title: [Unilateral optic disc edema: retrospective study of fifty-two patients].
abstract: OBJECTIVE
  To study the epidemiologic and clinical characteristics of patients with unilateral optic disc edema diagnosed in the emergency room (ER).
  
  
  METHODS
  Retrospective observational study of all cases of unilateral optic disc edema seen in the ophthalmology ER of Bordeaux University Hospital, France, between October 1, 2008 and October 31, 2009.
  
  
  RESULTS
  Fifty-two patients with unilateral optic disc edema were studied, including 61.5% women (n=32) and 38.5% men (n=20). Mean age was 53.5 years (± 22.9). Male patients were older than female (61.1 years vs 48.7 years, P=0.05). Final diagnosis was anterior ischemic optic neuropathy (27 cases), papillitis (17 cases), papilledema (three cases), and pseudoedema (two cases). No etiologies were identified for the remaining three patients.
  
  
  CONCLUSIONS
  Our study discusses the diagnostic approach for patients presenting with unilateral optic disc edema; this discussion may help to improve clinical practice.
