccurate distance spectacles was significantly higher in older age groups (71y and above) in both sexes. CONCLUSION: According to this population-based data, uncorrected refractive errors are not rare in Hungary. Despite recent national initiatives, further steps are required to reduce uncorrected refractive errors and associated negative effects on vision, such as avoidable visual impairment.

Abstract

AIM: To examine the prevalence and composition of refractive errors in Hungary. METHODS: Nationwide cross-sectional data collected between 2014 and 2019 were analysed from the Comprehensive Health Screening Program of Hungary, which provided spectacle dioptric power and autorefractometry data for 68 227 people (35 850 women and 32 377 men). Their age distribution, 18-99y, was similar to the national demographic distributions. RESULTS: Of the total population, 16.50% of the refractive errors exhibited hyperopia, 40.05% emmetropia, and 43.45% myopia. Myopia was 3 times more frequent (58.7%) in younger ages (18-35y of age) compared to older age groups (19.4% of those 56-70y of age; P

Abstract

BackgroundThis study aimed to assess the prevalence and causes of vision loss in sub-Saharan Africa (SSA) in 2015, compared with prior years, and to estimate expected values for 2020.MethodsA systematic review and meta-analysis assessed the prevalence of blindness (presenting distance visual acuity In SSA, age-standardised prevalence of blindness, MSVI and MVI in 2015 were 1.03% (80% uncertainty interval (UI) 0.39–1.81), 3.64% (80% UI 1.71–5.94) and 2.94% (80% UI 1.05–5.34), respectively, for male and 1.08% (80% UI 0.40–1.93), 3.84% (80% UI 1.72–6.37) and 3.06% (80% UI 1.07–5.61) for females, constituting a significant decrease since 2010 for both genders. There were an estimated 4.28 million blind individuals and 17.36 million individuals with MSVI; 101.08 million individuals were estimated to have near vision loss due to presbyopia. Cataract was the most common cause of blindness (40.1%), whereas undercorrected refractive error (URE) (48.5%) was the most common cause of MSVI. Sub-Saharan West Africa had the highest proportion of blindness compared with the other SSA subregions.ConclusionsCataract and URE, two of the major causes of blindness and vision impairment, are reversible with treatment and thus promising targets to alleviate vision impairment in SSA.

Abstract

OBJECTIVE: To test the applicability of lot quality assurance sampling (LQAS) for the rapid assessment of the prevalence of active trachoma. METHODS: Prevalence of active trachoma in six communities was found by examining all children aged 2-5 years. Trial surveys were conducted in these communities. A sampling plan appropriate for classifying communities with prevalences 40% was applied to the survey data. Operating characteristic and average sample number curves were plotted, and screening test indices were calculated. The ability of LQAS to provide a three-class classification system was investigated. FINDINGS: Ninety-six trial surveys were conducted. All communities with prevalences 40% were identified correctly. The method discriminated between communities with prevalences 30%, with sensitivity of 98% (95% confidence interval (CI) = 88.2-99.9%), specificity of 84.4% (CI = 69.9-93.0%), positive predictive value of 87.7% (CI = 75.7-94.5%), negative predictive value of 97.4% (CI = 84.9-99.9%), and accuracy of 91.7% (CI = 83.8-96.1%). Agreement between the three prevalence classes and survey classifications was 84.4% (CI = 75.2-90.7%). The time needed to complete the surveys was consistent with the need to complete a survey in one day. CONCLUSION: Lot quality assurance sampling provides a method of classifying communities according to the prevalence of active trachoma. It merits serious consideration as a replacement for the assessment of the prevalence of active trachoma with the currently used trachoma rapid assessment method. It may be extended to provide a multi-class classification method.

Abstract

Background: Eye conditions in children can have negative consequences on visual functioning and quality of life. There is a lack of data on the magnitude of children with eye conditions who need services for effective planning of school eye health programmes. To address this, the School Eye Health Rapid Assessment (SEHRA) tool is being developed to collect data to support school eye health programme planning.Methods: The module, 'the magnitude and nature of local needs in school children' is the first of six modules in the SEHRA tool. The module outlines a school-based cluster survey designed to determine the magnitude of eye health needs in children. This paper outlines the survey sampling strategy, and sample size calculations.Results: The requirements for the SEHRA survey indicate that in regions where a larger sample size is required, or where fewer schools are recruited to the survey, confidence in the accuracy of the data will be lower.Conclusions: The SEHRA survey module 'the magnitude and nature of local needs in school children' can be applied in any context. In certain circumstances, the confidence in the survey data will be reduced. [ABSTRACT FROM AUTHOR]

Methods The LQAS survey method for the rapid assessment of the prevalence of active trachoma was adapted for use in Viet Nam with the aim of classifying individual communes by the prevalence of active trachoma among children in primary school. School-based sampling was used; school sites to be sampled were selected using an area-sampling approach. A total of 719 communes in 41 districts in 18 provinces were surveyed. Findings Survey staff found the LQAS survey method both simple and rapid to use after initial problems with area-sampling methods were identified and remedied. The method yielded a finer spatial resolution of prevalence than had been previously achieved in Viet Nam using semiquantitative rapid assessment surveys and multistage cluster-sampled surveys. Conclusion When used with area-sampling techniques, the LQAS survey method has the potential to form the basis of survey instruments that can be used to efficiently target resources for interventions against active trachoma. With additional work, such methods could provide a generally applicable tool for effective programme planning and for the certification of the elimination of trachoma as a blinding disease.
