Comparative Toxicology of Trypan Blue, Brilliant Blue G, and Their Combination Together with Polyethylene Glycol on Human Pigment Epithelial Cells

Abstract

For short incubation times, all dyes appear equally safe. For longer incubation times, TB preparations were more toxic than BBG preparations. The toxicity of TB was reduced by the addition of PEG. Further studies are required to determine the clinical impact of this finding.
