RA (the most common disease cause) and Paget disease of the cervical spine can cause atlantoaxial dislocation or subluxation, basilar invagination, or platybasia. Metastatic tumors that affect bone can cause atlantoaxial dislocation or subluxation.
I suffered an accident with trauma to the face/eye (left side) a week ago. The worrying development has been flashes of light off to the side in my left eye only that have progressively become more frequent. They last a second or two and look like wavy flashes of light off to the far peripheral. I have had three eye examinations that have ruled out vitreous or retinal detachment, only have a black eye and subconjunctival hemorrhaging. CT scan shows no fractures, no brain damage, nothing.
