Management of ocular hypotony after tube surgery using bent intraluminal stents

Purpose:We aimed to report a surgical technique for the management of ocular hypotony after tube surgery.Methods:We occluded the tube with ab interno insertion of 2 bent 5-0 polypropylene threads into the tube lumen. Bent stents were used to prevent stent displacement.Results:Our case series revealed that this procedure effectively resolved hypotony. Among the 3 cases, the stents were removed in 1 case and left in place in 2 cases. In all cases, the stent location remained stable without displacement.Conclusion:The insertion of bent intraluminal stents into the tube may be a useful method for the management of ocular hypotony after tube surgery.
