挫伤性视神经病变主要是在外力的作用下,强大的冲击力及反冲力使视神经管内视神经发生震荡,引起神经纤维血管源性的组织水肿,纤维的疏松、变性等,造成视功能的低下。早期眼底多正常。随着组织水肿的消失,瘢痕的修复,眼底视盘颜色逐渐变淡,此时希诊贻误治疗机会。对于较重的损伤(如矫正视力<0.1),依据视力,视野、瞳孔的光反应、电生理及影像学等方面的检查,早期即可确诊。但对轻度损伤者(如矫正视力≥0.2),往往不易确诊。另
Contusion optic neuropathy is mainly under the action of external forces, a strong impact and recoil force to optic nerve canal in the optic nerve concussion, causing nerve fiber vascular tissue edema, loose fibers, degeneration, resulting in visual function is low. More normal early fundus. With the disappearance of tissue edema, scar repair, fundus disc color gradually fades, this time Chi Chi delaying the treatment of opportunities. For severe injuries (such as corrected visual acuity <0.1), based on visual acuity, visual field, pupil light response, electrophysiology and imaging aspects of the examination, early diagnosis. However, mild injury (such as corrected visual acuity ≥ 0.2), often difficult to diagnose. another
