- Abstract
Objectives: To evaluate acoustically evoked cervical and ocular vestibular miogenic potentials (AC cVEMP and oVEMP) findings in patients diagnosed with Susac's syndrome (SS). Material and methods: Two patients with SS were tested. The stimuli (500 Hz frequency tone bursts) were presented unilaterally one ear at a time. 'The resulting VEMP waveforms were analyzed for the response presence, latency and amplitude in the time domain. Results: Patient#1, responses on both sides showed latencies within normal limits for both c- and oVEMP; small amplitudes for cVEMP. Patient#2, only cVEMPs were present; latencies within normative values, amplitudes low and asymmetric between sides. Conclusions: The combined application of AC cVEMP and oVEMP may provide additional and useful information about affected vestibular system and be of help in treatment and rehabilitation planning in patients with Susacs syndrome.
