眼球水平运动中视神经及视网膜形态改变研究进展

Advances in the study of morphological changes of optic nerve and retina in horizontal eye movement

视盘及视网膜功能受眼压影响所产生的损伤是导致不可逆性视力下降的主要原因之一。除了眼压的影响外,有研究发现眼球水平运动,即水平内转和外转运动对视盘及周围视网膜组织产生机械性压力和牵拉力,从而对组织产生影响,且这种改变与水平转动的角度、速度以及年龄等因素有一定的相关性。研究发现眼球水平运动可引起视盘鼻侧和颞侧视盘,以及周围视网膜及脉络膜结构的改变,而这种改变在不同年龄人群中存在一定差异。本文就目前眼球水平运动对视神经及视网膜形态的影响的研究进行综述,以期为临床相关疾病的治疗提供一些有益的线索。

The impairment of optic disc and retinal function caused by intraocular pressure is one of the main causes of irreversible visual impairment.In addition to the effects of intraocular pressure,studies have found that ocular adduction and horizontal abduction movements affect the optic disc and surrounding retinal tissue,which result in mechanical pressure and traction having influences on tissue and this change is related to the rotation angle,speed,and age,etc.Studies have found that horizontal eye movements can cause changes in the nasal and temporal sides of the optic disc,as well as the surrounding retinal and choroidal structures,and these changes vary among different age groups.This paper reviewed the current research on the effects of horizontal eye movements on the morphology of the optic nerve and retina,in order to provide some useful clues for the treatment of relevant diseases in clinical practice.
