Abstract:
Two previously healthy 14-year-old horses developed right-sided unilateral vestibular signs after they had possibly been struck by lightning. Repeated radiographic and endoscopic evaluations did not reveal any significant changes. A brainstem auditory evoked response test indicated a subtle left to right interaural latency difference of waves I, III and V in the more severely affected pony, but its central conduction time remained normal.
