What does rose bengal stain?

Explanation:
Rose bengal highlights damaged surface and mucus. It binds to dead or degenerating epithelial cells where the cell membranes are compromised and to mucus/mucin-containing secretions from the ocular surface. Healthy, intact epithelium resists staining because its barrier remains intact, so rose bengal primarily marks areas of epithelial damage and mucous presence. It does not specifically stain bacteria, nor does it target tear film proteins.
