Best ILM staining due to high purification -minimum 97% purity


ILM-Blue® is a dye to stain the ILM in vitreoretinal surgery.

By injecting ILM-Blue® in the vitreous cavity the ILM 
will be clearly stained and easily distinguished from the underlying, unstained retina and can be removed selectively.

Due to a new integrated carrier 4% PEG solution, ILM-Blue® 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 staining due to high purification - minimum 97% purity 
ILM-BLUE®: Posterior Dye for staining the ILM consists of: 

BBG 0,025% + 4% PEG

Highly purified BBG - minimum 97% purity


Best injection characteristics due to new "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.

Purity & safety

LM-Blue® is produced with highly purified BBG at a drug substance level.

Safety tests

Toxicity tests on ARPE-19 human retinal pigment epithelium cells showed an advantageous safety profile of the new products ILM-Blue®. Increased purity of the dyes as well as the addition of PEG3350 results in even safer products. Safety testing was complemented by electron microscopy ultrastructural analysis and in vitro cytotoxicity tests according to ISO-10993.
