Binocularity Following Surgical Correction Of Large-angle Intermittent Exotropia In Adults

Objective:To evaluate the change in binocularity sensory status in adults with large-angle intermittent exotropia before and after surgery.Methods:Consecutive patients with large-angle intermittent exotropia in adults were enrolled.Binocularity sensory status was examined with Worth 4-dot test and synoptophore.Near stereopsis was tested with Titmus.Distance stereopsis was tested with synoptophore.All patients were completed the examinations before and 2 weeks,8 weeks,half a years after strabismus surgery.Results:Central fusion was significantly improved postoperatively 2 weeks and 8 weeks(P <.05).Near stereopsis was no significantly impoved postoperatively 2 weeks(P=0.019)and it was improved obviously after 8 weeks.Binocular visual function with tested by synoptophore was restored postoperatively 2 weeks and 8 weeks(P <.05).Conclusion:The operation can relieve the patient’s peripheral fusion and improve the near stereopsis.The binocular visual function was improved in 2 weeks after surgery for adult patients with large-angle intermittent exotropia,and this period is plastic.Surgery of patients with large-angle intermittent exotropia can be delayed after being treated with anesthesia if they have a good binocularity sensory status.
