Supranuclear eye movements and nystagmus in children: a review of the literature and guide to clinical examination, interpretation of findings and age appropriate norms

Abstract

Abnormal eye movements in children present a significant challenge to Ophthalmologists and other healthcare professionals. Similarly, examination of supra-nuclear eye movements in children and interpretation of any resulting clinical signs can seem very complex. A structured assessment is often lacking although in many cases, simple clinical observations, combined with a basic understanding of the underlying neurology, can hold the key to clinical diagnosis. As the range of underlying diagnoses for children with abnormal eye movements is broad, recognising clinical patterns and understanding their neurological basis is also imperative for ongoing management. Here we present a review and best practice guide for a structured, methodical clinical examination of supranuclear eye movements in children, a guide to clinical interpretation and age-appropriate norms. We also detail the more common specific clinical findings and how they should be interpreted and used to guide further management. In summary, this review will encourage clinicians to combine a structured assessment and a logical interpretation of the resulting clinical signs, in order to recognise patterns of presentation and avoid unnecessary investigations and protracted delays in diagnosis and clinical care.
