A simple surgical solution for the treatment of persistent postoperative hypotony after PRESERFLO MicroShunt implantation

Background: /Objectives: PRESERFLO MicroShunt implantation is a relatively new and increasingly popular treatment for recalcitrant glaucoma. Though relatively uncommon, persistent, or severe postoperative hypotony may occur and its treatment presents a significant challenge. Subjects/Methods: Interventional case series of the first 7 consecutive patients who underwent the insertion of a rip-cord suture to treat severe or persistent postoperative hypotony. Results: : In 6 patients, the hypotony resolved and vision was restored (table 2). The 7th patient had suffered a severe supra-choroidal haemorrhage with a poor visual recovery and limited follow-up, so success was more difficult to assess. Conclusions: : Stenting the PRESERFLO MicroShunt with a rip-cord suture is a simple technique to correct persistent or severe postoperative hypotony.
