title: The complement system and age-related macular degeneration.
abstract: OBJECTIVE
  Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world. There are increasing evidences to suggest the complement system may play a significant role on the pathogenesis of AMD. In this review, we summarise the current research in this area.
  
  
  METHODS
  Review of literature.
  
  
  RESULTS
  The complement system is a complex system with several activation pathways. Complement factor H (CFH) polymorphisms has been associated with increase risk of AMD. CFH is an inhibitor protein; the polymorphisms might cause uncontrolled activation by initiation events.
  
  
  CONCLUSIONS
  Further studies on the molecular basis of the complement-mediated pathogenesis of AMD may offer novel therapy to AMD.
