The loss of vision may affect one or both eyes.
Causes of vision loss after trauma associated damage to the eye:
(1) corneal damage
(2) something covering the cornea (blood, foreign body, other)
(3) traumatic cataract
(4) traumatic luxation of the lens
(5) acute angle-closure glaucoma
(6) hyphema
(7) vitreous hemorrhage
(8) traumatic retinal edema and/or hemorrhages
(9) retinal detachment
(10) occlusion from central retinal artery or vein
Causes of vision loss after trauma due to damage of the visual pathways:
(1) avulsion of the optic nerve
(2) indirect trauma to optic nerve or chiasm
(3) intracranial interruption of visual pathways
(4) cortical blindness from hematoma or ischemic injury
Other causes:
(1) strong emotion (hysteria, PTSD, etc)
