Methods: A 67-year-old caucasian female with advanced primary angle-closure glaucoma on four medications with an intraocular pressure (IOP) of 26 mm Hg was listed for a PMS insertion with mitomycin C (MMC).
Results: Past ocular history was significant for pseudophakia and previous yttrium aluminum garnet (YAG) peripheral iridotomy.
We present a case of advanced glaucoma with previously failed trabeculectomy who underwent a Baerveldt tube (BVT) insertion, with initial success. However, 9 months post BVT insertion he developed profound clinically significant hypotony. Two attempts at controlling this with suture exchange led to episodes of significant ocular hypertension, followed by hypotony each time.
