“…It is encouraging that screening for congenital eye disorders occurs in most of the countries described. This has been shown to be very cost-effective ( van den Akker-van Marle et al 2015 ). Furthermore, some form of VA testing is being undertaken during childhood.…”

Purpose: To describe and compare vision screening programmes and identify variance in number and type of tests used, timing of screening, personnel involved, monitoring and funding to be used as data for optimising, disinvesting or implementing future screening programmes. Methods: A questionnaire consisting of nine domains: demography & epidemiology, administration & general background, existing screening, coverage & attendance, tests, follow-up & diagnosis, treatment, cost & benefit and adverse effects was completed by Country Representatives (CRs) recruited from 47 countries. Results: The questionnaire was sufficiently completed for 46 Countries: 42 European countries, China, India, Malawi and Rwanda. Variation of provision was found in; age of screening (0–17 years), tests included (23), types of visual acuity (VA) test used (35 different optotypes), personnel (13), number of screens per child (median 5, range 1–32), and times VA tested (median 3, range 1–30). Infant screening is offered in all countries, whereas childhood vision screening is offered at least once in all countries, but not all regions of each country. All 46 countries provide vision screening between the ages of 3–7 years. Data on screening outcomes for quality assurance was not available from most countries; complete evaluation data was available in 2% of countries, partial data from 43%. Conclusion: Vision screening is highly variable. Some form of VA testing is being undertaken during childhood. Data collection and sharing should be improved to facilitate comparison and to be able to optimise vision screening programmes between regions and countries.

“…The algorithm included newborns of ≤ 30 WOP and ≤ 1,500 g at birth and a net weight gain of ≤ 650 g during the 1st month of postnatal life ( 68 ). The Netherlands Retinopathy of Prematurity Study Model (NEDROP) studied several ROP screening strategies and concluded that the strategy that most efficiently diagnosed ROP was the one including newborns of ≤ 30 WOP and ≤ 1,250 g of birth weight and neonates of gestational age between 30–32 WOP and 1,250–1,500 g of birth weight, with at least one risk factor (treatment with oxygen or corticosteroids, sepsis, necrotizing enterocolitis, or heart disease) ( 73 ).…”

Importance: Vascular delay that occurs early in the development of retinopathy of prematurity (ROP) is a risk factor that can be compensated by ensuring a good rate of retinal vascularization to avoid ROP that requires treatment. Background: The objective of the present study was to determine the association between ROP that requires treatment and risk factors such as the extent of the temporal avascular area of the retina and the number of days of mechanical ventilation (MV). Design: Observational retrospective case-control study. Participants: Two hundred and twenty-eight premature newborns included in the screening protocol for retinopathy of prematurity. Methods: Subjects underwent retinal examination in the 4 and 6th postnatal weeks. Main Outcome Measures : The temporal avascular area was measured in disc diameters (DD), while the MV time was measured in days of treatment. Results: Patients with a longer MV time had a higher risk of treatment (R 2 : 24.7, p < 0.0001; increase in risk of 8.1% for each additional day), as did those who showed greater avascular area (R 2 : 24.7, p < 0.0001; increase in risk of 111% for each additional DD). An online calculator system and a table are presented for calculating the risk of ROP requiring treatment as a function of these two risk factors. Conclusions and Relevance: The temporal avascular area of the retina and MV time must be taken into account in the first examination of the newborn to predict the need for ROP treatment.

“…These varied risk factors can include differences in BW or gestational age, history of intraventricular hemorrhage, impaired lung function, sepsis, postnatal glucocorticoids, necrotizing enterocolitis, and use of cardiotonic agents. 22,23 Several systems for identifying at-risk neonates or pregnant women at greater risk for delivering children with ROP have been developed in urban and rural health centers across the globe. In 2008, the Narayana Nethralaya Postgraduate Institute of Ophthalmology (NNPIO) in Bangalore, India developed a mobile screening program that fuses the knowledge base and skill set of pediatric retina specialists with the accessibility of nonphysician field teams to identify and treat infants at risk of ROP.…”

BackgroundThe 10 Essential Public Health Services Model Challenges to Retinopathy of Prematurity (ROP) Screening and the Need for a Model to Evaluate Screening Methods ROP is one the leading causes of preventable childhood blindness in the world. 1 In 2010, an estimate of 184,700 preterm infants worldwide developed some degree of ROP, and of these, 53,800 developed visually impairing severe disease (Blencowe et al 2010). Improving the efficiency and efficacy of ROP screening processes, education, and awareness amongst providers and families are the most important tools to reduce visual morbidity over a child's lifetime. Countries all around the world have designed methods for making screening, education, and awareness affordable, efficient, and accessible. However, there is great variability among these screening programs based on regional trends in disease severity and variable access to infrastructure for screening, treatment, and neonatal intensive care. This programmatic review seeks to examine efforts in establishing ROP screening programs through the lens of a public health model to identify strengths of these programs, as well as areas for improvement. By collecting data and evaluating these programs through an objective model, public health experts, health care providers, and policymakers can get an overview of previous work in capacity building and ROP screening program development. With this information, they can use this model to identify the successes and challenges to implement screening programs that are tailored to the needs of a region. Model SelectionIn the process of selecting a model to evaluate the various screening programs, the Social Determinants of Health (SDH) model of 2020 was considered for evaluation. 2 This dynamic model addresses contributing factors of health inequities, though it limits evaluation in several areas which are a core part of ROP screening programs. The SDH model does not address material circumstances, behavior, biological, and psychosocial factors that contribute to ROP incidence and prevalence. In addition, it does not address the role of research in evaluating areas for future work. The Ten Essential Public Health Services (TEPHS) model, however, may address some of the potential limitations of the SDH model and includes social determinants of health inequities. 3 Therefore, after further consideration and evaluation, the Ten Essential Public Health Services Model was chosen for our analysis.
