The iris cerclage suture for permanent mydriasis: A running suture technique

Permanent mydriasis can be a disabling condition. The author describes an i ris cerclage running suture technique for the treatment of permanent mydria sis caused by diffuse iris sphincter damage. A long, curved transchamber ne edle on 10-0 polypropylene is passed in and out of the anterior chamber thr ough limbal paracentesis openings while weaving the needle through the iris near the pupillary margin to form the cerclage. The technique minimizes st retching and distortion of the iris and creates a pupil that is precisely s ized and rather round.
