Vertigo Teaching Atlas
Vertigo Teaching Atlas
An interactive teaching atlas of vestibular testing — VNG, nystagmus, VEMPs, vHIT and electrocochleography.
From bedside oculography to instrumented vestibular testing. Five modalities, each indexed by the clinical question it answers and the patterns it produces — recordings, interpretation rules, and the pitfalls every ENT and neurology trainee should recognise.
Modalities
Videonystagmography
LiveGoggles-recorded battery: gaze, smooth pursuit, saccade, optokinetic, positional, and bithermal caloric testing.
Nystagmus Patterns
LiveLibrary of nystagmus types and their localising value — peripheral, central, paroxysmal, gaze-evoked, congenital.
VEMPs
LiveCervical and ocular vestibular evoked myogenic potentials — technique, asymmetry ratios, and diagnostic patterns.
Video Head Impulse Test
LiveCanal-specific gain testing for all six semicircular canals — recognising covert and overt catch-up saccades.
Electrocochleography
LiveSP/AP ratio in suspected endolymphatic hydrops — recording, waveform interpretation, and pitfalls.
Each modality folds into this hub as it is lifted from its original subdomain.
