Intended Use

The Ulmer Video Nystagmograph System is intended for use by the physician as an aid for the detection and diagnosis of vestibular disorders. The Ulmer VNG detects and displays eye position and movement in response to a number of vestibular stimulations, i.e. saccadic test, smooth pursuit, optokinetic nystagmus, caloric tests, and kinetic vestibular tests. The Ulmer VNG records and analyzes the bilateral, monocular, horizontal, and vertical aspects of eye position and movement. This device is intended to be used in a doctor's office or health care facility to obtain recorded data of nystagmus by directly observing eye motion by videocameras. The resulting recorded data is evaluated by a trained physician and considered along with other relevant data in diagnosing vestibular disorders.

Device Story

System captures eye position/movement via videocameras; records bilateral, monocular, horizontal, and vertical eye data. Used in doctor's offices/healthcare facilities by physicians. Device displays and analyzes responses to vestibular stimulations (saccadic, smooth pursuit, optokinetic, caloric, kinetic). Physician evaluates recorded nystagmus data alongside clinical findings to diagnose vestibular disorders. Benefits include objective visualization and recording of eye motion for diagnostic support.

Clinical Evidence

No clinical data provided; device relies on established principles of vestibular testing and video-based eye tracking.

Technological Characteristics

Video-based nystagmography system; utilizes videocameras for direct observation of eye motion; records and analyzes horizontal and vertical eye position/movement; intended for clinical/office environment.

Indications for Use

Indicated for use by physicians to aid in the detection and diagnosis of vestibular disorders in patients undergoing vestibular stimulation tests (saccadic, smooth pursuit, optokinetic, caloric, and kinetic).

Regulatory Classification

Identification

A nystagmograph is a device used to measure, record, or visually display the involuntary movements (nystagmus) of the eyeball.
