Hello. New to the Forum but not the NNetwork. Our 3 year old son has congenital idiopathic nystagmus (vertical see-saw) and just this week was diagnoised with ASD. We would be extremely interested in this research. The information we learnt from the Nystagmus Open Day last year made us realise that other very young children displayed similar behaviour as our son and so we attributed much unusual behaviour down to vision. i.e. lying on the ground playing with trains/cars, being scared at sudden noise, not always making eye contact when engaged in play and talking to someone. However, despite being a very social, friendly little boy, there is a lack of understanding language, as well as S&L delay (jargon and echolalia). What we are concerned with, is that has his visual behaviour been misinterpreted? Much of this behaviour is also displayed by children with ASD. Has enough time elapsed to be absolutely sure? Or might is be some other diagnosis? We have lost confidence in 'professionals' (Consultant Paediatrician) as originally they interpreted our son's abnormal head posture to behaviour and we knew conclusively this to be due to nystagmus, as did his Consultant Ophthalmologist. We would be extremely grateful for any up-to-date research or similar experiences.
