Summary

Trypan blue safely enhances epiretinal membrane surgery by improving visualization and delamination. This method led to significant visual acuity improvements in most patients without adverse effects.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Epiretinal membranes (ERMs) can cause visual distortion.
  • Accurate visualization and removal are crucial for successful ERM surgery.

Purpose of the Study:

  • To assess patient outcomes after ERM surgery using trypan blue for enhanced visualization and delamination.
  • To evaluate the safety and efficacy of trypan blue in this surgical context.

Main Methods:

  • Retrospective review of 23 patients undergoing ERM surgery.
  • Three-port pars plana vitrectomy with trypan blue (0.06%)-assisted membrane delamination.

Main Results:

  • Median visual acuity improved from 20/100 preoperatively to 20/60 postoperatively.
  • 74% of patients experienced at least a 2-line improvement in visual acuity.

  • No trypan blue-related adverse reactions were noted up to 1 year post-surgery.

    • Conclusions:

    • Trypan blue staining effectively aids in visualizing and delaminating ERMs.
    • The use of trypan blue in ERM surgery appears safe and does not induce toxicity.
