概括
在甲状腺眼病 (TED) 后,新出现的双视 (双视) 是常见的,但通常是暂时的. 由于轨道变化和肌肉调整,大多数患者在一年内恢复.
科学领域:
- 眼科医生 眼科 眼科
- 内分泌学 在内分泌学.
- 手术研究的研究.
背景情况:
- 甲状腺眼病 (TED) 可以导致轨道变形和视力问题.
- 低中轨道壁减压是一种手术程序,以缓解与TED相关的轨道并发症.
- 手术后的双眼视是TED患者的轨道减压手术的已知风险.
研究的目的:
- 在TED患者中,研究下介质轨道壁减压后新发性双眼视的发生率,临床过程和机制.
- 通过CT成像,将双眼视的结果与轨道结构和眼外肌肉对齐的定量变化相关联.
- 了解影响双眼视的解决或在一年的随访期内持续存在的因素.
主要方法:
- 回顾不活跃的TED患者的回顾性审查,这些患者经历了下介质轨道壁减压.
- 纳入标准:在1个月后出现新的双眼视,并完成1年的随访.
- 使用戈曼分数和HESS测试评估双眼视;对轨道体积和眼外肌肉偏差角度进行定量CT分析.
主要成果:
- 在手术后1个月,35%的患者出现了新发性双眼视.
- 显著的大多数 (73.2%) 新型双眼盲患者在1年的随访期内完全康复.
- 康复的患者在1年内表现出 significant 的轨道体积减少和改善的眼外肌肉对齐,与持久性双眼盲患者相比.
结论:
- 在TED中下介轨道壁解压后新发的双眼视通常是短暂的,大多数病例在一年内消失.
- 轨道重塑和随后的眼外肌肉调整似乎是驱动双眼视解决的主要机制.
- 持续的双眼视可能与缺乏显著的轨道体积变化或肌肉对齐改善有关.

Muscles of the Eye
4.9K
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

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...
