Abstract
The invention relates to a water-based biocompatible non-cytotoxic preparation for the selective staining of internal limiting membrane (ILM) and/or epiretinal membranes (ERM) in the human or animal eye, and to a kit containing said water-based preparation according to the invention.
Claims10
A method of staining and removing the internal limiting membrane (ILM) and/or of epiretinal membranes (ERM) in the human or animal eye, comprising
- preparing a water-based, biocompatible eye membrane dye solution comprising at least one dye selected from the group consisting of triphenylmethane dyes, azo dyes, cyanine dyes, natural dyes, and mixtures thereof, wherein the eye membrane dye solution has a density in the range of 1.01 g/cm3 to 1.5 g/cm3, wherein the eye membrane dye solution has a dynamic viscosity in the range of 1 to 500 mPas at 25° C. and a shear rate of 10 s−1 with the proviso that monosaccharides or reducing disaccharides are not used for adjusting the density;
- staining the ILM and/or of ERM by using the eye membrane dye solution;
- and
- removing the stained ILM and/or ERM.
