概括

扩散张力成像 (DTI) 显示了眼外肌肉 (EOM) 的微妙变化. 减少的扩散度指标可能表明EOM中的肌肉收缩和更薄的纤维结构.

科学领域:

眼科医生眼科眼科
神经学神经学
医疗成像医学成像

背景情况:

视是一种常见的视,包括眼睛向内转动.
眼外肌肉 (EOM) 的微观结构变化有助于食热病理生理学.
扩散张力成像 (DTI) 提供了一种非侵入性方法来评估组织微观结构.

研究的目的:

评估扩散张力成像 (DTI) 度量在表征水平眼外肌肉 (EOM) 的微观结构异常在患有食otropia的患者中的实用性.
为了比较DTI参数,以热带病患者和健康对照.

主要方法:

常规的MRI和DTI在6名同时患有食热症的患者,5名单边的患者和2名健康志愿者中使用3TMR扫描仪进行.
分数异构性 (FA),平均扩散性 (MD),轴向扩散性 (AD) 和辐射扩散性 (RD) 测量了中间和侧直肠肌肉.
在患者组和对照组之间比较了DTI指标.

主要成果:

与单边倒性患者相比,同时发生的食热症患者的中直肠MD和RD显著更高.
与对照组相比,这两组眼患者在侧直肠肌肉中显著减少了MD和AD.
与健康对照人群相比,同时患有食otropia的患者表现出中间直肠MD和侧直肠AD的减少.

结论:

DTI是一种可行的技术,用于评估EOM组织特征.
观察到眼睛位置变化对DTI参数的微妙影响.
在中间直肠肌肉中减少的MD和RD表明ESOTROPIA中EOM纤维结构的潜在收缩和稀薄.

Muscles of the Eye

Muscles of the Eye

The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
