目的　了解上斜肌止端前缘的解剖部位。方法　在 1 9例DVD病人 ( 2 4眼 )上直肌后徙手术中对上斜肌的止端进行测量、记录。结果　上斜肌止端前缘距上直肌止端距离为 4 0～1 0 0 0mm ,水平方向从偏鼻侧 4 0mm到偏颞侧 2 0mm。结论　上斜肌止端解剖部位变异大 ,在行上直肌和上斜肌手术时应该注意 Objective To understand the anatomic site of the anterior oblique superior oblique end. Methods The ends of the upper oblique muscle were measured and recorded in the rectus muscle reimplantation surgery in 19 DVD patients (24 eyes). Results The distance between the anterior edge of superior oblique muscle and the superior rectus muscle was 40 ~ 100 mm, and the horizontal direction was 40 mm from the nasal side to 20 mm of the temporal side. Conclusions The anterior oblique anatomical site of varus is large, so it should be noted in the rectus abdominis and upper oblique muscle operation
