Area of Science:

  • Neurology
  • Medical Technology
  • Artificial Intelligence

Background:

  • Benign paroxysmal positional vertigo (BPPV) is the most prevalent vestibular disorder.
  • Current BPPV diagnosis relies on manual observation of nystagmus during positional changes.
  • An increasing patient-to-specialist ratio necessitates automated diagnostic solutions.

Purpose of the Study:

  • To develop an automated system for diagnosing BPPV using video-nystagmography (VNG) data.
  • To enhance the accuracy and efficiency of BPPV diagnosis through artificial intelligence.

Main Methods:

  • Proposed ANyEye, a convolutional neural network (CNN)-based system for nystagmus extraction from VNG data.
  • Implemented pupil segmentation and trajectory tracking for precise eye movement analysis.
  • Developed algorithms for pupil position compensation and motion artifact removal due to goggle slippage.

Main Results:

  • ANyEye achieved a 91.26% detection rate with a five-pixel error.
  • The system demonstrated superior performance compared to existing eye-tracking methods.
  • Successfully addressed challenges of real-world VNG data, including motion artifacts.

Conclusions:

  • The ANyEye system offers a promising automated approach for BPPV diagnosis.
  • AI-powered analysis of VNG data can significantly improve diagnostic accuracy and accessibility.
  • This technology has the potential to alleviate the burden on specialists and improve patient care.
