Abstract

Objective: The study evaluated the relationship between the amount of inferior rectus muscle (IRM) recession and subsequent lower eyelid (LE) retraction in patients with thyroid eye disease (TED).

Material and methods: The study included 40 patients (40 eyes) with inactive TED and IRM involvement confirmed by multislice computed tomography of the orbits. All patients underwent IRM recession of 4.5 to 9 mm. Before and after surgery (on days 1 and 7, at 2-3 months, and at 6 months), LE position was photoregistered with the head and gaze in the primary straight position. The distances from the center of the pupil to the lower eyelid margin (MRD2) and from the lower limbus to the eyelid margin (MLD2) were measured using Adobe Photoshop software, with pixels converted into millimeters. The data were analyzed using SPSS software (Statistical Package for the Social Sciences, version 2.0).

Results: According to the obtained data, lower eyelid position changed on day 1 in 100% of cases, and MRD2 and MLD2 values increased compared with preoperative values. LE retraction significantly increased over time in the postoperative period, reaching maximum values by the third month, further changes were minimal. Analysis of data on day 1 after surgery showed no significant correlation between the amount of IRM recession and the degree of LE retraction. However, analysis at 3-6 months revealed a weak positive correlation: the greater the amount of IRM recession, the higher the degree of LE retraction by this time point.

Conclusion: The degree of LE retraction increases during the postoperative period and reaches maximum values by 3-6 months. After LE position stabilizes at 3 months or later, a weak positive correlation is observed between the amount of IRM recession and the degree of LE retraction. However, its severity appears to depend not only on the amount of recession but also on a complex of individual anatomical features and the degree of tissue involvement in the pathological process.

甲状腺眼病患者下直肌收缩量对下眼睑位置的影响。

目的：探讨甲状腺眼病（TED）患者下直肌（IRM）收缩量与下眼睑（LE）后缩回的关系。材料和方法：本研究包括40例（40只眼）非活动性TED和IRM受累的患者，经眼眶多层计算机断层扫描证实。所有患者的IRM均退行4.5 - 9mm。术前、术后（第1天、第7天、2-3个月、第6个月），LE位置与头部和凝视在主直位照相记录。使用Adobe Photoshop软件测量瞳孔中心到下眼睑边缘（MRD2）和下眼睑到下眼睑边缘（MLD2）的距离，像素转换为毫米。使用SPSS软件（Statistical Package for The Social Sciences, version 2.0）对数据进行分析。结果：根据获得的数据，100%的病例下眼睑位置在第1天发生变化，MRD2和MLD2值较术前升高。术后LE内收明显增加，在第3个月达到最大值，进一步的变化最小。术后第1天的数据分析显示，IRM收缩量与LE内收程度之间无显著相关性。然而，3-6个月的分析显示出微弱的正相关：IRM衰退的程度越大，到这个时间点，LE的收缩程度越高。结论：术后LE内收程度增加，3 ~ 6个月达到最大值。在LE位置稳定3个月或更晚后，观察到IRM衰退量与LE缩回程度之间存在弱正相关。然而，其严重程度似乎不仅取决于衰退的程度，还取决于个体解剖特征的复杂性和病理过程中组织的参与程度。
