F55 Deep Sclerectomy Assisted by Trypan Blue in Combined Surgery for Open-Angle Glaucoma

Video describes the steps to stain the loose collagen of the juxtacanalicular trabecular meshwork with trypan blue during combined cataract and filtration procedure.  Once it is stained the surgeon is able to remove this barrier to aqueous humor egress and will have more confidence on the quality of the filtration pathway.
