Abstract

Purpose: To report a case and management of persistent hypotony with hypotony-induced maculopathy after CyPass® device implant. Background: The CyPass® was the first supraciliary ab interno device approved by FDA and commercially available. Efficacy studies showed adequate intraocular pressure (IOP)-lowering results in combination with phacoemulsification. Hypotony induced by suprachoroidal minimally invasive glaucoma surgery (MIGS) was reported to be lower than 3% in the population that comprised the COMPASS study. Case description: A 57-year-old female patient with mild open-angle glaucoma with maximum topical medical therapy who underwent sequential bilateral CyPass® implantation developed persistent hypotony. Device obstruction was induced through argon laser burns directed to the peripheral iris, and the device was no longer visible on follow-up examinations. Topical IOP-lowering medication was restarted (timolol–dorzolamide) and has since been controlled under 16 mm Hg, without progression on visual fields. Conclusion: Argon laser burns directed to the peripheral iris to induce synechiae development that produces device obstruction are an effective technique to manage persistent hypotony after supraciliary CyPass® implantation. Clinical significance: Here, authors show a novel approach for treatment of persistent hypotony secondary to CyPass® implantation. In the knowledge of the authors, this is the first report that describes a noninvasive management for this complication, and this case could help other physicians to manage similar cases.
