Diplopia (double vision) following traumatic injury may be due to a number of conditions.
Causes of post-traumatic diplopia include:
(1) transection, avulsion, hematoma or contusion of extraocular muscles
(2) avulsion of the pulley of the superior oblique muscle
(3) decompensation of a preexisting ocular phoria
(4) hematoma in the orbit
(5) orbital fracture
(6) orbital or intracranial damage to the third, fourth and/or sixth cranial nerve with palsy
(7) whiplash injury
Causes of post-traumatic monocular diplopia (double vision affecting 1 eye) include:
(1) subluxation of the lens
(2) detachment or edema of the macula
