Fibrous Downgrowth

This 45-year-old woman has primary open angle glaucoma and had undergone multiple surgeries in this eye including a trabeculectomy in 2007, which required a revision and then an Ahmed stunt surgery, which also required a revision. She was hypotonus for periods during her postoperative care. She was then seen by another physician who found that her Ahmed Seton tube was impaled into her crystalline lens, which required her to have a shunt revision with a cataract extraction. She later underwent another Ahmed revision and subsequently a Baerveldt Seton with a pars plana vitrectomy and the tube placed in the posterior segment. She was referred to the University of Iowa because of the corneal changes seen in this video.
