    Purpose To describe a novel technique of staining the internal limiting membrane (ILM) in eyes with retinal detachment (RD) using perfluorocarbon liquid (PFCL). Method The technique was used in 10 eyes of 10 patients. Following posterior vitreous detachment induction, PFCL was gently injected using a silicon soft-tip cannula pointing toward the optic disc. Brilliant blue G dye (BBG) was then injected under PFCL bubble using a silicon soft-tip cannula. ILM peeling was completed under PFCL. Result ILM stained instantaneously in all eyes with BBG using this technique. ILM peeling was completed successfully in all eyes. Conclusion Practical implications over current staining techniques: Decreases the surgical time, as no need to wait for 30-60 seconds for the ILM to stain; PFCL provides countertraction (third hand) for peeling the ILM in detached retina. This technique can also be used to stain fast with minimal dye in attached retinas; the smaller the amount of dye used, the smaller the toxic effect.
