Clinical Trial Summary

Vestibular neuritis is a brutal and continuous dizzying syndrome of peripheral (vestibular) origin without cochlear or other associated involvement. Specifically, vestibular neuritis is inflammation of the nerve that innervates the vestibular canals (the inner ear). It is characterized by the sudden onset of intense and prolonged vertigo accompanied by postural imbalance, nausea and vomiting, without hearing impairment or other neurological symptoms. Vestibular neuritis is the second cause of peripheral vertigo after benign paroxysmal positional vertigo. It represents approximately 7% of patients consulting for vertigo. The purpose of this study is to evaluate if wearing Boarding Ring glasses can be accelerated vestibular compensation.

• Vestibular Neuronitis

Intervention

Diagnostic Test:
• Caloric test
Lying, patientwill be placed so that he can introduce water (hot then cold) into his external ear canal. It is the reaction of the vestibular system (sensory organ responsible for balance) which is then measured with a helmet placed over his eyes and which measures the nystagmus (movement of the eye) which reflects vestibular activity.
• Measurement of the speed of Nystagmus
A helmet with an infrared camera will be placed in front of patient eyes. This will allow visualizing on screen and measuring eye movements spontaneous or induced in the dark by various tests.
• Angle of deviation at Fukuda
The patient will be asked to trample on the spot (30 steps) with the indexes pointed forward. In the event of vestibular asymmetry, the patient turns at a varying angle to the right or to the left. This will then measure what is called the angle of deflection of the fukuda.
• Alexander's degree of nystagmus
there are 3 degrees: Degree I: nystagmus that exists only when the eyes are turned to the right. Degree II: also exists when the eyes are to the right or to the front. Degree Ill: exists when the eyes are on the right, front, or left

Other:
• EHTEV questionnaire
Handicap Scale for Balance Disorders and Vertigo
• EEV questionnaire
European Vertigo Assessment Questionnaire
• anxiety VAS
visual analog scale of anxiety

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Variation of the angle of deviation at the Fukuda test between J0 and J7 (value at J0 minus value at J7).		7 day
Secondary	Speed of nystagmus		1 year
Secondary	Alexander's degree of nystagmus	Measure of the degree of intensity of nystagmus. There are 3 degrees : Degree I: nystagmus which exists only when the eyes are turned to the right.; Degree II: also exists when the eyes are to the right or to the front.; Degree Ill: exists when the eyes are on the right, front, or left.	1 year
Secondary	Duration of hospitalization (for hospitalized patients)		1 year
Secondary	Anxiety visual analog scale	0 = no anxiety, 10 = maximum anxiety imaginable	1 year
Secondary	Handicap related to Balance Disorders and Vertigo scale (EHTEV questionnaire)	It helps to determine the physical, emotional and functional difficulties experienced in everyday life. EHTEV questionnaire is scored on 100 points.; The physical score from 0 to 28 points, the emotional score from 0 to 36 points and the functional score from 0 to 36 points. ( 0 = no difficulty).	1 year
Secondary	European Vertigo Evaluation Scale (EEV questionnaire)	Makes it possible to quantify vertigo and the associated vestibular symptoms and to monitor their evolution. EEV questionnaire is scored on 20 points (0 = no symptoms, 20 = maximum symptoms)	1 year
Secondary	Vestibular deficit at caloric tests	measures 7of nystagmus (= fluttering of the eye) which reflects vestibular activity	1 year
Secondary	Variation from J0 of the angle of deviation at the Fukuda measured at J14, M1, M3, M6, M12		1 year
