New Tests in Vestibular Assessment with VisualEyes™ 3.2!

VisualEyes™, one of the most common video nystagmography (VNG) systems used in vestibular system assessments, has been made more comprehensive and functional with version 3.2, developed by Interacoustics. The new version aims to address the assessment of dizziness and balance disorders in clinical practice with a more accurate and holistic approach.

🧪 New Tests Added with the Update

🔹 fvHIT™ (Functional Vision Head Impulse Test)

This newly developed test combines the principles of the Video Head Impulse Test (vHIT) and the Gaze Stabilization Test (GST), allowing for the assessment of an individual's ability to maintain visual fixation during head movement. This approach considers not only the biophysical measurement of the vestibulo-ocular reflex (VOR) but also how the person experiences visual stability in dynamic environments in daily life. fvHIT™ offers the clinician a more functional perspective, specifically revealing the extent to which visual clarity can be maintained during high-speed head movements.

🔹 Cervical-Ocular Tests: Cervical Gaze & Smooth Pursuit Neck Torsion

These tests contribute to a more accurate identification of conditions like cervicogenic vertigo by analyzing the effects of the cervical spine and neck movements on eye movements. Especially in individuals with complaints of dizziness related to the neck's musculoskeletal system, these tests facilitate the differentiation of cervically-sourced symptoms from central or peripheral vestibular disorders.

🔹 Self-Paced Saccade Test

This test evaluates saccadic eye movements performed voluntarily by the individual. This assessment, which sheds light on the higher-level control processes of the oculomotor system, provides noteworthy information, particularly in the analysis of central vestibular pathologies. The evaluation of saccadic eye movements is associated with attention, reaction time, and frontal cortical activity. Therefore, the test is valuable not only for examining eye movement but also for investigating neurocognitive processes.

🔍 Enhancements for Research Module Users

The additional features that come with VisualEyes™ 3.2 are not limited to clinical assessment tests. New tools that will be highly beneficial for researchers have also been integrated into the system:

• The blinking fixation light feature allows for the analysis of attention shifts or the flexibility of fixation ability during a test.

• New parameter options in caloric and optokinetic tests are offered, enabling more detailed customization of test protocols.

  
  

💬 What Does the Clinical Feedback Say?

According to Dr. Elizabeth Fuemmeler, Clinical Product Manager at Interacoustics:

“Thanks to the new features, we can better understand the source and degree of the disorder. This helps us create more accurate recommendations and effective rehabilitation plans for patients.”

🔚 Conclusion

The VisualEyes™ 3.2 update can be considered not just a technological improvement but a development that strengthens the clinical decision-making process, enhances the patient experience, and deepens data analysis. These innovations, developed for a more precise assessment of individuals with symptoms related to the vestibular system such as dizziness, loss of balance, and vertigo, will play a major role, especially in differentiating symptoms originating from the otolith and cervical systems.
