A Predictive Score for the Ischemic Etiology of a Transient Visual Disturbances (VASCO)

Completed

• Conditions: Vision Disorders

• Registration Number: NCT02485054
• Lead Sponsor: Fondation Ophtalmologique Adolphe de Rothschild

Brief Summary

The transient visual disturbances (TVD) are defined by a short abnormality of visual function. Their etiology may be ophthalmological, neurological non-ischemic or of ischemic origin.

The difficulty is to recognize an ischemic mechanism which imposes emergency cares.

A clinical score could help the clinician to recognize the etiology of the TVD .
