title: Subconjunctival cysts following silicone oil injection: a clinicopathological study of five cases.
abstract: OBJECTIVE
  To study the occurrence, risk factors and management of subconjunctival cysts formed following the use of intraocular silicone oil as a tamponade.
  
  
  METHODS
  We analyzed 5 cases of single and multioculated subconjunctival oil cysts between 1986 and 1996.
  
  
  RESULTS
  Cysts were observed 15 days to 4 months following silicone oil injection. Clinically they showed minimal inflammatory signs but histopathology of removed cysts showed emulsified silicone oil globules with chronic inflammatory cellular infiltration.
  
  
  CONCLUSIONS
  Though silicone oil is considered to be nontoxic, it can cause chronic inflammation when spilled into the subconjunctival space.
