Objective: To investigate the clinical features of external oblique A sign and the effect of surgical correction. Methods: Thirteen patients in 18 patients underwent oblique muscle weakening surgery and horizontal muscle surgery. Five patients underwent simple horizontal muscle surgery. The preoperative and postoperative eye position, oblique function and binocular vision were observed. Results: Upper oblique weakening surgery and corresponding rectus abdominis shortening surgery for most of the external oblique A levy correction effect best. Conclusions: Oblique oblique muscle function is the main reason for exocrine A syndrome. Outside oblique A levy surgery is mainly on the weakened + rectus muscle strengthening surgery
