Blindism

Set of behaviors in visually impaired children Blindisms, also known as restricted or repetitive behavior (RRB) in visually impaired children, and stereotyped behaviors in blind children are a set of stereotypies (stereotyped, habitual and characteristic movements) in visually impaired children. These appear most often in those who are congenitally blind. Frequent movements include body rocking, repetitive handling of objects, hand and finger movements, eye poking, pressing and rubbing. Causes are not well understood, and treatment outcomes tend to be highly variable but generally positive. Symptoms and presentation RRBs in visually impaired children are categorised into mannerisms and motor stereotypes. Mannerisms include eye poking, pressing and rubbing, gazing at lights and staring. Motor stereotypes include repetitive head/body rocking, thumb sucking, jumping, swirling, and repetitive hand/finger movements. Blindism behaviors overlap with stereotypies observed in autistic people, and as some diagnostic criteria of autism depend on vision, it is particularly difficult to diagnose autism among the visually impaired, often based on a subjective clinical impression.
