title: Epiretinal membrane surgery assisted by trypan blue.
abstract: OBJECTIVE
  To evaluate patient outcome following epiretinal membrane surgery using trypan blue to facilitate visualization and delamination.
  
  
  METHODS
  A retrospective noncomparative review of 23 patients.
  
  
  METHODS
  Patients underwent a three-port pars plana vitrectomy with delamination using trypan blue 0.06%.
  
  
  RESULTS
  The median preoperative visual acuity was 20/100. The median postoperative visual acuity was 20/60. Seventeen patients (74%) improved their visual acuity by at least 2 chart lines. No adverse reaction related to trypan blue was observed up to 1 year postoperatively.
  
  
  CONCLUSIONS
  Trypan blue staining of the epiretinal membrane facilitated visualization and delamination without any signs of toxicity.
