PRÉCIS: Intraluminal 3-0 Supramid stent placement can be an effective long-term solution for hypotony after glaucoma drainage device surgery. This procedure may obviate the need for conjunctival dissection. In some cases, additional procedures are required.
PURPOSE: To describe the utility of implantation of a multifilament polyamide suture (Supramid) in the tube lumen to reverse hypotony after glaucoma drainage device (GDD) surgery.
PATIENTS: Patients who underwent tube revision with intraluminal placement of a 3-0 Supramid stent, with or without external ligature, to manage hypotony following GDD surgery between January 2010 and October 2020.
METHODS: Resolution of hypotony was defined as IOP >5 mm Hg and the absence of hypotony-related structural abnormalities. Overall success was the absence of failure criteria (IOP ≤5 mm Hg, >21 mm Hg, or <20% reduction below baseline IOP after 3 months for 2 consecutive study visits; additional glaucoma surgery; or loss of light perception), with or without adjunctive ocular hypotensive therapy.
RESULTS: Nine eyes of 9 patients underwent placement of a 3-0 Supramid stent with a resolution of hypotony in all eyes with a mean follow-up duration of 33.3 ±24.0 months. Overall success was achieved in 7 of 9 eyes. Four eyes required intervention after stent placement: 1 eye required selective laser trabeculoplasty followed by replacement of the original stent with a shorter 3-0 Supramid suture and external ligature; 1 eye underwent revision for tube exposure; and 2 eyes underwent laser suture lysis to release an external suture ligature.
CONCLUSIONS: In cases of hypotony after GDD, particularly when it is desirable to reduce the extent of additional conjunctival dissection, intraluminal placement of a 3-0 Supramid stent via an intracameral approach can be an effective long-term solution. Postoperative adjustments were required in many cases.
