[Substances for staining biological tissues: use of dyes in ophthalmology].
The azo dye trypan blue and the cyanine dye indocyanine green have been used in ophthalmology since the 1980 s to dye the anterior capsule in cataract operations and to stain epiretinal membranes in order to remove the membrana limitans interna (ILM). By means of a standardized in vitro test in accordance with DIN EN ISO 10993, it has now been shown that both dyes and the theoretically possible alternatives - the anthrachinone alizarincyanine green and the trityl dyes fast green and lissamine green - are cytotoxic in the normal concentrations of maximum 1.5 g/l. On the other hand, the new product Blueron(R) with the trityl dye patent blue, which has been developed to dye the anterior capsule, is completely biocompatible, even at a high dosage of up to 2.8 g/l.
