Summary

This review explores vital dyes for chromovitrectomy, a technique in vitreoretinal surgery. Newer dyes show promise for visualizing retinal tissues, but indocyanine green toxicity requires careful consideration.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Retinal Surgery

Background:

  • Vital dyes are increasingly used in vitreoretinal surgery for enhanced visualization.
  • Chromovitrectomy, the application of vital dyes, aids in complex retinal procedures.

Purpose of the Study:

  • To review the current state-of-the-art of vital dye application in chromovitrectomy.
  • To overview dye properties, application techniques, indications, and complications.

Main Methods:

  • Literature review of published research on chromovitrectomy dyes.
  • Analysis of dye properties, including toxicity and visualization capabilities.

Main Results:

  • Indocyanine green exhibits dose-dependent retinal cell toxicity.

  • Newer dyes like trypan blue, patent blue, and brilliant blue are effective for specific tissues.
  • Novel instruments may allow selective tissue staining.

    • Conclusions:

    • Chromovitrectomy is an expanding field with ongoing research.
    • Indocyanine green, infracyanine green, and brilliant blue are primary choices for internal limiting membrane staining.
    • Patent blue, bromophenol blue, and trypan blue excel in epiretinal membrane visualization.
