Tenon's traction sutures: an aid for trabeculectomy and aqueous drainage device implantation
Hill RAJournal of Glaucoma 2002; 11: 529-530
PURPOSE: To describe a surgical technique to improve visualization and surgical access for trabeculectomy and implantation of aqueous drainage devices. MATERIAL AND METHODS: After the corneal traction suture (6-0 polygalactin; S-29 needle) has been placed, a second suture is passed through tenon's capsule alone, either at the anterior edge of a limbus-based conjunctival flap for trabeculectomy, or at the incisional edge of a fornix-based conjunctival flap for drainage implant surgery. RESULTS: The incision for limbus-based peritomies must be posterior enough to take advantage of the posterior thickening of tenon's capsule when placing the traction suture. The use of traction sutures enhances visualization and limbal surgical access for trabeculectomy. They also enhance posterior ocular surface visualization and aim placement of scleral fixation sutures for securing the explants of aqueous drainage devices. CONCLUSION: This study demonstrated quantitavily that the progression of optic disk damage in glaucoma is faster in eyes with disk hemorrhage than in eyes without disk hemorrhage.
