Rose bengal is a pink stain derived as an analogue of fluorescein. Its disodium salt in ophthalmic solutions has been used as a diagnostic agent in suspected damage to conjunctival and corneal cells. It is also used in laboratory settings, including the preparation of Foraminifera for microscopic analysis and suppression of bacterial growth in several microbiological media. A direct cytotoxic effect of Rose bengal on microorganisms and cancer cells has been observed, questioning its potential antitumor actions via intralesional injections. The clinical applications of rose bengal as injectable formulation under the name PV-10 in melanoma, breast cancer and skin conditions such as eczema and psoriasis are being investigated in clinical trials.

Rose Bengal stains both the nuclei and cell walls of dead or degenerated epithelial cells of the cornea and conjunctiva, and stain the mucus of the precorneal tear film. It is proposed that the staining ability of rose bengal is dependent on the status of tear film protection rather than cell viability, as tear components such as albumin and mucin can block the rose bengal uptake . It induces intrinsic cytotoxic effects by causing cellular morphologic changes, subsequent loss of cellular motility, cell detachment, and cell death . It mediates inhibitory actions on bovine corneal endothelial cells and attenuates cell proliferation .
Indicated as a diagnostic agent in routine ocular examinations or when superficial conjunctiva or corneal tissue change is suspected, and as an aid in the diagnosis of keratoconjunctivitis sicca, keratitis, abrasions or corrosions as well as the detection of foreign bodies.
