Cross-sectional study of prevalence and correlates of fear of falling in the older people in residential care in India: the Hyderabad Ocular Morbidity in Elderly Study (HOMES).

OBJECTIVE: To report the prevalence and risk factors for the fear of falling (FOF) among older individuals living in residential care facilities in India. DESIGN: Cross-sectional study. SETTING: Homes for the aged centres in Hyderabad, India. PARTICIPANTS: The study included individuals aged ≥60 years from homes for the aged centres. The participants underwent a comprehensive eye examination in make-shift clinics setup in homes. Trained investigators collected the personal and demographic information of the participants and administered the Patient Health Questionnaire-9 and Hearing Handicap Inventory for Elderly questionnaire in the vernacular language. FOF was assessed using the Short Falls Efficacy Scale. The presence of hearing and visual impairment in the same individual was considered dual sensory impairment (DSI). A multiple logistic regression analysis was done to assess the factors associated with FOF. PRIMARY OUTCOME MEASURE: FOF. RESULTS: In total, 867 participants were included from 41 homes for the aged centres in the analyses. The mean (±SD) age of the participants was 74.2 (±8.3) years (range 60-96 years). The prevalence of FOF was 56.1% (95% CI 52.7% to 59.4%; n=486). The multivariate analysis showed that those with DSI had eleven times higher odds of reporting FOF than those with no impairment (OR 11.14; 95% CI 3.15 to 41.4.) Similarly, those with moderate depression had seven times higher odds (OR 6.85; 95% CI 3.70 to 12.70), and those with severe depression had eight times higher odds (OR 8.13; 95% CI 3.50 to 18.90) of reporting FOF. A history of falls in the last year was also associated with increased odds for FOF (OR 1.52; 95% CI 1.03 to 2.26). CONCLUSION: FOF is common among older individuals in residential care in India. Depression, falling in the previous year and DSI were strongly associated with FOF. A cross-disciplinary approach may be required to address FOF among the older people in residential care in India.

Population-based assessment of awareness of diabetes and diabetes related eye diseases in rural areas in Telangana, India - implications for eye health promotion.

CLINICAL RELEVANCE: Understanding the awareness level of diabetes and diabetes-related eye diseases will help in developing better eye health education programmes and improve health-seeking behaviour in the community. BACKGROUND: Diabetes and diabetes related eye diseases are increasing in numbers both in urban and rural areas in India. There are limited data on awareness of diabetes and diabetes-related eye disease in rural communities of India. This study reports on awareness of diabetes and diabetes-related eye diseases in people aged ≥40 years from two rural districts of Telangana, India. METHODS: A structured questionnaire was used to determine the awareness of diabetes and diabetes-related eye diseases among participants aged ≥40 years in the Khammam and Warangal districts of Telangana, India. Social investigators visited the participant's households and conducted the interviews. A positive response to a question on having heard about diabetes was considered as 'awareness'. For those aware, follow-up questions were asked about the effect of diabetes on vision, frequency of eye examination and source of information. A positive response on a question that diabetes could cause loss of vision was considered as awareness of diabetic eye disease. RESULTS: A total of 3273 participants were interviewed. Among them, 56.2% (n = 1840) were women, 60.6% (n = 1985) had no formal education, and 50.2% (n = 1645) were from the Khammam district. The mean age of the participants was 55.3 years (standard deviation: 11.7 years). Awareness of diabetes was 52.5% (n = 1719). Among them, 1056 participants (61.4%) were aware that diabetes could affect vision. CONCLUSION: Only half of the participants were aware of diabetes and of this substantial proportion of individuals was unaware of potential vision loss due to diabetes. Improving awareness about diabetes and its impact on vision is recommended to prevent potential vision loss in this population.

Effective refractive error coverage and spectacle coverage among school children in Telangana, South India.

BACKGROUND: Uncorrected refractive error (URE) is one of the leading causes of childhood vision impairment. Increasing effective refractive error coverage (e-REC) is one of the main indicators of WHO's 2030 global eye health targets. The aim of this study is to estimate the e-REC and spectacle coverage among school children in Telangana, South India. METHODS: School children aged 4-15 years in the study locations underwent vision screening using 6/12 tumbling E optotype by trained community eye health workers in the schools. Those failing the initial vision screening and/or found to be having eye conditions were referred to a nearby referral centre appropriately, where they underwent detailed eye examination. RESULTS: A total of 774,184 children were screened in schools of which 51.49% were boys. The mean age was 9.40 ± 3.27 years. The prevalence of URE was 1.44% (95%CI:1.41-1.46) of which myopia was 1.38% (95%CI: 1.35-1.41). In multivariate analysis, the risk of myopia was higher among older children (Adj.OR: 17.04; 95%CI: 14.64-19.85), those residing in urban areas (Adj.OR:3.05, 95%CI:2.60-3.57), those with disabilities (Adj.OR:2.61, 95%CI:2.00-3.39) and among girls (Adj.OR:1.30, 95%CI:1.25-1.35) (P < 0.001). The overall e-REC was 56.97% and the spectacle coverage was 62.83%. CONCLUSION: The need for interventions to improve e-REC to achieve 2030 global eye health target is eminent among children in this region. Improving refractive services through school eye health programs could aid in accelerating this process to achieve the target. Myopia being the most common type of RE, the risk factors included increasing age, urban location, and presence of disability.

Variations in the prevalence of vision impairment across regions among school children in Telangana State, South India.

Purpose: Undetected vision impairment (VI) could negatively affect the overall development in children. School vision screening program is a viable and cost-effective approach for the early identification and management of VI. Aim: This study aims to estimate the prevalence of VI, its risk factors, and ocular morbidity among school children in Telangana, South India. Methods: Children aged 4-15 years attending schools in the study area were screened in this study. The vision screenings were performed in schools by trained community eye health workers using 6/12 tumbling E optotypes. Children who failed the test and/or presented with other eye conditions were referred to vision centers or secondary and tertiary eye care centers. A comprehensive eye examination was conducted in these centers, including cycloplegic refraction and fundus examination. Results: A total of 774,184 children, with a mean age of 9.4 ± 3.27 years, were screened. Overall, 51.49% (N = 398,596) were male. In total, 4.33% [N = 33,528; 95% confidence interval (CI): 4.29-4.38] required referral services, while 1.16% (N = 9,002) had a presenting visual acuity of < 6/12. Multivariate analysis showed a high risk of VI among older children [Adj. odds ratio (OR): 5.75; 95% CI: 5.18-6.38], those with disabilities (Adj. OR: 5.12; 95% CI: 4.14-6.33), female gender (Adj. OR: 1.29; 95% CI: 1.24 - 1.35), and those residing in the urban areas (Adj. OR: 2.87; 95% CI: 2.42-3.39). The main cause of VI was uncorrected refractive errors (74.14%). Conclusion: The prevalence of VI among school children was 1.16% in Telangana, South India, and refractive error was the leading cause of VI among this population. Increasing age, urban location, female gender and other disabilities increase the risk of VI among children.

Prevalence, pattern, and compliance with spectacles use among the elderly in homes for the aged in South India: The Hyderabad Ocular Morbidity in Elderly Study (HOMES).

Purpose: This study was conducted to report on the pattern of spectacles use and compliance among the elderly (aged ≥60 years) in homes for the aged in Hyderabad region in Telangana State, India. Methods: Participants were recruited from 41 homes for the aged centres for comprehensive eye health assessments. A questionnaire was used to collect information on current and past use of spectacles, type of spectacles, spectacles provider and amount paid for the spectacles. For those that reported using spectacles in the past, information was collected on the reasons for their discontinuation. Compliance with spectacles use was assessed after eight months of provision of the spectacles. Results: A total of 1182/1513 participants were examined from 41 homes for the aged in Hyderabad, India. The mean age of the participants examined was 75 years (standard deviation (SD): 8.8 years; range: 60-108 years); 764 (64.6%) of them were women and 240 participants (20.3%) had no formal education. The prevalence of spectacles use was 69.9% (95% confidence interval [CI]: 67.1-72.4; n = 825). Bifocals were the most commonly used type of spectacles (86.7%) followed by single vision glasses for distance vision (7.4%). Private eye clinics were the largest service provider (85.5%) followed by local optical outlets (6.9%) and other service providers (7.7%). The prevalence of spectacles compliance was 81.5% (211/259). Conclusion: Use of spectacles and compliance are high among the elderly living in residential care homes in the Hyderabad region. Spectacles use can be further improved by periodic eye assessments along the lines similar to school eye programs, which can immensely benefit this vulnerable, aged population.

Unilateral Vision Loss in Elderly People in Residential Care: Prevalence, Causes and Impact on Visual Functioning: The Hyderabad Ocular Morbidity in Elderly Study (HOMES).

PURPOSE: To investigate the prevalence, causes and impact of unilateral visual impairment (UVI) on visual function in the elderly in 'home for the aged' in Hyderabad, India. METHODS: Participants aged ≥60 years were recruited from 41 'homes for the aged'. All participants had complete eye examinations including visual acuity assessment, refraction, slit-lamp and fundus examination. Unilateral visual impairment (UVI) was defined as presenting VA worse than 6/18 in one eye and presenting VA 6/18 or better in the other eye. Indian Vision Function Questionnaire (INDVFQ) was used for assessing visual functioning. RESULTS: Of the total 1,513 elderly participants enumerated, 1,182 (78.1%) were examined. After excluding 356 participants with VI in the better eye, data were analysed for the remaining 826 participants. The mean age (standard deviation) of these participants was 74.4 ± 8.4 years; 525 (63.6%) were women, and 111 (13.4%) had no schooling. The prevalence of unilateral VI was 38.1% (95% CI: 34.8-41.5; n = 315). Cataract (37.5%; n = 118) was the leading cause of UVI followed by Uncorrected Refractive Error (22.2%; n = 70) and posterior capsular opacification (18.4%; n = 58). The overall INDVFQ score was higher among those with UVI than those without UVI (37.7 versus 34.5; p < .01) suggestive of poor visual functioning. CONCLUSIONS: UVI was common and largely due to avoidable causes among the elderly in residential care with an adverse impact on visual functioning. Screening for vision loss in 'homes for the aged' and the provision of appropriate services should become a routine practice to achieve the goal of healthy aging in India.

Barriers to uptake of referral eye care services among the elderly in residential care: the Hyderabad Ocular Morbidity in Elderly Study (HOMES).

BACKGROUND: To report on the barriers to uptake of eye care services after referral in the elderly in 'homes for the aged' in Hyderabad, India. METHODS: Individuals aged ≥60 years were recruited from 41 'homes for the aged' and were examined in the 'make-shift' clinics in homes. All participants who had vision impairment or needed further eye examination other than spectacles were referred to the higher centres for 'free services'. Three months after the referral, the participants were interviewed and asked about the uptake of services, and their reasons for not attending. RESULTS: In all, 731/1182 (61.8%) participants were referred of which 375 (49.9%) attended. In multiple logistic regression, participants aged ≥80 years were less likely to utilise the services (OR 0.60; 95% CI 0.39 to 0.03). Similarly, the participants living in free homes (OR 3.53; 95% CI 2.15 to 5.79) and subsidised homes (OR 2.24: 95% CI 1.55 to 3.23) and those independently mobile had higher odds for uptake of services (OR 5.74; 95% CI 3.31 to 10.51). The major reasons for not availing the referral services were 'lack of felt need' reported by 136 (45.4%) participants followed by other health issues in 100 (33.4%) participants and non-consenting family members in 49 (16.4%) participants. In all, 14 (4.7%) participants gave other reasons. CONCLUSIONS: The uptake of eye care services in the elderly in residential care remains poor despite the provision of services for free. Lack of felt need for services is the main reason for non-compliance to the referral for care. Counselling on the benefit of interventions could potentially improve referral compliance in this population.

Multimorbidity and multi-disability among the elderly in residential care in India: the Hyderabad Ocular Morbidity in Elderly Study (HOMES).

We report prevalence and risk factors for multimorbidity and multi-disability among elderly people in residential care in the Hyderabad region in South India. In total, 1182 elderly (aged ≥ 60) participants were examined in 41 homes for the aged centres. Detailed interviews were conducted by trained personnel to collect personal and demographic information. A questionnaire was used to assess the history of non-communicable diseases and Washington Disability Questionnaire (WDQ) was administered to assess disabilities. The mean age of the participants was 75.0 years (SD 8.8 years; range: 60-108 years), 35.4% were men, 20.3% had no formal education, 60.7% had school education and 19% had higher education. The prevalence of multimorbidity was 37.6% (95% CI: 34.8-40.4). Prevalence of multi-disability was 23.6% (95% CI: 21.2-26.3; n = 270). In total, 857 (72.5%) participants reported using at least one medication for NCDs. Over a third of the elderly in residential care had multimorbidity, and a quarter of them had multi-disability. A holistic health care system that comprises health and wellness coupled with rehabilitation to address disabilities is needed to achieve healthy aging in elderly in homes for the aged in India.

Visual impairment and refractive errors in school children in Andhra Pradesh, India.

Purpose: Addressing childhood vision impairment (VI) is one of the main goals of the World Health Organization's (WHO) combating blindness strategies. The primary aim of this study was to estimate the prevalence of VI, causes, and its risk factors in school children in Krishna district, Andhra Pradesh, India. Methods: Children aged 4-15 years were screened in schools using the 6/12 Snellen optotype by trained community eye health workers, and those who failed the test and those reported or found to have obvious eye conditions were referred to primary (VC), secondary (SC), or tertiary (TC) care centre appropriately, where they underwent a complete eye examination including cycloplegic refraction and fundus examination. Results: A total of 56,988 children were screened, of whom 51.18% were boys. The mean age was 9.69 ± 3.26 years (4-15 years). Overall, 2,802/56,988 (4.92%) children were referred to a VC, of which 632/56,988 (1.11%) required referral to SC/TC. PVA of <6/12 was found in 1.72% (95% confidence interval [CI]: 1.61-1.83). The prevalence of refractive error (corrected and uncorrected) was 2.38% (95% CI: 2.26-2.51) and myopia was 2.17% (95% CI: 2.05-2.29). In multivariable analysis, older children, those in urban schools, private schools, and children with a disability had an increased risk of VI and myopia. Additionally, the risk of myopia was higher among girls than boys. Of those referred and reached SC/TC, 73.64% were due to avoidable causes. Conclusion: Childhood VI prevalence was 1.72% in this region. Uncorrected refractive error (URE) was the major cause of VI in children. Older age, schools in urban locations, private schools, and the presence of disability were associated with the risk of VI among children.

Population-based assessment of barriers for uptake of eye care services among elderly people: Findings from rapid assessment of visual impairment studies from Telangana, India.

Purpose: To report the barriers for seeking eye care among the elderly population aged ≥60 years with avoidable vision impairment (VI) in the South Indian state of Telangana. Methods: A total of 3640 participants aged ≥60 years were recruited using cluster-random sampling. Demographic information, including presenting visual acuity, was measured using the standard Rapid Assessment of Visual Impairment (RAVI) protocol. "Avoidable VI" was considered if the VI was due to cataract or uncorrected refractive error (URE). A detailed interview was conducted using a validated questionnaire to report the barriers for not seeking eye care. Data were analyzed using the Stata statistical software version 14. Results: Prevalence of avoidable VI was 30.2% (95% CI: 28.02-31.06; n = 1102). Among those who noticed decreased vision (n = 1074), only 392 participants (36.4%) reported that they felt the need for seeking eye care. The major barriers for not seeking eye care were: cannot afford the consultation fee and services (42.0%) and no escort (25.7%). Overall, the personal barriers (57.9%) were the major reason for not seeking care, followed by economic barriers (42.0%). No significant difference was reported in barriers between the participants with unilateral and bilateral VI (>0.05). Conclusion: Overall, among the elderly people, personal and economic barriers were the major reason for not seeking eye care. Health care providers and policymakers should focus on newer models of eye care delivery to ensure better accessibility and uptake of care by the elderly people.

Awareness of cataract and glaucoma in two rural districts of Telangana, India.

PURPOSE: To determine the level of awareness of cataract and glaucoma and identify the determinants of awareness in two rural districts of Telangana, India. METHODS: A population-based cross-sectional study was conducted using the rapid assessment of visual impairment (RAVI) methodology in Khammam and Warangal districts. A validated questionnaire was administered to participants aged 40 years and above to assess the level of awareness of cataract and glaucoma. RESULTS: The awareness questionnaire was administered to 3273 participants of whom 1433 (43.8%) were men, 1985 (60.6%) of them had no education, and 1645 (50.3%) were from Khammam district. In total, 2539/3273 (77.6%; 95% confidence intervals (CI): 76.1- 79.0%) participants reported awareness of cataract. Awareness of cataract was higher in Khammam compared to that in Warangal (84.4% versus 70.6%; P < 0.01). Only 41/3273 (1.25%, 95% CI: 0.90-1.69%) participants were aware of glaucoma. Awareness of glaucoma was also higher in Khammam (1.88% versus 0.61%; P < 0.01). Younger age groups, men, any level of education, and residing in Khammam were factors associated with awareness of cataract. Only having any level of education and residing in Khammam were associated with awareness of glaucoma. CONCLUSION: Awareness of cataract was high, but awareness of glaucoma was very poor. There is a need to spread awareness about these potentially blinding conditions. Moving forward, this can be a critical step in developing a preventive eye care strategy to achieve universal eye health in India.

Awareness on Eye Donation in the North-eastern State of Tripura, India - The Tripura Eye Survey.

PURPOSE: To determine the awareness on eye donation and willingness to pledge eyes for donation among the population aged ≥40 years in the northeastern state of Tripura, India. METHODS: A population-based cross-sectional study was carried out among 2,500 participants. The investigators conducted a detailed interview on awareness of eye donation and willingness to pledge eyes for donation. 'Awareness' was defined as having heard about eye donation. Those who reported awareness of eye donation were asked a question on willingness to pledge their eyes. RESULTS: A total of 2,440/2,500 (97.6%) participants responded to the questionnaire. Among these, 1,216 (49.8%) participants were men, and 859 (35.2%) had no education. The mean age of the participants was 54.7 years (standard deviation:12.1 years). Overall, 61.4% (95% CI:59.5-63.4; n = 1,499) reported awareness of eye donation; of those only 3.8% (95% CI:2.9-4.9; n = 57) were willing to pledge their eyes for donation. On multivariable analyses, the odds of awareness were higher among those who had school education (OR:2.12; 95% CI: 1.73-2.56) or higher education (OR:11.79; 95% CI:7.35-18.93). Deformity associated with eye donation (n = 327;76.9%) followed by religious reasons (n = 63; 14.8%) and a belief that those who donate eye are 'born blind in the next birth' (n = 23; 5.4%) were the main reasons for lack of willingness to pledge their eyes for donation. CONCLUSIONS: Although the awareness regarding eye donation was satisfactory, there was lack of willingness to pledge eyes for donation. There is a need for focussed information, education, and communication campaigns to encourage eye donation in Tripura.

A Population-Based Cross-Sectional Study of Visual Impairment in West Godavari and Krishna Districts in Andhra Pradesh: Akividu Visual Impairment Study (AVIS).

PURPOSE: To report the prevalence and causes of visual impairment (VI) among those aged ≥40 years in West Godavari and Krishna districts in Andhra Pradesh, India. METHODS: Trained teams visited the households in the selected clusters and conducted eye examinations. Presenting visual acuity (PVA) was assessed for distance and near. Torchlight examination was conducted to assess the anterior segment. Non-mydriatic retinal images were also obtained. VI was defined as PVA worse than 6/18 in the better eye. It included Moderate VI (PVA worse than 6/18 to 6/60), Severe VI (PVA worse than 6/60 to 3/60) and Blindness (PVA worse than 3/60). Multiple logistic regression analysis was conducted to assess the risk factors for VI. RESULTS: In total, 2587/3000 (86.2%) participants were examined. Of this, 1406 (54.4%) were women and 1224 (47.3%) had no education. The age- and gender-adjusted prevalence of VI was 12.8% (95% CI: 11.5-14.1). Compared to the 40-49-year age group, the odds of having VI among those aged 50-59 years, 60-69 years and ≥70 years were 2.93 (95% CI: 1.91-4.52), 6.53 (95% CI: 4.31-9.91) and 17.45 (95% CI: 11.50-26.46), respectively. Those respondents who had no education had a higher odds (OR: 1.73; 95% CI: 1.34-2.23) of VI compared to those who were educated. Cataract (62.4%) and uncorrected refractive errors (29.8%) were the leading causes of VI. Over 90% of the VI was due to avoidable causes. CONCLUSION: VI is a major public health challenge in Andhra Pradesh. Over 90% of this burden is avoidable and can be eliminated by low-cost interventions such as spectacles and cataract surgery.

Population-based assessment of prevalence of spectacle use and effective spectacle coverage for distance vision in Andhra Pradesh, India - Akividu Visual Impairment Study.

CLINICAL RELEVANCE: Effective spectacle coverage is a useful indicator to assess the coverage of refraction services in a given region. We found a low coverage in the Akividu region suggesting a need to develop effective refraction services. BACKGROUND: To assess the prevalence of spectacle use and effective spectacle coverage for distance vision among people aged 40 years and older in the Indian state of Andhra Pradesh. METHODS: A population-based cross-sectional survey was carried out in the Akividu region in West Godavari and Krishna districts. The study teams visited selected households and conducted eye examinations in the selected clusters. A structured questionnaire was used to collect information on spectacle use. 'Met Need' was defined as unaided VA worse than 6/12 but improved to 6/12 or better with their current spectacles. 'Unmet Need' was defined as unaided VA worse than 6/12 but improved to 6/12 with pinhole, among those not using spectacles. The 'Under-met Need' was defined as aided VA worse than 6/12 but improving with pinhole to 6/12 or better. Based on these definitions, Effective Refractive Error Coverage (e-REC) is calculated as: e-REC (%) s = ((met need)/(met need + under-met need + unmet need)) X100. RESULTS: Of 3,000 enumerated from 60 clusters, 2,587 (86.2%) participants were examined. The prevalence of current spectacle use was 43.1% (95% CI:41.2-45.0). The e-REC was 37.4%. It was also lower in men compared to women and among those without any education. Participants who had cataract surgery in either eye had similar e-REC compared to those who were not operated. CONCLUSION: Though spectacle use was found to be high, there is a still large unmet need for refractive correction for distance. Effective service delivery models to provide refraction and spectacle dispensing services are needed to achieve universal eye health coverage in the region.

IMI Impact of Myopia.

The global burden of myopia is growing. Myopia affected nearly 30% of the world population in 2020 and this number is expected to rise to 50% by 2050. This review aims to analyze the impact of myopia on individuals and society; summarizing the evidence for recent research on the prevalence of myopia and high myopia, lifetime pathological manifestations of myopia, direct health expenditure, and indirect costs such as lost productivity and reduced quality of life (QOL). The principal trends are a rising prevalence of myopia and high myopia, with a disproportionately greater increase in the prevalence of high myopia. This forecasts a future increase in vision loss due to uncorrected myopia as well as high myopia-related complications such as myopic macular degeneration. QOL is affected for those with uncorrected myopia, high myopia, or complications of high myopia. Overall the current global cost estimates related to direct health expenditure and lost productivity are in the billions. Health expenditure is greater in adults, reflecting the added costs due to myopia-related complications. Unless the current trajectory for the rising prevalence of myopia and high myopia change, the costs will continue to grow. The past few decades have seen the emergence of several novel approaches to prevent and slow myopia. Further work is needed to understand the life-long impact of myopia on an individual and the cost-effectiveness of the various novel approaches in reducing the burden.

Near-vision impairment and effective near-vision spectacle coverage in two districts in Telangana, India: a population-based cross-sectional study.

OBJECTIVES: To investigate the prevalence of near-vision impairment (NVI) and effective spectacle coverage for near vision in those aged ≥40 years in Khammam and Warangal district in Telangana, India. DESIGN: A population-based cross-sectional study. SETTING: Khammam and Warangal district in Telangana, India. PARTICIPANTS: Of 6000 people enumerated, 5357 were examined (89%). 4526 participants without distance vision impairment were included in the analysis. MAIN OUTCOME MEASURES: The study teams visited selected households and conducted eye examinations. NVI was defined as binocular presenting near vision worse than N6. 'Unmet need' was deemed to be present if the unaided near vision was worse than N6 and improved to N6 with near correction among the participants who did not have spectacles for near vision. 'Met need' was deemed to be present when unaided near vision was worse than N6 but improving to N6 with their spectacles. The 'undermet need' was deemed to be present when aided near vision was worse than N6 but improved to N6 with correction. Based on these definitions, e-near-vision coverage (%) is calculated as follows: e-NVC (%)=met need/(met need+undermet need+unmet need) × 100. RESULTS: The mean age was 53.5 years (SD: 10.8 years), 2534/4526 (55.8%) were women, 1819/4526 (41.8%) had at least primary school education and 2368/4526 (52.3%) were from the Khammam district. The prevalence of NVI was 55.8% (95% CI 72.5 to 75.1; n=3343). Overall, the e-NVC (%) was 31.8%. It was 40.0% in Khammam and 23.2% in Warangal. CONCLUSION: NVI is common in Khammam and Warangal districts in Telangana with inadequate effective near-vision coverage. Effective service delivery models are needed to reach out and provide services to address NVI to achieve universal eye health coverage in the region.

Prevalence of disabilities and non-communicable diseases in an elderly population in the Telangana state, India: a population-based cross-sectional study.

OBJECTIVES: To assess the prevalence of disabilities (vision, hearing, mobility, cognitive, self-care and communication) and non-communicable diseases (NCDs) among the elderly population in two districts in Telangana, India. DESIGN: Population-based cross-sectional study using a cluster random sampling method to select the study clusters. SETTING: Elderly population in Khammam and Warangal districts were recruited. Detailed interviews were conducted by trained community health workers. Personal and demographic information such as age, gender, level of education and a self-report of NCDs was collected. The Washington Disability Questionnaire was administered to assess the presence of disabilities. PARTICIPANTS: 1821 participants aged ≥60 years, 54.5% were women, and 73.3% had no education. PRIMARY OUTCOME MEASURE: Prevalence of disabilities and NCDs. RESULTS: Overall, the prevalence of at least disability was 20.3% (95% CI 16.3 to 24.9). The prevalence of self- reported disabilities were: seeing (5.9%; 95% CI 4.4 to 7.8), mobility (12.8%; 95% CI 9.7 to 16.8), hearing (3.6%; 95% CI 2.7 to 4.8), cognition (4.8%; 95% CI 3.5 to 6.7), self-care (3.3%; 95% CI 2.3 to 4.7) and communication (1.8%; 95% CI 1.2 to 2.6). Overall, the prevalence of at least one NCD was 34.2% (95% CI 30.9 to 37.7). Hypertension was the most common systemic condition (25.4%; 95% CI 22.4 to 28.7), followed by diabetes (9.0%; 95% CI 7.3 to 11.0), and body pains (muscle-skeletal) (9.9%; 95% CI 8.1 to 12.2). CONCLUSION: Every fifth elderly person in the districts of Khammam and Warangal in Telangana had at least one self-reported disability. Besides, a third of the elderly had at least one NCD. There is a definite need to develop comprehensive public health strategies to address disabilities and NCDs in Telangana.

Agreement and diagnostic accuracy of vision screening in preschool children between vision technicians and spot vision screener.

Purpose: Screening preschool children for vision-related disorders poses a challenge. This study is designed to determine the agreement and diagnostic accuracy of the spot vision screener (SVS) in screening preschool children compared to screening procedure by vision technicians (VT). Methods: This study was conducted as a part of the ongoing study titled "Initiative for Screening Children for Refractive Errors and other Eye Health Needs (I-SCREEN)." Children from 33 Anganwadis (preschools) in two districts, Adilabad district of Telangana and Krishna district of Andhra Pradesh, in South India, underwent eye health screening by a VT and by a trained community eye health workers (CEHW) using the SVS. Findings were compared for agreement and diagnostic accuracy of assessment. Results: A total of 976 preschool children were screened by the VT and separately by the CEHW using the SVS in Adilabad (15 schools) and Krishna (18 schools) districts. The overall mean age of these children was 2.5 years (SD ± 1.3 years). There were 48 (4.9%) referrals by VT compared to 105 (10.8%) referrals by CEHW using SVS. The overall sensitivity of SVS was 91.7% (95% CI: 80%-97.7%) and the specificity was 93.4% (95% CI: 91.6%-94.9%). Positive predictive value was 41.9% (95% CI: 32.3%-51.9%) and negative predictive value was 99.5% (95% CI: 98.8%-99.9%) with a moderate agreement (0.54; 95% CI 0.49-0.64) between VT screening and screening with SVS. Conclusion: The SVS showed good diagnostic accuracy and agreement in screening for possible vision-related disorders in preschool children.

Prevalence and causes of vision loss in sub-Saharan Africa in 2015: magnitude, temporal trends and projections.

BACKGROUND: This 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. METHODS: A systematic review and meta-analysis assessed the prevalence of blindness (presenting distance visual acuity <3/60 in the better eye), moderate and severe vision impairment (MSVI; presenting distance visual acuity <6/18 but ≥3/60) and mild vision impairment (MVI; presenting distance visual acuity <6/12 and ≥6/18), and also near vision impairment (
