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

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.
