Effective ILM & ERM staining

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.

Effective ILM & ERM staining due to high purification – minimum 97% purity
MEMBRANEBLUE-DUAL®: Dye for staining ILM, ERM & PVR membranes consists of: 

Combination of TrypanBlue 0,15% + BBG 0,025% + 4% PEG

Highly purified TB + BBG – minimum 97% purity

Advanced injection characteristics due “carrier” 4% PEG solution
Creates better injection characteristics under BSS.
Sinks immediately to posterior pole as a cohesive ball. 
Stains only target tissue and no diffusion throughout the eye.
