Rose bengal solid and solution in water. Rose bengal (4,5,6,7-tetrachloro-2',4',5',7'-tetraiodofluorescein) is a stain. Rose bengal belongs to the class of organic compounds called xanthenes. [1] Its sodium salt is commonly used in eye drops to stain damaged conjunctival and corneal cells and thereby identify damage to the eye.
After intravenous injection of photosensitive dyes like rose-bengal, the brain is irradiated through the skull via a small hole or a thinned cranial window, leading to photochemical occlusion of the irradiated vessels with secondary tissue ischemia . This approach was initially proposed by Rosenblum and El-Sabban in 1977, and improved by Watson ...
Rose Bengal is a well-recognized photosensitizer and its phototoxicity has been well-documented. Its cytotoxic mechanism of action in the absence of light activation, however, is less well understood.
The rose bengal test uses a stain that measures the state and function of the lacrimal glands. This test involves placing the nontoxic dye rose bengal on the eyes. The dye's distinctive colour helps in determining the state and functioning of the tear film and the rate of tear evaporation.

Xanthene Rose Bengal. Xanthene-based sensitizers, on the other hand, have shown successful cytotoxicity in vitro by producing reactive oxygen species after being triggered by ultrasound. [1] More research is necessary to improve its potential in vivo performance since it is quickly processed by the liver and cleared from the body. [1]
Alongside diet and exercise changes, participants took a once-weekly semaglutide injection or a placebo for 68 weeks. Participants taking semaglutide lost almost 15 percent of their body weight.
For non-responsive cases, potential treatments include topical ciclosporin A, [8] vitamin A, [9] autologous serum [10] and injections of triamcinolone. [11] Surgical treatment options include thermocauterization of the bulbar conjunctiva [12] and conjunctival resection, [13] typically under rose bengal (RB) staining to visualize affected areas. [7]
