Management of Ocular Hypotony After Tube Surgery Using Bent Intraluminal Stents

Abstract

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.
