  • infantile
  • intermittent
  • accommodative
  • non accommodative



Dissociated vertical deviation



Very little is known about the pathogenesis of common strabismus and, although there is significant evidence for a genetic basis, no disease or susceptibility genes have been identified.

We are commencing research in collaboration with Department of Ophthalmology and the General Clinical Research Center at Boston Children's Hospital to identify disease and susceptibility genes for these forms of strabismus and hope this work will lead to identification of individuals at risk, improve our ability to detect and prevent amblyopia (reduced vision in a healthy eye) and loss of binocular vision, and provide insight into the pathogenesis of these common disorders.
