The Synoptophore is a diagnostic and therapeutic device used to evaluate and treat binocular vision disorders such as strabismus (squint). It measures eye alignment, fusion, and depth perception while also providing vision therapy exercises to improve eye coordination. This equipment is commonly used in ophthalmology clinics and orthoptic departments. It is typically made of a metal and high-grade plastic body with optical tubes, mirrors, adjustable arms, illumination system, and electronic control components.
