  • MEMBRANEBLUE-DUAL® is a dye to stain both the ILM as well as the ERM and PVR membrane, without compromising the staining effect within one injection.
  • By injecting MEMBRANEBLUE-DUAL® in the vitreous cavity the membrane will be clearly stained and easily distinguished from the underlying, unstained retina and can be removed selectively.
  • MEMBRANEBLUE-DUAL® is a stable mix and stains the ILM at the same level as ILM-Blue® and stains the ERM and PVR at a higher level than the classic MembraneBlue.
  • Due to an integrated carrier 4% PEG solution, MEMBRANEBLUE-DUAL® can be injected in a BSS filled eye and sinks immediately as a cohesive ball to the fundus of the eye and only stains the targeted tissue without diffusion throughout the whole globe.
