In this episode, Dr Solish and I discuss the art of “needling” a filtering bleb, or as he likes to call it, a Slit Lamp Revision (SLR), to resuscitate its function. Beginning with the history of when he first thought of the idea as a resident and it was shot down and how this evolved to using antimetabolites in conjunction with the needling in order to discourage fibroblasts from forming more scar tissue from the procedure. You might be surprised to learn what types of blebs are more  likely to improve with Slit Lamp Revision! (See the enhanced version of this podcast for chapter markers and images.)
