In cases with congenital nystagmus (CN), the study of vestibular function is difficult by many factors had connection with the measurement of the vestibulo-ocular mechanical (VOR) by means of caloric experiment and the video head impulse test (vHIT), and to date no aforementioned studies have successfully working the vHIT to evaluate vestibular function in these patients. We present a case accompanying CN and vertigo at which point peripheral vestibular function was evaluated utilizing the vHIT system, containing head impulse testing and the abolition head impulse agreement. We show that it is possible (a) to identify sideways VOR changes such as deformities resembling those produced by mutual vestibular lesions, though not necessarily had connection with the same mechanism; (b) to recognize peripheral VOR lesions of the upright semicircular canals (SCC); and (c) to document compensation and improvement subsequent to these minor lesions during follow-up of sufferers with CN. vHIT is a valuable tool that should be used to study vestibular function in inmates with CN and dizziness, which could comprise a new clinical request of this technique.
