ROSE BENGAL (Acid red 94)

Rose Bengal is a reddish-brown powder that is commonly employed in biological and diagnostic staining applications. The dye is best known for staining dead and degenerating cells along with mucus, making it useful in microscopic and clinical examinations. Rose Bengal is also widely employed in the detection of damage to the ocular surface epithelium in ophthalmic diagnostics. It is useful in the diagnosis of ocular surface disorders including dry eye conditions and herpetic keratitis by highlighting affected or damaged epithelial regions during examination. Its staining characteristics support clearer visualization of compromised tissue areas, assisting in diagnostic evaluation and clinical observation. Beyond ophthalmology, the dye is also applied in laboratory and research settings involving cellular staining and tissue studies. Due to its reliable staining properties and diagnostic usefulness, Rose Bengal is still considered a key reagent in pathology, microscopy, and ocular research applications.
