One of the main surgical procedures for nystagmus is the removal of proprioceptors, so what are proprioceptors? Why can removal of proprioceptors improve nystagmus? The proprioceptors are receptors located in muscles, tendons and joints that sense changes in body movement and position in space and provide information to the center. When the eye moves, the mechanical stretching of the muscle and tendon becomes a suitable stimulus for the proprioceptors and transmits the degree of stretching to the center. It may be due to the instability of the peripheral part of these feedback loops. Through current international basic and clinical research, it has been found that removal of the proprioceptors can improve the frequency and amplitude of nystagmus to some extent without causing any serious complications in children, and has become a mainstream surgical procedure for the treatment of nystagmus.
