晶状体悬韧带的研究进展

Research Progress of Suspensory Ligaments of Lens

晶状体悬韧带是连接着睫状体和晶状体的带状纤维组织,凭借纤维组织间共同张力,将晶状体悬挂于视轴解剖位置。晶状体悬韧带是一个复杂的细胞外纤维系统,在生理状态下是透明的,难以观测。临床医生经常通过裂隙灯显微镜检查间接观察悬韧带异常,如虹膜震颤和周边浅前房,当悬韧带出现部分或全部断裂时,通常会伴随晶状体不全脱位或全脱位。然而,一些临床症状可能是隐匿性或轻微的,在临床上很容易被忽视。因此对于接受眼科手术的患者,术前仔细评估晶状体悬韧带情况是十分必要的。本文就晶状体悬韧带解剖结构、功能及悬韧带异常的机制及治疗综述如下。

The suspensory ligaments of lens are a banded fibrous tissue connecting the ciliary body and the lens. By virtue of the common tension between the fibrous tissues, the lens is suspended in the an-atomical position of the optic axis. The suspensory ligaments of lens are a complex extracellular fi-ber system, which is transparent and difficult to observe under physiological conditions. Clinicians often observe zonule abnormalities indirectly through slit-lamp microscopy, such as iris tremor and peripheral superficial anterior chamber. When the suspensory ligaments of lens are partially or completely broken, it is usually accompanied by incomplete dislocation or total dislocation of the lens. However, some clinical symptoms may be insidious or mild and can be easily overlooked clini-cally. Therefore, it is necessary to carefully evaluate the suspensory ligaments of lens before surgery for patients undergoing eye surgery. In this paper, the anatomical structure, function, mechanism and treatment of zonule abnormalities are summarized as follows.
