In reading several recent posts I have seen a common theme of folks describing untreated visual symptoms that developed after their TBI. I experienced something similar and was diagnosed with a condition called Vertical Heterophoria (VH). It is not a well known or frequently recognized condition and is often missed altogether or miss diagnosed as something else; quite often as inner ear related vertigo. The info I can give here is very brief and I encourage anyone who thinks they may be afflicted with this condition to do further research and consult someone who is familiar with diagnosing it. I found my Doctors, who specialize in VH, by dumb luck when the hospital referred me to them for follow up after I was discharged. The Dr. almost immediately said "It's not your ears; it's your eyes." So, VH, or Binocular Vision Dysfunction, is a condition where one eye sees the image higher than the other eye. It's most common causes are; your born with it, HEAD TRAUMA, stroke, other neurological disorders. The most common symptoms are: headache, neck, upper back, shoulder and face pain, eye fatigue and pain, head tilt, balance and coordination problems, unsteadiness while walking, nausea, drifting to one side,(symptoms are similar to those seen in patients with MS, sequela of a stroke, an inner ear disorder or Menieres Disease), reading problems such as problems with comprehension, losing your place on the page, skipping lines or words, forgetting what you just read and having to re-read it several times. Psychological symptoms include feeling overwhelmed or anxious when in large contained spaces like malls or big box stores, feeling overwhelmed or anxious in crowds or while driving (symptoms similar to those seen in patients with anxiety or agoraphobia). And of course visual symptoms, which can include blurred vision, double or overlapping vision, shadowed vision (symptoms similar to those seen in patients with MS); light sensitivity, difficulty with glare or reflection. As long as this post is it barely grazes the surface of VH symptoms and related issues. Once I was treated it helped a lot. If anyone wants more in depth info feel free to send a PM.
