title: Periocular infection.
abstract: OBJECTIVE
  The aim of this article is to acquaint the clinician with advances in the diagnosis and management of periocular cellulitis and to alert physicians to emerging pathogens.
  
  
  RESULTS
  The most important, recent infectious disease entity to consider is community-acquired methicillin-resistant Staphylococcus aureus, which is emerging as a significant problem across the country. The potential devastation caused by necrotizing fasciitis is also reviewed, since this diagnosis is easily missed early in its course. A variety of less common and frankly atypical pathogens is presented to remind the clinician that, on occasion, the hoofbeats are indeed a zebra's.
  
  
  CONCLUSIONS
  Periocular cellulitis remains an important and common entity in ophthalmology. The emergence of new pathogens and the resistance to conventional treatment by others are a cause for concern and require an understanding of management strategies.
