“…Using the manufacturer's referral criteria, we found reasonably good sensitivity and specificity with both recent software updates, as did Silbert and Matta 9 using the original software and higher than did Arnold and colleagues. 6 While a specificity in the low 70% range may be not be adequate for some screening situations, adjustments in referral criteria for the Spot may result in continued improvements in the future.…”

“…2 Although the Spot Vision Screener 3 (Welch Allyn, Skaneateles Falls, NY) is marketed to schools, 4,5 there are few published reports evaluating its effectiveness. 6-8 Silbert and Matta 9 recently reported their experience using the Spot with the original software (v. 1.0.3), noting that performance would be expected to improve with future criteria modifications and improved software. The purpose of this study was to evaluate the newer software versions of the Spot (v. 1.1.51 and v. 2.0.16) in detecting amblyopia risk factors according to the 2013 American Association of Pediatric Ophthalmology and Strabismus Vision Screening Committee guidelines for automated vision screeners.…”

Background The purpose of this study was to evaluate the updated Spot Vision Screener (PediaVision, Welch Allyn, Skaneateles Falls, NY) in detecting amblyopia risk factors using the 2013 guidelines of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS). Methods In this prospective study, patients seen from June 2012 to November 2013 were tested with the Spot prior to examination by a pediatric ophthalmologist who was masked to test results. The following data were analyzed: age, subject testability, examination findings, and systemic and ocular pathology. Children were divided into three age groups to determine gold standard results according to the AAPOS guidelines. Results A total of 444 children (average age, 72 months) were included. Compared to the ophthalmologist's examination, the Spot sensitivity was 87.7% and the specificity was 75.9% in detecting amblyopia risk factors. There were no significant differences in sensitivity between the age groups, although the positive predictive value improved in the older age groups. Conclusions In our study cohort, the Spot provided good specificity and sensitivity in detecting amblyopia risk factors according 2013 AAPOS criteria, with minor improvements with updated versions.

Purpose Amblyopia is a permanent visual impairment developed in early childhood. Recently, instrument‐based photoscreeners have been widely used for vision screening to detect amblyopia risk factors, which is key for the prevention and treatment of amblyopia. This meta‐analysis aims to evaluate the diagnostic test accuracy of Spot and Plusoptix photoscreeners in detecting risk factors for amblyopia in children. Methods An electronic literature search was performed in October 2018 using the MEDLINE, Embase, and Web of Science databases. Twenty‐one publications with a total of 5022 subjects were included. Subjects given a comprehensive examination were considered to have amblyopia or amblyogenic risk factors based on the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) referral criteria guidelines. Results The overall sensitivity for Spot and Plusoptix was 87.7% and 89.4%, respectively (p = 0.38); the specificity was 78.0% and 89.9%, respectively (p = 0.90). For subjects under 7 years old (preschool children), the overall sensitivity for Spot and Plusoptix was 91.7% and 90.2%, respectively (p = 0.81); the specificity was 82.6% and 93.0%, respectively (p = 0.46). Conclusion Both Spot and Plusoptix photoscreeners demonstrated good sensitivity and specificity in detecting amblyopia risk factors in children, especially at preschool ages. There was no significant difference in diagnostic test accuracy between them.

“…Atualmente encontra-se cientificamente comprovado que as crianças amblíopes têm a sua performance prejudicada a nível escolar, quer no que diz respeito aos hábitos de leitura, quer na capacidade de cálculo, pelo deficiente reconhecimento de letras e números. 7,8 Do ponto de vista fisiológico, a explicação assenta no hemi-córtex occipital que, ao receber imagens degradadas pela perceção sensorial alterada de um olho amblíope, não desenvolve o seu potencial na totalidade, uma vez que vai eliminar uma imagem de uma das vias visuais, a imagem escolhida como errónea. O erro refrativo (miopia, hipermetropia, astigmatismo), a causa mais comum de ambliopia na infância, é menos percetível para os pais do que o estrabismo.…”

Introduction: Amblyopia is the leading cause of monocular vision loss in paediatric age groups. It is a preventable and reversible condition when detected and treated early. Refractive error is the most common cause of childhood amblyopia, and cannot be adequately detected by standard vision assessment in primary care. The use of photoscreening devices has a high positive predictive value (73%). Methods: A prospective analysis was performed of amblyopic factors in children aged 12 months to 6 years in an urban area of the central region of Portugal, using photoscreening equipment (Plusoptix® S04). Results: A total of 409 preschool children were screened. Of these, 49 (12%) presented referral criteria and 15 were being followed in the ophthalmology clinic. Of the 27 children attending the post-screening consultation, 19 (70.4%) were diagnosed: astigmatism (eight), anisoastigmatism (five), anisohypermetropia (four), myopia (one) and anisomyopia (one). This screening method had a positive predictive value of 70%. During the 13.8±6.8 months of follow-up visual acuity improved in all children with corrective lenses. Discussion: None of the children showed symptoms suggestive of visual disturbance, explained by the fact that signs of diminished visual acuity are often unnoticed. The main risk factor for amblyopia was astig-Introdução: A ambliopia é a principal causa de perda de visão monocular em idade pediátrica, uma condição prevenível e reversível quando detetada e tratada atempadamente. O erro refrativo é a causa mais comum de ambliopia na infância e a sua deteção não se pode limitar à avaliação tradicional da visão feita nos cuidados primários. A aplicação de dispositivos de foto-rastreio apresenta elevado valor preditivo positivo (73%). Métodos: Análise prospetiva de fatores ambliogénicos em crianças com idades compreendidas entre os 12 meses e os 6 anos numa área urbana da região centro de Portugal, recorrendo a equipamento de foto-rastreio (Plusoptix®S04). Resultados: Foram rastreadas 409 crianças em idade pré-escolar. Destas, 49 (12%) apresentavam critérios para referenciação, 15 já eram seguidas em consulta de oftalmologia. Das 27 crianças que compareceram à consulta 19 (70,4%) foram diagnosticadas, sendo o diagnóstico de astigmatismo em oito, aniso-astigmatismo cinco, aniso-hipermetropia em quatro, miopia em uma e aniso-miopia em uma. Este método de rastreio demonstrou ter um valor preditivo positivo de 70%. Durante os 13,8 ± 6,8 meses de seguimento, todas as crianças melhoraram a acuidade visual com correção ótica. Discussão: Nenhuma criança mostrava sintomatologia que sugerisse perturbação da visão, o que se explica pelo facto dos sinais de diminuição da acuidade visual nestas idades passarem frequentemente despercebidos. O principal fator de risco para ambliopia foi o astigmatismo. A deteção de erros refrativos em idade pré-escolar não se pode limitar à observação tradicional em cuidados de saúde primários. O foto-rastreio demonstrou ser um excelente método de rastreio, respeitando todos os princípios est...
