Deaf-blindness is a very low incidence disability and within this very small group of children there is great variability. Many children who are deaf-blind have some usable vision and/or hearing. The majority of children who are deaf-blind also have additional physical, medical and/or cognitive problems. Children are considered to be deaf-blind when the combination of their hearing and vision loss causes such severe communication and other developmental and educational needs that they require significant and unique adaptations in their educational programs.
