Results of a novel surgical technique for iridodialysis repair using an iris retractor segment

Abstract

Purpose: To describe a novel surgical technique for iridodialysis repair using an iris retractor segment and report its clinical results.

Methods: Fifty-three eyes of 53 patients who underwent iridodialysis repair using an iris retractor segment were enrolled in this retrospective study. Data recorded from patient files consisted of age, sex, degree of iridodialysis, surgical techniques, number of segments used, preoperative and postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), complications, and follow-up time.

Results: Mean follow-up time was 34.4 months. The subjects included 29 men (54.7%) and 26 women (45.3%), and the mean age was 56.6 ± 14.0 years. According to the degree of iridodialysis, the patients were divided into Group 1 (60°-89°, n = 19) and Group 2 (90°-270°, n = 34). During the iridodialysis repair for Group 1, a single segment was sufficient; however, in Group 2, one segment was used in 18 eyes (52.9%), two segments in 15 eyes (44.1%), and three segments in one eye (2.9%). The pre- and postoperative last control CDVA value in Group 2 was significantly lower than in Group 1. The pre- and postoperative IOPs for Group 2 were significantly higher than Group 1.

Conclusion: Iridodialysis repair using an iris retractor segment is a minimally invasive technique and found to be safe and effective. It will be a good option for patients with large iridodialysis, as it avoids excessive surgical manipulations and prolonged surgical time.
