“Dry Lake” technique for the treatment of hypertrophic bleb following XEN® Gel Stent placement

Abstract

Case reportThe case of a patient with previous uncomplicated XEN® drainage glaucoma surgery is described, who presented with hypertrophic bleb and mechanical ectropion. Treatment consisted of the “Dry Lake” procedure to drain the hypertrophic bleb following blockage with viscoelastic of the ab interno stent and bleb sealing with a tissue adhesive. DiscussionProposals for the management of this type of bleb include therapeutic strategies, sutures or even autologous blood. The use of Tissucol®, already described in glaucoma surgery, may be appropriate to treat this complication of XEN® placement.
