I am not sure what you mean by eyes constricted—if this means you have tunnel vision or constricted vision then this can be due to optic nerve damage caused by glaucoma, high internal eye pressure, retinal detachment, occlusion of blood supply as in eye stroke
, optic neuritis, and optic nerve edema. Tunnel vision is also possible after a
history of head injury, concussion, brain damage and stroke.
Hence it is important to first consult an eye specialist and then a neurologist.
