RESUMEN

Purpose: India has the largest population of youth in the world, thereby making them important contributors to the "India of Tomorrow". Over 80% of knowledge gained is by the visual sense, thereby making school screening programs a necessity in our country. Data from the pre-COVID era, that is, 2017-18 was collected from close to 19,000 children in Gurugram, Haryana, a tier two city in National Capital Region, India. A similar prospective observational study is planned post COVID-19 (2022-23) for further analysis to depict the impact of COVID-19 in these areas. Methods: The program They See, They Learn was set at government schools in the area of operations (district of Gurgaon, Haryana), where the children and their families were unable to afford eye care services. All children who were screened underwent a comprehensive eye examination at the school premises itself. Results: A total of 18,939 students were screened over a period of 18 months, covering a total of 39 schools in the Gurugram belt, in the first phase of the program. Eleven point eight percent (n = 2254) of all school students had some form of refractive error. Girl students were found to have a higher refractive error rate (13.3%) compared to boy students (10.1%) across the schools screened. Myopia was the most common type of refractive error. Conclusion: School students require perfect vision or else they can be discouraged and may become a major burden to the economy of any developing nation. A school screening program aiming at populations that cannot afford such basic needs like spectacles is a must in all zones of the country.

RESUMEN

PURPOSE: Myopia prevalence has increased in the UK at age 10-16y, but little is known about younger children. We hypothesise that if the 'myopia epidemic' is affecting young children, then there will be increasing rates of bilateral reduced unaided vision (V) at vision screenings of children 4-5 years of age. METHODS: Retrospective anonymised data from computerised vision screening at age 4-5 years were analysed from serial cross-sectional data. Refractive error is not assessed in UK vision screening, so vision was investigated. Data were only included from schools that screened every year from 2015/16 to 2021/22. The criterion used was unaided monocular logMAR (automated letter-by-letter scoring) vision >0.20 in both the right and left eyes, so as to maximise the chances of detecting bilateral, moderate myopia rather than amblyopia. RESULTS: Anonymised raw data were obtained for 359,634 screening episodes from 2075 schools. Once schools were excluded where data were not available for every year and data were cleaned, the final database comprised 110,076 episodes. The proportion (percentage and 95% CI) failing the criterion from 2015/16 to 2021/22 were 7.6 (7.2-8.0), 8.5 (8.1-8.9), 7.5 (7.1-7.9), 7.8 (7.4-8.2), 8.7 (8.1-9.2), 8.5 (7.9-9.0) and 9.3 (8.8-9.7), respectively. The slope of the regression line showed a trend for increasing rates of reduced bilateral unaided vision, consistent with increasing frequency of myopia (p = 0.06). A decreasing linear trendline was noted for children 'Under Professional Care'. CONCLUSIONS: For children 4-5 years of age, there were signs of reduced vision over the last 7 years in England. Consideration of the most likely causes support the hypothesis of increasing myopia. The increase in screening failures highlights the importance of eye care in this young population.

RESUMEN

Clinical relevanceConvergence insufficiency (CI) at an early age can lead to learning difficulties affecting school performance. The aim of this study was to examine the prevalence of CI in a non-clinical population of Spanish children using well defined clinical criteria and to determine whether sex is a risk factor.MethodsVisual acuity and binocular vision tests were performed in 628 children aged 6–14 years (mean age 9.6 ± 1.3 years) at three schools in the Madrid Community, Spain. To assess CI prevalence we used CITT (Convergence Insufficiency Treatment Trial) criteria. The three signs considered were: i) exophoria at least 4∆ greater at near than at far; ii) near break point of convergence (NPC) ≥ 6 cm; and iii) reduced positive fusional vergence (PFV) at near (≤ 15∆ base-out break or failed Sheard's criterion).ResultsThe CI prevalence detected was 5.30% (33 children). Proportions of children with one or two signs of CI were 23.76% (148 children) and 12.20% (76 children), respectively. No differences in these CI rates by sex were detected.ConclusionThe clinically significant CI prevalence observed here suggests the need for more binocular vision screening programmes in school settings.

RESUMEN

OBJECTIVE: To identify the prevalence of adolescent idiopathic scoliosis (AIS) and potential disease-related factors in children aged 11 to 16 years in the Huangpu district, Shanghai, China. METHODS: A total of 10,731 children (5,518 boys and 5,213 girls) were screened in the year of 2019. The screening process included a bending forward test and scoliometer measurements. The children who were deemed to be at risk for scoliosis from the screening were referred for a X-ray examination to confirm the diagnosis. Data from basic and clinical characteristics of the screened children were collected. RESULTS: 214 children (138 girls and 76 boys, P<0.05) were diagnosed with scoliosis with a prevalence of 2.00%. The mean angel was 15.61°. The groups with the highest prevalence were girls aged 14 and boys aged 15. CONCLUSION: The prevalence of AIS in Huangpu district, Shanghai, China is 2.00% and is moderatley high, and it can occur more often in female children.

RESUMEN

Purpose: To profile the presentation of ocular conditions among school children aged 6 to 17 years from the south Indian state of Tamil Nadu. Methods: The study was conducted as part of a school eye health program in Kanchipuram district, Tamil Nadu that aimed to address the refractive needs of children (6-17 years) between July 2016 and June 2019. The study followed a three-phase protocol, which included visual acuity test, modified clinical test, color vision test, binocular vision assessment, objective and subjective refraction, dispensing spectacles, posterior segment evaluation using direct ophthalmoscopy, and referral to the base hospital. The demographics, clinical details, and ocular conditions (classified under 16 categories) were analyzed. Profiling and association of ocular conditions among different locations, types of schools, class grades, and gender were presented. Results: Data of 2,45,565 children were analyzed from 1,047 schools, of which 4,816 (1.96%) children were identified with ocular conditions other than refractive errors. The common reasons for referral were high myopia 901 (0.37%), strabismus 819 (0.33%), and amblyopia 691 (0.28%). Retinal problems (odds ratio [OR]: 1.65, 95% confidence interval [CI]: 1.22-2.22, P = 0.001) and strabismus (OR: 1.41, 95% CI: 1.21-1.65, P < 0.001) were the conditions prevalent in the rural location. Cataract and related conditions (OR: 5.73, 95% CI: 4.10-8.01, P < 0.001) and retinal problems (OR: 4.76, 95% CI: 3.37-6.72, P < 0.001) were common in children studying in public schools. Of the 16 categories, 13 conditions were seen among primary school children. Vernal keratoconjunctivitis (OR: 3.64 95% CI: 2.12-6.23 P < 0.001) was common among males. Conclusion: The study profiled ocular conditions among school children. Most ocular conditions warrant prolonged care and specialty eye care services. Ensuring the availability of such services and follow-up after school eye screening would safeguard the visual development of these children.

RESUMEN

Early detection of scoliosis with school screening and quick, easy, and reliable assessment of its progress are of paramount importance in the management of patients. There have been several tools described, with the most common being the analog scoliometer. Most recently, smartphone applications have entered this area with and without the use of sleeves for the device. There is no research that has evaluated the accuracy of measurements both left and right in either digital or analog devices. In this study, we evaluated the reliability and validity of a new digital scoliometer called the Scolioscope. Thirty subjects were included for the intra-rater reliability study. ICC values >0.9 were calculated both for same-day and between-day measurements. The device was highly accurate with an average difference from the ones set on the sine bar of 0.03° for right-side measurements and 0.18° for the left. These measurements suggest a highly accurate and reliable tool.

RESUMEN

Programs offering reproductive genetic carrier screening (RGCS) to high school students within the Ashkenazi Jewish community in several countries including Canada and Australia have demonstrated high uptake and retention of educational messages over time. This study was undertaken to evaluate whether testing for an expanded number of conditions in a high school setting would impact the effectiveness of education. In this questionnaire-based study, genetic carrier testing for nine conditions was offered to 322 year 11 students from five high schools, with students attending a compulsory 1-h education session prior to voluntary testing. Comparison of pre- and post-education measures demonstrated a significant increase in knowledge, positive attitudes, and reduced concern immediately after the education session. Retention of knowledge, measures of positive attitude, and low concern over a 12-month period were significantly higher than baseline, although there was some reduction over time. In total, 77% of students exhibited informed choice regarding their intention to test. A significant increase in baseline knowledge scores and positive attitude was also demonstrated between our original 1995 evaluation (with testing for only one condition) and 2014 (testing for nine conditions) suggesting community awareness and attitudes to RGCS have increased. These findings validate the implementation of effective education programs as a key component of RGCS and are relevant as gene panels expand with the introduction of genomic technologies.

RESUMEN

OBJECTIVE: To synthesize and appraise economic evaluations of vision screening to detect vision impairment in children. METHODS: Literature searches were conducted on seven electronic databases, grey literature, and websites of agencies conducting health technology assessments. Studies were included if they (1) were full, comparative economic evaluations that used cost-utility, cost-benefit, cost-effectiveness, cost-consequence, or cost-analysis methods; (2) described screening services designed to detect amblyopia, strabismus, or uncorrected refractive errors in children under 6 years of age; and (3) published after 1994. High-quality studies were synthesized descriptively. Currencies were reported in 2019 Canadian dollars. Quality was assessed with the Pediatric Quality Appraisal Questionnaire (PQAQ). RESULTS: Vision screening services were conducted by paid staff, volunteers, or health care professionals in schools or clinics. Thirteen studies were published from five countries: China (n = 1), United States (n = 4), United Kingdom (n = 1), Canada (n = 1), and Germany (n = 6). Analytical techniques included cost-utility/cost-effectiveness combination (n = 2), cost-effectiveness analysis (n = 7), cost-utility analysis (n = 1), cost-benefit analysis (n = 1), cost-consequence analysis (n = 1), and cost analysis (n = 1). Incremental cost-effectiveness ratios ranged from C$1,056 to C$151,274 per additional case detected/prevented and from C$9,429 to C$30,254,703 per additional QALY gained, depending on the type of screening service and comparator. Six studies were determined to be of high quality. CONCLUSION: Vision screening to detect amblyopia for young children may be cost-effective compared with no screening if amblyopia reduced quality of life. Studies varied significantly in the type of screening services and comparators used. Methodological limitations were common. Future studies would be aided immensely by prospective studies on the impact of amblyopia on the health-related quality of life of young children and guidelines on the effective conduct of vision screening.

RéSUMé: OBJECTIF: Synthétiser et évaluer des évaluations économiques de dépistages visuels visant à détecter la déficience visuelle chez les enfants. MéTHODE: Nous avons interrogé sept bases de données électroniques, la littérature grise et les sites Web d'organismes effectuant des évaluations des technologies de la santé. Nous avons inclus les études correspondant aux critères suivants : (1) évaluations économiques comparatives exhaustives utilisant l'analyse coûts-utilité, coûts-bénéfices, coûts-efficacité ou coûts-conséquences ou l'analyse des coûts; (2) décrivant des services de dépistage visant à détecter l'amblyopie, le strabisme ou les anomalies de la réfraction non corrigées chez les enfants de moins de six ans; et (3) publiées après 1994. Nous avons fait la synthèse descriptive des études de haute qualité. Les devises ont été converties en dollars canadiens de 2019. Nous avons évalué la qualité des études à l'aide de l'outil PQAQ (Pediatric Quality Appraisal Questionnaire). RéSULTATS: Les services de dépistage visuel étaient offerts par du personnel rémunéré, des bénévoles ou des professionnels de santé dans des écoles ou des cliniques. Treize études ont été publiées dans cinq pays : Chine (n = 1), États-Unis (n = 4), Royaume-Uni (n = 1), Canada (n = 1) et Allemagne (n = 6). Les techniques d'analyse employées étaient la combinaison analyse coûts-utilité/analyse coûts-efficacité (n = 2), l'analyse coûts-efficacité (n = 7), l'analyse coûts-utilité (n = 1), l'analyse coûts-avantages (n = 1), l'analyse coûts-conséquences (n = 1) et l'analyse des coûts (n = 1). Les rapports coût-efficacité différentiels s'échelonnaient entre 1 056 $ CA et 151 274 $ CA par cas supplémentaire détecté/prévenu et entre 9 429 $ CA et 30 254 703 $ CA par année de vie pondérée par la qualité (AVPQ) supplémentaire gagnée, selon le type de service de dépistage et le comparateur. Six études ont été jugées être de haute qualité. CONCLUSION: Comparativement à l'absence de dépistage, les dépistages visuels pour détecter l'amblyopie chez les jeunes enfants peuvent être efficaces par rapport à leur coût lorsque l'amblyopie réduit la qualité de vie. Le type de services de dépistage et les comparateurs utilisés variaient considérablement d'une étude à l'autre. Les contraintes méthodologiques étaient courantes. Les études futures seraient grandement favorisées par des études prospectives des incidences de l'amblyopie sur la qualité de vie liée à la santé chez les jeunes enfants et par des lignes directrices sur l'exécution efficace des dépistages visuels.

RESUMEN

BACKGROUND: Visual health is linked to school achievement, quality of life and productivity. But eye screening in school children is not routinely done in most Ethiopian schools. This study was done to determine prevalence and pattern of ocular morbidity among school children in Roman Dega-Kedida, Southern Ethiopia. METHOD: This was a cross-sectional study. All children aged 16 years or less, attending the school during the study period were included. Data entry and statistical analyses were performed using SPSS Version 16. A P - value of < 0.05 was considered statistically significant. RESULT: A total of 778 children participated in this study. The female to male ratio was 1.06:1. The mean age was 11.34(±2.31) years. A total of 201 (25.8%) children had ocular morbidities. The most common was trachoma found in 85(10.9%). Of these, 49(56.5%) had active trachoma, while 37(43.5%) had either trachoma scar or trachomatous trichiasis. Allergic conjunctivitis was found in 49(6.3%), refractive error in 37(4.8%), and xerophthalmia in 17(2.2%) children. Visual impairment in one or both eyes was found in 41(5.3%) children. Thirty-two children (4.1%) had bilateral Visual impairment of which 6(18.8%) had moderate to severe visual impairment. The cause of visual impairment was refractive error in 37(90.2%), corneal opacity in 3(7.3%) and cataract in 1(2.4%) child. CONCLUSION: Most of the ocular diseases observed were either preventable or treatable. Health education to the community and establishing regular school screening program is recommended.

RESUMEN

BACKGROUND: Little is known about patients' understanding of adolescent idiopathic scoliosis (AIS). This paper aims to develop and validate the Scoliosis Misconception Scale (SMS) and to explore patients' level of misconception about AIS. METHODS: A total of 195 patients who were newly referred with newly diagnosed AIS were recruited to assess their levels of misconception and psychological distress before and after their first consultation with a specialist. The 17-item SMS was administered to assess patients' level of misconception about AIS and the Kessler Psychological Distress Scale (K10) was used to measure their level of distress. RESULTS: According to the Item Response Theory, all items were within the acceptable range from -3.69 to 2.39 for difficulty parameters, which determined the difficulty of the scale, while most of the items were within the acceptable range from 0.11 to 1.54 for the discrimination parameters, which determined the rate at which the probability of endorsing a correct item changes given ability levels. Internal consistency by marginal reliability was 0.66. One-sample t test revealed that participants on average scored 6.79 (SD = 2.12) before the first clinic session and 6.45 (SD = 2.51) after the first clinic session, both significantly higher than 0 [t(75) = 27.86, p < .001; t(75) = 22.43, p < .001]. CONCLUSIONS: Despite a longstanding clinical model that functions well to treat AIS, most patients still have significant misconceptions about the condition. This highlights the necessity to assess patients' knowledge level of a medical condition and potential generalisability of misconception-distress link to the forefront across other illnesses.

RESUMEN

Undiagnosed hearing deficits hamper a child's ability to learn. Hearing screening in school aged children helps detect educationally significant hearing loss and prevents negative impacts on academic achievement. The main purpose of this study was to improve early detection and assess the incidence of hearing disorders in first-graders from rural areas and small towns in the Malopolskie Voivodeship of Poland. There were 5029 children aged 6-7 years. Hearing thresholds were measured over the frequency range 0.5-8 kHz. A result was considered positive (abnormal) if the hearing threshold was worse than 20 dB HL at one or more frequencies. The prevalence of hearing loss was estimated in terms of four-frequency hearing loss, high-frequency hearing loss, and low-frequency hearing loss. Parents filled in a brief audiological questionnaire. The analysis was performed using IBM SPSS Statistics, version 24. Of all the children, 20.5% returned a positive result and were referred for further audiological diagnoses. The estimated prevalence of hearing loss was 11.6%, made up of 6.5% with FFHL, 7.6% with HFHL, and 8.2% with LFHL. This study showed that large numbers of children in the district had hearing problems. Adoption of hearing screening in primary schools is recommended as a routine procedure within preventive pediatric health care.

RESUMEN

BACKGROUND: Strabismus is the leading risk factor for amblyopia, which should be early detected for minimized visual impairment. However, traditional school screening for strabismus can be challenged due to several factors, most notably training, mobility and cost. The purpose of our study is to evaluate the feasibility of using a smartphone application in school vision screening for detection of strabismus. METHODS: The beta smartphone application, EyeTurn, can measure ocular misalignment by computerized Hirschberg test. The application was used by a school nurse in a routine vision screening for 133 elementary school children. All app measurements were reviewed by an ophthalmologist to assess the rate of successful measurement and were flagged for in-person verification with prism alternating cover test (PACT) using a 2.4Δ threshold (root mean squared error of the app). A receiver operating characteristic (ROC) curve was used to determine the best sensitivity and specificity for an 8Δ threshold (recommended by AAPOS) with the PACT measurement as ground truth. RESULTS: The nurse obtained at least one successful app measurement for 93% of children (125/133). 40 were flagged for PACT, of which 6 were confirmed to have strabismus, including 4 exotropia (10△, 10△, 14△ and 18△), 1 constant esotropia (25△) and 1 accommodative esotropia (14△). Based on the ROC curve, the optimum threshold for the app to detect strabismus was determined to be 3.0△, with the best sensitivity (83.0%), specificity (76.5%). With this threshold the app would have missed one child with accommodative esotriopia, whereas conventional screening missed 3 cases of intermittent extropia. CONCLUSIONS: Results support feasibility of use of the app by personnel without professional training in routine school screenings to improve detection of strabismus.

RESUMEN

BACKGROUND: IgA nephropathy (IgAN) is characterized by predominant mesangial IgA deposition. Some patients with IgAN demonstrate IgA deposition in glomerular peripheral capillaries (cap-IgA). The clinicopathological significance of cap-IgA remains incompletely investigated in children. METHODS: We retrospectively analyzed 503 consecutive cases of biopsy-proven childhood IgAN between July 1976 and June 2013 to compare clinical and pathological features between IgAN patients with and without cap-IgA. RESULTS: Among the 503 patients, 30 (6.0%) had cap-IgA. We found significant differences in proteinuria (2.0 vs. 0.5 g/day/m2, p < 0.0001), time from onset to kidney biopsy (2.2 vs. 8.3 months, p < 0.0001), and rate of proteinuria remission after treatment (23.3% vs. 48.0%, p = 0.007) between both groups. Pathological analysis revealed significant differences in M1 (83.3% vs. 56.0%, p = 0.002), ratio of subendothelial electron dense deposits (EDDs, 58.6% vs. 16.5%, p < 0.0001) and subepithelial EDDs (48.3% vs. 16.5%, p = 0.0001), and glomerular basement membrane (GBM) lysis (58.6% vs. 27.1%, p = 0.0006) between both groups. More than half of cap-IgA patients (17/30, 56.7%), whereas only 26.2% of non-cap-IgA patients (124/473), were treated with immunosuppressive treatments. Six of 30 cases (20%) with cap-IgA reached glomerular filtration rate (GFR) categories G3a-G5 (estimated GFR < 60 ml/min/1.73 m2) at most recent observation (mean observation period: 7.0 ± 4.0 years). According to Kaplan-Meier analysis, patients with cap-IgA had significantly lower kidney survival curves than non-cap-IgA patients (72.8% vs. 97.2% at 10 years, p < 0.0001). CONCLUSIONS: Cap-IgA is associated with acute inflammation with GBM changes, resulting in refractory heavier proteinuria. Cap-IgA may represent a poor prognostic factor.

RESUMEN

PURPOSE: To measure sensitivity and specificity of vision screeners in identifying children with visual impairment and positive signs and symptoms and assess association of effectiveness with individual characteristics of screeners and type of schools screened. METHODS: A total of 1096 children from age 5 to 15 years of age were screened. A total of 396 children were screened from a municipal school, 200 children from a government-aided school, and 500 children from a private school were screened. Four persons with basic 12th standard science qualification willing to be a part of school eye health program were selected who carried out screening in school children after receiving appropriate training. RESULTS: The two vision screeners who had a background of conducting community eye health programs and worked in eye hospital had 100% sensitivity and specificity for presenting visual acuity, squint detection, and blurring. The screening by these screeners was done in private and semi-private schools, respectively. The other two screeners with no such background conducting screening in government schools had 60% and 75% sensitivity in detecting presenting visual acuity, respectively. CONCLUSION: People with a background of organizing community eye health programs and those working in eye hospitals are the best candidates for being trained as new cadre of vision screeners with best results being obtained in private and government-aided schools.

RESUMEN

OBJECTIVES: To determine the prevalence and causes of visual impairment in hearing-impaired students in Lagos, Nigeria and to assess their level of ophthalmic care utilization. METHODS: Descriptive cross sectional study carried out in a primary school for hearing impaired students in Lagos, Nigeria. Socio-demographic characteristics, medical and ocular history were obtained. Ocular examination comprised of distance and near visual acuity assessment; cover tests; anterior segment examination and direct fundoscopy. Visually impaired students had cycloplegic refraction, dilated fundoscopy and subjective refraction. In-depth interviews were carried out for parents of students requiring referral for further eye care. RESULTS: One hundred and nine students participated in the study. The prevalence of visual impairment was 19%. The causes of visual impairment were refractive error (11%), amblyopia (6%), cataract (1%) and macular scarring (1%). A lower mean age (p = 0.020) and ocular misalignment (p = 0.037) were associated with visual impairment on multivariate analysis. The spectacle correction coverage was 11% and only 8% of the students had prior ophthalmic care utilization. Ignorance of ocular morbidity and perceived inaccessibility of eye care were cited by parents/guardians as reasons for poor utilization of eye-care services. CONCLUSION: A high prevalence of visual impairment was found among the hearing impaired students; uncorrected refractive error and refractive amblyopia were the most prevalent causes. The level of prior ophthalmic service utilization was found to be low. It was recommended that ophthalmic services especially refractive services should be made available in schools for the hearing impaired.

RESUMEN

AIM: To gauge the prevalence of hearing loss in school children in Bishkek, Kyrgyzstan, and refer pupils with positive results for further diagnostic testing. BACKGROUND: According to WHO data, hearing disorders are common in school-age children. Screening for hearing loss is an important preventative tool, helping to avoid further complications. Expenditure that supports early child development can reduce future outlay on health care and social services; it can eliminate disability problems, education deficits, and social maladaptation in later adult life. METHODS: Pure-tone air-conduction hearing thresholds were obtained at 0.5-8 kHz. The results of the hearing screening examination were regarded as positive if pure-tone thresholds were higher than 20 dB HL in one or both ears at one or more of the test frequencies. Data were also obtained from follow-up visits of children who failed the initial screening. FINDINGS: This study included 452 children aged 7-13 years old. Based on audiograms, screening showed that 123 (27.2%) of the children had hearing impairment. The study has important implications for clinical practice and health policy. There is a need for systematic monitoring of hearing status among children of this age, and parents and educators need to be made aware of the significance of hearing loss.

RESUMEN

Left ventricular noncompaction (LVNC) is a hereditary cardiomyopathy and is associated with high morbidity and mortality. However, the role and significance of school screening for LVNC have not been fully elucidated. In this multicenter, retrospective cohort study, a total of 105 children with LVNC were included from 2000 to 2017. At the initial presentation, 44 patients (41.9%) were diagnosed by school screening. One (1.0%) patient underwent heart transplantation and four (3.8%) patients died during the study. Electrocardiogram data showed a high prevalence of fragmented QRS (33.4%) and J wave (15.7%). Treatments were needed in eight (18.2%) patients who were detected by school screening. The multivariable proportional hazards model showed T-wave abnormality on electrocardiogram in first graders was independent risk factors for major adverse cardiac events (odds ratio 4.94, p value = 0.0007). Moreover, dilation of the left atrium on chest X-ray and low ejection fraction on echocardiogram at the initial treatment were independent risk factors for treatment (odds ratio 1.7 × 107 and 22.3, p = 0.0362 and 0.0028, respectively). This study is the first report focusing on school screening in a large pediatric cohort with LVNC. With the use of abnormalities in electrocardiogram, school screening may be a good detector of and predictor for LVNC.

RESUMEN

Purpose: To explore the possibility of vitamin A deficiency (VAD) detection through School Sight Program (SSP) in a tribal district of Odisha, India. Methods: In a cross-sectional observational study, we tracked school children with ocular signs/symptoms of VAD to their villages. The ophthalmologist examined their under-5 siblings and other under-5 children in the village. Information pertaining to family belief and practices of food, water, sanitation, and the socioeconomic status of the family were collected. Results: The ocular features of VAD were detected in 207 of 4801 (4.3%) examined children. This included 70 children (mean age 11 ± 2.6 years) detected in the school, 22 siblings (mean age 3.2 ± 1.2 years) of these children detected at their home, and 115 children (mean age 3 ± 1.5 years) detected in their habitat. The average family size was 5.8 ± 2.02 and the birth order of the child with VAD was 2.3 ± 1.25. Most parents were farmer, living in asbestos-roofed house, depended on public underground water, and practiced open-air defecation. The distribution of VAD in 207 children was conjunctival xerosis (X1A = 207; 100% of VAD and 4.3% of all children), Bitot's spot (X1B = 169; 81.6% of VAD and 3.5% of all children), corneal scar (XS = 3; 1.4% of VAD and 0.06% of all children), and night blindness (XN = 35; 16.9% of VAD and 0.72% of all children). Conclusion: An opportunistic screening for detection of VAD through a SSP could be cost-effective and complement the existing strategy.
