rose bengal 

An iodine derivative of fluorescein having vital staining properties but unlike fluorescein it is a true histological stain, which binds strongly and selectively to cellular components. The colour of this stain is red. It has the disadvantage of causing some pain in a good percentage of eyes. It stains dead or degenerated epithelial cells but not normal cells and is used to help in the diagnosis of corneal abrasion, keratitis, keratoconjunctivitis sicca, lagophthalmos, etc. See fluorescein; lissamine green.

rose bengal

a fluorescein compound used as a pink dye, in a liver function test, and as a coloring agent in feed. It is also used in the eye to stain necrotic tissue and devitalized cells of the cornea in keratitoconjunctivitis sicca. Animals injected with the dye are temporarily photosensitive.

rose bengal test
an oldfashioned field plate test for brucellosis in serum. The dye was used to mark the antigen and make its clumping visible. Suitable only as a screening test.
