Abnormal eye movement can indicate the possibility of central nervous system diseases. Abnormal eye movement is found during examination. It is recommended to go to neurology department to rule out nervous system diseases. The most important significance of eye movement examination in clinic is the diagnosis and analysis of a series of abnormal fixation and saccade movement related to reading. Research shows that patients with dyslexia and slow reading speed will have small frequency and continuous re gaze and return movement at the same time. Although the relationship between reading and functional eye movement still needs in-depth research, scientific researchers and clinical workers have always stressed that there is a certain correlation between eye movement and reading, so it is an indisputable fact that patients with dyslexia show abnormal eye movement, which urges us to evaluate eye movement.

At present, there are two views on the relationship between eye movement and monthly reading: first, eye movement disorder can lead to low reading ability. The study found that unskilled readers have longer fixation time and return time than normal readers; Second, those who cause dyslexia and lack of language ability will have random unskilled eye movements. It can be seen that dyslexia itself also leads to wrong and uncoordinated eye movements. Clinical work found that in some cases, eye gaze and saccade ability may be the main factors affecting children's fast and comfortable reading and understanding, while in other cases, insufficient eye movement ability may be a manifestation of low reading ability. Another important factor is the interaction between eye movement and higher cognitive processes, including attention, memory and the application of visual information. Treatment and rehabilitation training of eye movement disorder can improve the concentration of attention.

Eye movement disorder usually does not exist alone, sometimes accompanied by abnormalities of adjustment, binocular visual function and visual perception function. Therefore, the treatment of eye movement deficiency needs to treat other disorders at the same time.
