A Predictive Score for the Ischemic Etiology of a Transient Diplopia (VASCO-DIP)

Recruiting

• Conditions: Diplopia

• Registration Number: NCT02576925
• Lead Sponsor: Fondation Ophtalmologique Adolphe de Rothschild

Brief Summary

The transient diplopias (TD) is defined by a short diplopia. 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 TD .
