Abstract: Stereopsis detection has experienced the continuous evolution of depth gauge, pattern stereopsis and random dot examination. The traditional stereovision examination methods are represented by Titmus and synoptophore, but there are many problems such as high requirements for examination equipment and subjective factors. The combination of 3D display, mobile phone software and other technologies can reduce the examination requirements, increase patient compliance, and obtain a wide range of disparity and accurate examination values. Stereoscopic vision training has been developed from traditional synoptophore training to visual perception training and mixed training. Recently, virtual reality (VR) and other technologies have also been applied to visual perception training to improve patient compliance and obtain better training effects. There are many methods for detecting and training stereovision function, each of which has its own advantages and disadvantages. Clinicians should choose the appropriate method for patients and combine various methods to evaluate and train stereovision function of patients in a comprehensive way.
