Sonographic nystagmus: a case report of lateral semicircular canal benign paroxysmal positional vertigo

This is the first report on the use of ocular ultrasonography to assess nystagmus. Despite certain limitations, this technique may be a valuable supplementary tool, particularly in settings in which conventional examinations are hindered or unavailable. Ophthalmic sonography has the potential to enhance vestibular assessments in emergency and outpatient settings.
