Abstract

Purpose

The aim of this study was to investigate the morphometric development of the extraocular muscles in the fetal period and to create a modified Tillaux spiral.

Methods

We dissected 157 fetal eyes (82 right eyes, 75 left eyes) obtained from 79 fetuses (46 boys, 33 girls) between 13 and 40 weeks of gestation. The tendon widths of the extraocular muscles and the distances of the tendon attachment sites to the limbus were measured. Tillaux's modified spiral was created.

Results

In addition to the rectus muscles, we added tendon widths and tendon–limbus distances of the upper (SO) and lower (IO) obliques to the modified Tillaux spiral. When tendon widths were compared between genders, no statistically significant difference was observed. When tendon widths were compared between the sides, it was determined that SO was more in the left eye, whereas other extraocular muscles were more in the right eye. There was no statistically significant difference between genders when the distances of tendon attachment sites to the limbus were compared. There was no statistically significant difference in SO and IO values between the sides. There was a statistically significant difference in the rectus muscles and this difference was found to be higher in the right eye.

Conclusion

We think that the findings obtained will contribute to disciplines such as fetopathology, obstetrics, ophthalmology and plastic surgery and to future studies on this subject.

胎儿时期眼外肌的发育

目的：本研究旨在研究胎儿时期眼外肌的形态发育，并创建一个改良的Tillaux螺旋。方法：我们解剖了79个妊娠13至40周的胎儿（46个男孩，33个女孩）的157只胎儿眼（82只右眼，75只左眼）。测量了眼外肌腱的宽度以及腱附着点到眼球边缘的距离。结果除直肌外，我们还将上（SO）斜方肌和下（IO）斜方肌的腱宽度和腱-肢距离添加到修正的 Tillaux 螺旋中。当比较不同性别的肌腱宽度时，没有观察到显著的统计学差异。当比较两侧肌腱宽度时，发现左眼的斜方肌更多，而右眼的其他眼外肌更多。在比较肌腱附着点到角膜缘的距离时，男女之间没有明显的统计学差异。两侧的 SO 值和 IO 值在统计学上没有明显差异。直肌的差异在统计学上有显著意义，而且右眼的直肌差异更大。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
