I had a 4 level cervical fusion C-3 thru 7 a little over 2 weeks ago with a long vertical incision on the right side of my neck. My right eye is droopy and the pupil is smaller and the vision is extremely weak. The surgeon dismissed it but I found this site discovering that it fits the description of Horner's syndrome. I am wondering if I should simply wait to see if it improves or seek advice and if so, from an optomologist? I also was surprised that this was not discussed as a possible side effect. Any treatments anyone is aware of or suggestions would be greatly appreciated. Promise to post outcome when and if improvements come about.
