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 .
