Abstrakt:	Background: The Spot Vision Screener (SVS) is designed to detect significant ametropia, anisometropia, and strabismus in non-dilated eyes. This study evaluates the efficacy of the SVS in paediatric visual screening. Patients and Methods: All children screened during the paediatric visual screening day in Lausanne in 2016 were evaluated with the SVS, conventional monocular autorefractors, and clinical orthoptic examination. Recommendations for a further eye examination of the SVS were compared with those issued from traditional clinical screenings (monocular refraction and orthoptic examination). Results: One hundred and sixty-eight consecutive children were included. The median age was 3.9 years. The SVS median spherical equivalent (SE) was + 0.25 D OU and it detected seven cases of (4.2%) anisometropia (SE difference ≥ 1 D). The conventional monocular autorefractor median SE was - 0.13 D OU and 20 cases of anisometropia (11.9%) were detected. Refraction could not be measured in 1.2% of patients with SVS versus 17.2% with monocular refractors. The SVS screened two manifest strabismus cases against five manifest and > 100 latent strabismus with orthoptic examination. As expected, the SVS was unable to assess reactions to monocular occlusion, visual acuity, and stereovision as well as to detect ocular motility disorders without strabismus in the primary position, and missed two cases of abnormal Brückner reflexes. Overall, the SVS identified 66 suspect patients (39.3%) against 102 (60.7%) after complete clinical examination. Conclusions: The SVS can be a useful objective screening tool for non-ophthalmologists. However, because it fails to detect ocular motility troubles, organic visual acuity loss, or to assess the visual potential, it should only be used in association with a clinical examination, even in routine screening procedures. Competing Interests: The authors have no conflict of interest to declare. (Georg Thieme Verlag KG Stuttgart · New York.)
