Vestibular ocular reflex recording method for autism spectrum disorder children

Abstract

The invention discloses a vestibular ocular reflex recording method for autism spectrum disorder children. The vestibular ocular reflex recording method is characterized in that a first 980nm laser sensor and a second 980nm laser sensor are arranged at the left front part and the right front part of the left side and the right side of a glasses support respectively; a laser beam emitted by the second 980nm laser sensor is incident to the left eye through a beam expanding lens, and a 10-degree angle is formed between the light and an eyeball; a laser beam emitted by the first 980nm laser sensor enters the right eye through the beam expanding lens, and an angle of 10 degrees is formed between the light and an eyeball; and the first 980nm laser sensor is used for measuring the vestibular ocular movement of the right eyeball. Vestibular ocular movement amplitude, frequency and phase of eyeballs are determined through a function relation between eyeball displacement components in the light propagation direction and eyeball displacement, so that vestibular ocular reflex of the autism spectrum disorder children is rapidly recorded. According to the method, the vestibular ocular reflex of the autism spectrum disorder children can be rapidly recorded through a set of glasses type laser sensors, and the vestibular ocular reflex detection efficiency and accuracy of the autism spectrum disorder children are improved.

Description

technical field [0001] The invention relates to the technical field related to autism, in particular to a method for recording vestibular eye movement reflex of autistic children. Background technique [0002] Autism Spectrum Disorder (ASD) is a type of neurodevelopmental disorder in children characterized by social interaction and communication impairment, narrow interests and stereotyped behavior. In recent years, the global incidence of ASD has increased significantly, but the etiology of autism is still unclear, coupled with the serious shortage of diagnosis and intervention resources, autism has evolved into a major global public health problem. Children with autism usually show that they like to spin or run in circles without getting dizzy or tired; poor coordination of hands when eating, acting, drawing, and beating drums; running out, climbing up and down, and not listening to dissuasion; Behaviors such as slurring words and repeating the same sentence are all relat...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method for recording vestibular eye movement reflex in children with autism, to solve the problem of recording eye movement data through video in the current market proposed by the above-mentioned background technology, and convert the eyeball rotation angle with the method of image processing, Its advantage is that the video is completely non-invasive, but in this method, the subject's head must be fixed at a certain position, and it must be relatively stationary with the camera position, so the experiment of making the head free cannot be done; when squinting for various reasons eye movement data cannot be recorded
