In which scenario is Methylene Blue Dye typically employed?

Methylene Blue Dye is commonly used in ophthalmic procedures to outline glaucoma filtering blebs. This application is important because it allows for better visualization of the surgical site, particularly in identifying the success of the filtration procedure and assessing any postoperative complications. The dye highlights the blebs, making it easier for the surgeon to evaluate their status and functionality during follow-up assessments.

This practice is particularly beneficial in managing glaucoma because the formation of filtering blebs is a critical component of glaucoma surgery aimed at reducing intraocular pressure. The distinct color contrast provided by Methylene Blue enhances the clarity of the surgical field, thus facilitating better surgical and clinical decisions. While other options mentioned may involve different dyes or anesthetics and perform other functions in ophthalmology, Methylene Blue's primary role in this context is specifically in the visualization of filtering blebs.
