Urolene Blue

Methylene blue, a vital stain (Urolene blue), has properties similar to those of rose bengal. It can stain both devitalized cells and mucus and corneal nerves. It is not a specific stain when applied to the eye because the blue areas may be either cells or mucus. Clinically, methylene blue is useful for staining the lacrimal sac before dacryocystorhinostomy and outlining glaucoma filtering blebs, and it may prove useful in gonioscopic laser sclerostomy. More recently it has been used in vitro (tissue extraction and absorbance at 660 nm) to examine the effects of...
