PURPOSE
The purpose of the study was to measure the effect of rim-off deep lateral decompression for Graves orbitopathy on the lateral rectus muscle path and oculomotor balance.
METHODS
Retrospective analysis of the medical records and pre- and postoperative computed tomography scans of 34 orbits of 23 patients who underwent deep lateral decompression alone. The oculomotor balance of these 23 patients was measured with the alternate cover test and prisms before and after surgery. Bezier functions were used to measure the postoperative path of the lateral rectus in all decompressed orbits.
RESULTS
Deep lateral decompression induced a curvilinear deformation of the lateral rectus. There was no significant correlation between the position of the point of maximum muscle displacement and the size of the residual lateral wall. The changes in the lateral rectus path had no adverse effects on the oculomotor balance of the patients.
CONCLUSIONS
The location of the curvilinear deformation of the lateral rectus does not depend on the residual segment of the lateral wall. The changes of the lateral rectus path have no deleterious effect on the oculomotor balance.
目的
本研究旨在测量Graves眼病眶缘外深层减压术对眼外直肌走行及眼球运动平衡的影响。
方法
对23例仅接受深层外侧减压术患者的34个眼眶的病历及术前、术后计算机断层扫描进行回顾性分析。通过交替遮盖试验和三棱镜测量这23例患者手术前后的眼球运动平衡。使用贝塞尔函数测量所有减压眼眶中眼外直肌术后的走行。
结果
深层外侧减压术导致眼外直肌呈曲线形变形。肌肉最大位移点的位置与剩余眶侧壁大小之间无显著相关性。眼外直肌走行的改变对患者的眼球运动平衡无不良影响。
结论
眼外直肌曲线形变形的位置不取决于眶侧壁的剩余部分。眼外直肌走行的改变对眼球运动平衡无有害影响。
