That's pretty obvious!! The most common cause of posterior vitreous detachment is normal aging changes but severe trauma as you describe can cause a traumatic PVD. Moreover the symptoms you describe are very troubling and I strongly suggest you see an ophthalmologist as soon as possible to see if you have a retinal detachment, retinal tear, vitreous hemorrhage or a type of retina trauma called a retinal dialysis.
Additionally if you have any systemic symptoms you should see your personal physician as that injury can cause a concussion, skull fracture, subdural hematoma and other severe injuries.
I hope you have also reported this assault to the police.
