Intravitreal dyes are intended to make the surgical extraction of the Internal limiting membrane (ILM) safer and more complete. However, the search for an adequate vitaly dye is ongoing. The most commonly used vital dye is Indocyanine green (ICG), although it is not approved for intravitreal use and has been associated with ocular toxicity. The reason for its continued popularity seems to be that it stains the ILM better than the approved and less toxic alternative substances Brilliant Blue G (BBG) and Trypan blue (TB). According to anecdotal reports from surgeons, another reason for ICGs popularity may be the fact that it seems to make ILM removal easier. Ultimately, the intention of the investigators research is to identify possible modifications to existing dyes to reach improved intraoperative dye utility combined with a favorable safety profile. Protocol was amended and approved concerning additional use of basal membrane of deceased donors.
