The study was performed on a group of ten children (five males and five females aged 11.3±1.6 years) with normal binocular vision, and revealed a visual phenomenon consisting of stochastic disappearanceof part of a visual scene caused by auditory stimulation.Results: Indeed, during the Maddox test, brief sounds induced transient visual scotomas (VSs) in the visual field of the eye in front of where the Maddox rod was placed. We found a significant correlation between the modification of binocular vision and VS occurrence. No significant difference was detected in the percentage or location of VS occurrence between the right and left eye using the Maddox rod test orbetween sound frequencies.Conclusion: The results indicate a specific role of the oculomotor system in audiovisual integration in children. This convenient protocol may also have significant interest for clinical investigations of developmental pathologies where relationships between vision and hearing are specifically affected.Keywords: multisensory integration, binocular vision, audiovisual development, visual losses, ocular proprioceptionQuercia PPozzo TMarino AGuillemant ALCappe CGueugneau NDove Medical Pressarticlemultisensory integrationbinocular visionaudiovisual developmentvisual lossesocular proprioceptionOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 1137-1145 (2019)
