The use of suture material to perform trabeculotomy was first described by Smith in 1960. The technique was subsequently refined by Beck and Lynch in 1995 when they presented a series of 26 eyes undergoing 360° trabeculotomy using a single length of 6-O polypropylene suture. In this new modification, a suture fragment is passed through the entire length of Schlemm's canal via a partial thickness scleral flap. Once passed, the 2 free ends of the suture are pulled, opening all 360° of the angle as the suture tears into the anterior chamber. The potential advantage of this technique is the ability to open the entire angle through only one incision during a single surgical procedure. By contrast, conventional trabeculotomy with metal trabeculotomes is only able to open one-third to one-half of the angle circumference at a single session and would require at least 2 separate incisions to complete for 360° angle surgery. This report describes a potential complication of suture trabeculotomy; false passage into the subscleral (suprachoroidal) space.
