Trypan Blue for Angle Visualization
By Bac T. Nguyen, MD
Dr. Nguyen presents his use of trypan blue to visualize the angle during MIGS. In a patient with a faintly pigmented trabecular meshwork on preoperative gonioscopy, trypan blue was used to stain the trabecular meshwork and facilitate implantation of the Hydrus Microstent (Ivantis).
“Because of this case, I changed how I teach MIGS to the residents at Baylor College of Medicine. To prepare them for MIGS, I have our senior residents tilt the microscope and rotate the patient’s head and directly visualize the angle with a Swab Jacob gonioprism during cataract cases with and without trypan blue. This helps residents become familiar with achieving the proper positioning for angle surgery, viewing the angle anatomy, and seeing how much trypan blue can improve visualization of a lightly pigmented TM. When the residents start performing MIGS, I have them use trypan blue on their first six cases to ensure that they have the best visualization possible.”

Webinar: Sutureless Scleral Fixation of IOLs
By Ashvin Agarwal, MD; Bonnie Henderson, MD; Jason Jones, MD; Steven G. Safran, MD; and Yuri McKee, MD
In this webinar recording, cataract experts discuss their pearls for glued IOLs, the Yamane technique, complex case management, and more.
“Glued IOL is my old faithful. If you know the glued IOL well, you can do a lot better with Yamane, Canabrava, and other techniques.”
