DORC Membrane Blue-DUAL®

SKU: DORC-MBD.05S Category: Tags: ,

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. Extensive tests proved that MembraneBlue-Dual® is a 100% 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 a new 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.


Best ILM & ERM staining due to high purification, up to 97% purity.
