摘要

Purpose:We will describe a minimally invasive technique for the repair of iridodialysis, without conjunctival dissections, using intrasceral fixation of a 6-0 polypropylene suture with a flanged tip.Methods:A flange was created at the end of the suture with thermoplasticity. An ab interno passing of the needle attached to the suture was performed through the peripheral part of the iris and was further passed out from the eye 1.5 mm to 2 mm behind the limbus. Intrascleral fixation of the exterior suture was performed with the aid of the attached needle. After adjusting the tension of the iris relocation, the externalized end of the suture was cut flush to the sclera with scissors. For a wide dialysis, the same manipulations were repeated until the repair was completed.Results:The technique was used in three eyes of three patients. No visual impairments of monocular diplopia and glare were observed after surgery. Postoperatively, the irises remained well positioned, with no suture erosion, suture loosening, hypotony, scleral atrophy, or chronic inflammation being observed within the follow-up period. Mild postoperative hyphema was observed in one eye of blunt trauma.Conclusion:The present technique provides minimal surgical invasion for the repair of iridodialysis without creations of scleral flap/groove/pocket and conjunctival dissection.
