固定性内斜视比较罕见。它是由于内直肌僵硬、纤维化将眼球固定于内斜位。多为先天性,也有后天发生者,实际上是外直肌麻痹后,内直肌高度挛缩的后果,属于续发的。传统的治疗方法是将内直肌完全断腱或后退至赤道的后方,但由于内直肌异常挛缩紧张,手术效果不理想,易复发。我们以切断内直肌合并眶缘骨膜瓣转位,治疗固定性内斜视2例3只限,随访3个月至3年效果满意。手术方法:①麻醉:局部浸润麻醉。小儿可全麻。②右眼于2～4点钟,左眼于
Fixed esotropia is relatively rare. It is due to stiffness of the rectus abdominis, fibrosis will be fixed in the oblique eye. Mostly congenital, there are those who happen, in fact, lateral rectus paralysis, the consequence of a high degree of contracture of the rectus abdomen, are persistent. The traditional treatment is completely rectus tendon or retreat to the equatorial rear, but due to abnormal contraction of the medial rectus muscle tension, the effect is not satisfactory, easy to relapse. We cut off the rectus muscle with orbital marginal periosteal flap transposition, the treatment of 2 cases of fixed esotropia 3 limited, follow-up of 3 months to 3 years with satisfactory results. Surgical methods: ① anesthesia: local infiltration anesthesia. Children can be general anesthesia. ② right eye at 2 to 4 o’clock, left eye on
