  • Title: Cyanine dyes as optical contrast agents for ophthalmological surgery.
    Author: Langhals H, Varja A, Laubichler P, Kernt M, Eibl K, Haritoglou C.
    Journal: J Med Chem; 2011 Jun 09; 54(11):3903-25. PubMed ID: 21524061.
    Abstract:
    Cyanine dyes were prepared as optical contrast media for supporting the surgery of the lamina limitans interna (LLI) of the retina and other structures of the human eye. Their absorption spectra were adapted both to the spectral sensitivity of the human eye and to standard illumination. The contrast could be further amplified by the application of the strong fluorescence of the dyes used. The binding of the dyes to various surfaces was studied. No toxic effects could be detected for the applied dyes.
