Vertical Heterophoria Syndrome (VHS)
I am currently dealing with a client who sustained a head injury and whose doctors are trying to rule out Vertical Heterophoria Syndrome (VHS).
This is an eye alignment condition. Those who suffer from VHS are over-working their eye muscles to maintain vertical eye alignment. This leads to eye muscle strain and fatigue, which causes many different symptoms, including:
Dizziness
Lightheadedness
Nausea
Unsteadiness
Drifting While Walking
Poor Coordination
Poor Depth Perception
Motion Sickness
Headaches
Neck Ache
Head Tilt
Anxiety From Dizziness
Feeling Overwhelmed or Anxious in Crowds or Large Spaces
Light Sensitivity / Glare
Double Vision
Shadowed/Overlapping Vision
Difficulty with Reading & Reading Comprehension
My wife was just diagnosed with this today. We went to http://www.visionspecialistsofbirmingham.com/ -- it's in Michigan, but maybe your guy needs a second opinion by someone who is trained in Vertical Heterophoria -- They did about a 3 hour exam with my wife and were able to offer her a noticeable difference before she left ... unfortunately, she has to wait for glasses for a couple days now so her symptoms returned.
