“…77 Although low doctor density and poor health-care coverage might make expanded general paediatric screening unfeasible, charity-funded or government-funded subspecialty training programmes to supply ocular oncologists for unserved and underserved countries are effective. 78 For instance, an outreach project in Bangladesh yielded a 98% response rate and identified 5% of patients with ocular morbidities, 79 while retinoblastoma awareness campaigns in Honduras have reduced late presentation from 73% to 35%. 80 It is important to help parents to identify red-flag symptoms and encourage their use of patient support services.…”

Background Despite advancements in globe-preserving treatments, improvements in retinoblastoma outcomes are inconsistent across income levels and geographical locations. We aimed to investigate trends in global retinoblastoma survival and globe preservation during the past 40 years. We also examined associated socioeconomic and health-care factors and global survival disparity. MethodsWe did a systematic review and meta-analysis by screening articles in any language in nine databases (PubMed, Embase, ScienceDirect, Web of Science, OpenGrey, Global Burden of Disease, Global Health Data Exchange, Global Index Medicus, and International Agency for the Prevention of Blindness) published between Jan 1, 1981, and Oct 8, 2021. We screened for articles that described retinoblastoma overall survival or globe salvage, or both. All reported studies were subsequently stratified into four periods: 1980-89, 1990-99, 2000-09, and 2010-20. Indicators on socioeconomic and health-care factors were extracted from the World Bank and WHO. Ophthalmology-related indicators were further parsed from the International Agency for the Prevention of Blindness. Between-study heterogeneities by income level were assessed by mixed-effect meta-analysis. Associations of retinoblastoma outcome with socioeconomic and health-care factors and factors for survival prediction were investigated by multivariable linear regressions. This study is registered with PROSPERO, number CRD42020221556. Findings Our search identified 14 621 articles, of which 314 studies were included for analysis after screening, including 38 130 patients from 80 regions globally presenting during 1980-2020. 255 articles were entered for timetrend meta-analysis, covering 29 106 patients from 73 countries. Both overall survival (from 79% [95% CI 74-84] to 88% [83-93]; p=0•017) and globe salvage rate (from 22% [14-32] to 44% [36-52]; p=0•0003) improved significantly over the four decades. Wide disparities were observed between higher-income and lower-income countries. Overall survival, globe salvage, and globe salvage for advanced intraocular disease correlated positively with income level. Higher overall survival was associated with lower Gini index (p=0•0001) and with populations that had smaller percentages living in rural areas (p=0•0005). Higher globe salvage was associated with better health-care financing and accessibility (p=0•030). Overall survival (p=0•0024) and globe salvage (p=0•022) were both associated positively with education level. Survival gaps were observed in sub-Saharan Africa and southeast and southwest Asia.Interpretation Retinoblastoma treatment outcomes have improved globally over the past four decades but large disparities persist between higher-income and lower-income countries, with some areas having major survival gaps. Targeted health-care policy making with increased health-care financing and accessibility are needed in low-income and lower-middle-income countries to improve retinoblastoma outcomes worldwide.Funding Health and Medical Research Fund (H...

“…A community-based study on epidemiology of childhood blindness in Bangladesh in 2019 found a prevalence rate of 6.3 per 10,000 children in Sirajganj and another study found a prevalence of 6 per 10,00 children. However, the prevalence of ocular morbidity was 5.63% [23,24]. Our study did not perform visual acuity tests in the school children.…”

Aims: There is scarcity of research on the health and disease status of primary school children in Bangladesh. This study aimed at assessing prevalence of medical diseases and surgical conditions among rural primary school children. Materials and Methods: It was a cross sectional study conducted in 2018 on 2 public and 2 private primary school children in Bakila and Gogra village of Chandpur district. History of immunization, deworming, major current or previous illness, allergy, trauma, surgery and drug history were recorded. Anthropometric measurements, milestones of development, body build and nutritional status; and other general and systemic examinations were carried out. Comparison was made between the public and private primary school students. Results: 227 primary school children (99 public school students and 128 private school students), were evaluated. Median age was 7 years and male to female ratio was 1.39:1. At least one medical disease or surgical condition was present in 146 (64.3%) students. Medical disease was present in 114 (50.2%) and surgical condition was present in 40 (17.6%) children. About 96.48% children completed immunization and 76.65% children were having regular deworming. Overall, 19.38% children were underweighted and 24.23% children were stunted. Bronchial asthma was the most common medical disease (11.89%), followed by rhinitis (8.37%) and food allergy (5.73%). Dental caries was the most common surgical condition, followed by tonsillitis (4.41%) and chronic suppurative otitis media (CSOM), 2.64%. Conclusion: A diverse medical diseases and surgical conditions were prevalent among primary school children and most of these are preventable. These did not vary significantly between public and private schools.

Background There are limited systematic reviews on the prevalence of uncorrected refractive errors in children. We aimed to summarize the prevalence and causes of pediatric uncorrected refractive error (URE) from studies in the Global Burden of Disease (GBD) sub-regions. Methods The pooled analysis used the individual participant data (ages less than 20 years old) from population-based studies around the world by regions. URE was defined as presenting VA < 6/18 and improving to ≥ 6/18 or ≥1 line on using a pinhole in either eye, with main causes of myopia, hyperopia or astigmatism. Each study provided data on any URE, myopia, hyperopia or astigmatism by age, gender, and ethnicity. Prevalence rates were directly age and gender standardized to the 2020 world population with all age groups. Estimates were calculated by study and sub-regions after pooling. Summary estimates included studies in which URE was assessed from a pinhole-corrected refraction in the better eye. Results The combined pooled data contained 302,513,219 patients including 8 963 URE cases individuals from 57 studies. Prevalence varied by age and GBD sub-regions and differed by gender. The age- and region-standardized prevalence of URE was 3.41 per 1000 (CI, 1.53~7.62) in Western Pacific region (12 studies), 2.26 per 1000 (CI, 0.85~6.01) in South-East Asia region (14 studies), 5.85 per 1000 (CI, 3.75~9.13) in Americans (11 studies) and 4.40 per 1000 (CI, 3.0~6.45) in Eastern Mediterranean region (13 studies). On the basis of these data, myopia was the first-leading cause in female children with 12~17 age group, with the prevalence rate 18.2 per 1000 (CI, 11.52~23.61). Astigmatism was detected in 27.2 per 1000 male children with 6~11 age group (CI: 19.12–30.68). Conclusions Prevalence of URE available data within these sub-regions are widely disparate. Myopia and astigmatism in young age children continue as the leading cause of URE worldwide. Providing appropriate refractive correction to those individuals whose vision can be improved is an important public health endeavor with implications for safety and quality of life.
