The present invention relates to a method of producing an optically detectable and retro-reflective medical tracking marker (1), wherein electromagnetic energy is applied to at least one section (4) of a retro-reflective surface (3) of a marker structure (2) in an amount that is sufficient to alter the material properties of the retro-reflective surface (3), such that the capability of reflecting electromagnetic radiation of the at least one section (4) is reduced to a second capability of reflecting electromagnetic radiation. The present invention further relates to a corresponding retro-reflective medical tracking marker (1) and a corresponding use thereof.
