Horner's syndrome

[Ronbus]

I had an anterior cervical fusion two months ago.  The morning after I was told I had Horner's syndrome as a result of pressure put on the sympathetic nerve in the neck during surgery and it should resolve in a few weeks.  The eye lid has gotten a little better, the pupil is still constricted.  As mentioned by another person on this forum, both the pupil and the eye lid get worse when I am tired and I also have a vision change that also gets worse as I tire.  The vision is like seeing at two different depths, it makes it very hard to read.  My question is because the other person that wrote to this forum was told that Horner's syndrome does not cause vision changes.  Is that still true (the question was from 1998)?  If it is true, is there somethings else involved in the surgery that would cause it?  I had 20/20 vision last year at my eye exam and no changes until right after surgery.

Hi.  Horner's syndrome should not have an effect on visual acuity, but it does affect the constricting of the pupils which may affect near vision or accomodation.  It is very hard to ascertain the exact cause for your decrease in visual acuity especially that it is unlikely that there can be damaged nerves pertaining to the eyes that may have been damaged during the spine surgery.  I suggest you continue to monitor your eye problems with your opththalmologist, the symptoms may still be partly explained by the pupil problems and hopfully these will all resolve in due time.  regards and God bless.
