Dizziness test devices
moving on to a new stage

Features of PitEye

It is estimated that there are approximately 500,000 patients suffering from vertigo nationwide, or 2.67 million* if latent patients are included. However, the number of doctors specialized in vertigo in the department of otorhinolaryngology are less than 10% of the total number. The current situation is that sufficient medical care is not being provided to all of the patient. One of the reasons for this is the high hurdle in introducing dizziness testing equipment.
*Quotes from the Ministry of Health, Labour and Welfare's "Overview of the 2019 National Survey of Basic Survey of People's Lives"

  • The cost of testing equipments are high.
  • Operation of the quipments are complicated with high learning costs.
  • Separate testing equipments are required for specialized test.
  • Insufficient space for equipment installation.
  • Lack of vertigo specialists.

PitEye was born out of these issues from the voice from doctor.
