Symptoms of Binocular Vision Dysfunction

Dr. Spokas specializes in the diagnosis and treatment of Binocular Vision Dysfunction. People suffering from these conditions have a small amount of vision misalignment not found on a routine eye exam.

Dizziness, lightheadedness and disorientation with varying degrees of frequency, from occasional episodes to daily awareness. Triggers to Dizziness include:
side to side head movement
up and down head movement
getting up quickly for a seated position
bending over to retrieve an object and getting up quickly
riding as a passenger in a car, especially in the back seat
going around curves while in a car
high speed expressway driving with fast moving vehicles passing on either side
Nausea
Motion sickness and car sickness, often since childhood.
Unsteadiness while walking. Develops a slower gait to feel steadier on feet and to avoid falling.
Falls often (with occasional breaks to bones) due to being unsure of their footing.
Drifts to one side while walking. Unintentionally moves in to someone else’s space while walking next to them. Feels like their midline or body center is shifted to one side. Walks in to door frames, edges of tables, corners of counter, etc., often with the same side of the body each time.
Please Note: These symptoms are similar to those seen in patients with MS, sequella of a stroke, inner ear disorder or Meneire’s Disease.

Headaches with varying degrees of intensity and location. Most common locations: forehead, temples, back of head.
Pain with eye movements.
A feeling of pressure and heaviness on top of the head.
Facial / “sinus” pain, pain in the jaw region.
Severe neck and shoulder discomfort due to an accompanying head tilt (frequently obvious). Neck pain described as a neck headache or neck migraine.
Please Note: These symptoms are similar to those seen in patients with sinus problems, migraines, TMJ problems, spinal misalignment issues.

Difficulties with stopping at traffic lights and stop signs and behind other vehicles because of problems with estimating distances. The signs seem to move due to the underlying dizziness. It can sometimes feel like the car is moving backward even though the foot is on the brake.
Images are seen moving in the peripheral vision that aren’t really moving.

Anxiety associated with being uncomfortable while driving in a moving vehicle. Concern that a dizzy episode will occur while they are driving, and that they will not be able to pull over to the side of the road to get to safety, before harming themselves or others.
Anxiety associated with being in a space with a tall ceiling (i.e. malls, grocery stores, big box stores). The multiple stimuli and detail in a large space can overload the visual system and trigger a dizzy episode with the resultant feeling of being overwhelmed.
Overwhelmed when in a large group of people.
Generalized anxiety, sometimes severe enough to cause suicidal ideation.
Please Note: These symptoms are similar to those seen in patients with agoraphobia or anxiety syndromes.

Rereading for comprehension / difficulty concentrating.
Skipping lines when reading. Losing their place while reading. Using their finger or a ruler as a guide to follow along on a line of print.
Words running together while reading.
Fatigue with reading.
Please Note: These symptoms are similar to those seen in patients with ADHD or a learning disability.

Fitful and restless sleep pattern. Aware of eye movement making them dizzy, even while trying to fall asleep, causing dizziness.
Often they sleep better when the room is completely dark, since the light will be seen through the eyelids, triggering visual vertigo.

Sensitivity to bright lights from misalignment of eyes causing an exaggerated amount of glare off of all surfaces.
Blurred vision, overlapping vision, double vision, shadowed vision.
Poor depth perception. Sometimes feeling uncoordinated since childhood, especially with sports like catching or hitting a ball (i.e., activities requiring keen hand-eye coordination).
Closing or covering an eye eases visual tasks (near or far)

Eye strain
Blurred distance vision
Blurred near vision

Feeling spacey.
Having difficulty concentrating when someone is talking to them, especially when it is for more than a couple of minutes.
Difficulty looking other people in the eyes for any prolonged period of time. It is made worse when the person is moving his/her hands or body, which can over stimulate the visual system and trigger dizziness.

The number and severity of symptoms are different for each person. Some people are disabled; others aren’t bothered much.

Many people with Traumatic Brain Injury (TBI) develop a small amount of eye misalignment from their injury that cause these symptoms.
