    In this video, Steven D. Vold, MD, demonstrates a slit-lamp bleb revision using mitomycin C and Healon 5. Using a 27-gauge needle, he injects 0.2 milliliters of a 50/50 mixture of mitomycin C (0.4 mg/ml) and 1% preservative-free lidocaine. Using the same subconjunctival needle site he then injects Healon 5 into the subconjunctival space. This provides good visualization and maintains the subconjunctival space for approximately five to seven days, which may improve the outcome of the procedure. The 27-gauge needle is then used to refashion the flap and enter the anterior chamber.
