title: Topical gel vs subconjunctival lidocaine for intravitreous injection: a randomized clinical trial.
abstract: OBJECTIVE
  To determine if topical gel is superior to subconjunctival injection of lidocaine in relieving pain of intravitreous injection of corticosteroid.
  
  
  METHODS
  Randomized clinical trial.
  
  
  METHODS
  
  
  
  METHODS
  One hundred patients receiving intravitreous injection of triamcinolone. INTERVENTIONAL PROCEDURE: Topical lidocaine 2% gel and subconjunctival lidocaine 2% injection.
  
  
  METHODS
  Analog pain score assessment, conducted by technician masked to treatment.
  
  
  RESULTS
  There was no statistically significant difference in pain scores between the treatment groups (P = .1).
  
  
  CONCLUSIONS
  The effective relief of pain with lidocaine for intravitreous injection is independent of its mode of application (gel vs subconjunctival injection).
