BIO-BLUE DUO is a single injection designed for staining the membranes, ILM as well as ERM and PVR membrane, without compromising the staining effect. It is injected in the vitreous cavity to clearly differentiate between the stained and unstained part of membranes and helps in easy removal of selected membrane. The combination with PEG 4% is found as stable dye and can also be injected in the eyes filled with BSS. Also it penetrates deep and stains only the targeted membrane or tissue.
