“…Since the first reported government funded vision screening program more than 100 years ago, implementation of vision screening evolved from chart-based to instrument-based approach 15, 67. In this review, 44% of the countries used the single-test design of visual acuity testing only despite its limitation in detecting other types of vision disorders among children apart from reduced vision.…”

“…Subsequently, the nature of mass screening programs as high budget items attracts considerable debate 10, 11. Mass pediatric vision screening had been widely reviewed but has evaded concise analysis due to divisive opinions regarding operational efficiencies and benefits despite collective agreement on its importance 1, 7, 12, 13, 14, 15. Specifically, studies on pediatric vision screening lacked generalizable conclusions because of inconsistencies in their program objectives and implementations 7 …”

PurposeIncorporating mass pediatric vision screening programs as part of a national agenda can be challenging. This review assessed the implementation strategy of the existing pediatric vision screening program.MethodsA search was performed on PubMed, EBSCO host MEDLINE Complete, and Scopus databases encompassing the past ten years for mass pediatric screening practice patterns that met the selection criteria regarding their objectives and implementation. Results were analyzed from 18 countries across five continents.ResultsEight countries (44%) offered screening for distance visual acuity only, where the majority of the countries (88%) used either Snellen or Tumbling E chart. High-income countries initiated screening earlier and applied a more comprehensive approach, targeting conditions other than reduced vision only, compared with middle-income countries. Chart-based testing was most commonly performed, with only three countries incorporating an instrument-based approach. Lack of eyecare and healthcare practitioners frequently necessitated the involvement of non-eyecare personnel (94%) as a vision screener including parent, trained staff, and nurse.ConclusionsImplementation of a vision screening program was diverse within countries preceded by limited resources issues. Lack of professional eyecare practitioners implied the need to engage a lay screener. The limitation of existing tests to detect a broader range of visual problems at affordable cost advocated the urgent need for the development of an inexpensive and comprehensive screening tool.

“…error. 10,11 This study is concerned with the measurement accuracy and precision of four such techniques that operate on different working principles and routinely used in clinical settings for the purposes mentioned above (Table 1). These include the goldstandard retinoscopy and three automated refraction techniques, first, based on a proprietary rotary prism technology (RM-8900 table-top autorefractor; Topcon, Tokyo, Japan), second, based on eccentric infrared photorefraction (Spot Vision Screener; Welch Allyn, Skaneateles Falls, NY; Photoscreener) 12,13 and third, based on wavefront aberrometry (E-see; Aurolab, Madurai, India) 14,15 (see Table 1).…”

“…Of these, the refractive error estimates obtained using retinoscopy, tabletop autorefractor, and E-see are intended to be used as starting points for subjective refraction to finalize the patient's sphero-cylindrical prescription, whereas those obtained using the Photoscreener are intended to screen for patients with UREs. 11,16,17 It is evident from Table 1 that each design of autorefractor has certain advantages over the others and may become the choice of measurement technique in specific settings or for specific populations. For instance, the Photoscreener may be useful for obtaining simultaneous estimates of both eyes refractive error and the near-triad rapidly in infants and children where cooperation may be limited (see Table 1).…”

“…Some earlier reviews examined technologies for a part of a vision assessment battery. O’Hara and O’Hara 26 Nottingham et al 14 and Kaseem 15 examined the autorefractors, photoscreeners devices or optotype software. Kaseem et al 15 discussed a paediatric vision scanner device that uses the retinal birefringence technique.…”

Technologies supporting vision screening: a protocol for a scoping review

et al. 2021

Introduction Vision problems affect academic performance, social and mental health. Most traditional vision screening methods rely on human expert assessments based on a set of vision tests. As technology advances, new instruments and computerised tools are available for complementing vision screening. The scoping review based on this protocol aims to investigate current technologies for vision screening, what vision tests can be complemented by technologies, and how these can support vision screening by providing measurements. Methods and analysis The planned review will utilise the PRISMA extension for Scoping Reviews (PRISMA-ScR) tool. Electronic search will be performed in databases, including Web of Science, MEDLINE (Ovid), Scopus, Engineering Village, Cochrane and Embase. We will perform a systematic search in selected reference databases without the limitation on publications dates, or country of studies. Reference management software, like EndNote and DistillerSR, will be used to remove duplicate entries. Two authors will independently analyse the studies for inclusion eligibility. Conflicts will be resolved by discussion. We will extract the types of technologies, types of vision tests they complement and the measurements for the included studies. Overall findings will be synthesised by thematic analysis and mapping to the logic model. Ethics and dissemination Ethical approval is not required for this review, as it will only summarise existing published data. We will publish the findings in an open access, peer-reviewed journal. We expect that the review results will be useful for vision screening experts, developers, researchers, and policymakers.

Instrument-based pediatric vision screening

Abstract: Instrument-based vision screening in the young child is an accepted method of screening for amblyopia. Innovations in instrumentation will continue to improve its implementation.
