Abstract：The aim of this paper is to describe the parameters and mechanisms of catch-up saccades(CS)in video head impulse tests and their relationship to vestibular functions and disorders,as the evidence of its importance in clini-cal assessment.Characteristics,mechanisms and generation of CS are described in detail,especially its roles in the ves-tibulo-ocular reflex(VOR)and cervico-ocular reflex.By assessing CS in the suppression head impulse paradigm,dy-namic visual acuity,gait and balance,we elaborate in detail on the connection between CS and vestibular functions.The article also analyzes the performance of CS under various conditions,including age,vestibular function damage,Me-niere's disease and vestibular migraines,to provide an understanding of the role of CS in various disease conditions.CS plays a crucial role in maintaining visual stability and in assessing vestibular functions impairment and vestibular reha-bilitation.
