Adjustable suture surgery via parks cul-de-sac approach for intermittent exotropia

Abstract

Objective To observe the ophthalmologic outcome of adjustable suture surgery via parks cul-de-sac approach for intermittent exotropia. Methods Review of 37 patients with intermittent exotropia treated with adjustable suture technique via parks cul-de-sac approach. Postoperatively, they were followed up for 3～8 months. Results (1)Ocular alignment: eleven of the 37 patients were not initially in desired alignment, two patients showed an undercorrection and nine overcorrection. In the first 24 hours after surgery,eleven patients had adjustment, they were all in desired alignment after adjustment. Final ocular alignment: of the patients without adjustment, two were extropic and one esotropic. Of patients adjusted, three were extropic. Thirty-one of the 37 patients were orthotropic.(2)Healing of conjunctival incision: all conjunctival wounds were healed 5～8 days after surgery. There was no obvious conjunctival scarring in lid fissure. (3)Postoperative complications: five patients had local swelling chemosis above suture tie and cured with topical corticosteroid. We did not encountered any muscle slippage,infection and scleral perforation Conclusion In the first 24 hours after surgery, adjustable suture technique with parks cul-de-sac approach is an effective method for ocular realignment in patients with intermittent exotropia and disadvantages of limbal conjunctival approach are avoided.
