RESUMO
Objective To evaluate the modified foruix-based technique with Guyton hook as an approach for the treatment of children with horizontal strabismus.Methods The clinical data of 128 patients (170 eyes) who underwent horizontal strabismus surgery between January 2014 and June 2017 were retrospectively reviewed,including 60 males and 68 females.The mean age was 1.5-17.0 (6.5 ± 1.6) years.All procedures under general anesthesia were performed using the modified fornix-based conjunctival incision with Guyton hook,and the follow-up period was 6 to 12 months.The clinical and cosmetic outcomes of strabismus surgery,the complications and interventions related to the incision were assessed.Results At 3 months after surgery,orthophoria with excellent cosmetics was achieved in 119 patients (93％) with the deviation ≤ ± 10△.Together 102 eyes (60％) had no intraoperative suture.Moreover,the incision was sutured with one stitch in 45 eye (26.5％),in 20 (11.8％) with 2 stitches,and in 3 (1.8％) with 3 stitches.During the follow up period,there was no severe intraoperative or postoperative complications.The swelling and redness of conjunctiva recovered quickly.Patients' discomfort was alleviated in a few days after the surgery.No oblivious scarring was found along the incision lines.Conclusion The modified fornix-based approach with Guyton hook is an effective and safe method for minimal incision surgery in children with horizontal strabis.
