Abstract
First, a coloured solution is claimed, comprising at least one perfluorocarbon as a solvent and a dye dissolved in the perfluorocarbon and selected from the family of fluorinated derivatives of phthalocyanines obtained by substituting one or more of the hydrogen H atoms linked to the benzene rings with a fluorine atom or a fluorinated group, for use in surgical methods for the treatment of the bodies of humans or animals, in particular in surgical methods of vitreoretinal surgery where the coloured solution acts as a retinal tamponade. Second, a coloured solution is claimed, comprising at least one perfluorocarbon selected from perfluorooctane, perfluorodecalin and perfluorophenanthrene as a solvent and a dye dissolved in the perfluorocarbon and selected from the family indicated above. The dye, in general, is preferably selected from the family of metalpoly(fluoroalkyl)phthalocyanines and even more preferably of metalpoly(perfluoroalkyl)phthalocyanines.
