Symptoms of BVD

BVD can severely impact people of all ages. Children with BVD often struggle with reading in school, hand-eye coordination, playing sports, and car sickness. This condition often leads to misdiagnoses of ADHD, dyslexia, and migraines in children. Adults with BVD regularly experience headaches, daily anxiety and dizziness, and can be severely limited from doing normal tasks or succeeding in the workplace.

 

The symptoms of BVD are wide-ranging and not often recognized by traditional eye doctors. Those who specialize in treating BVD often organize the symptoms into groups based on how they impact patients:

Neck pain and/or shoulder and back pain

Struggles to walk in a straight line

Head tilt

Clumsy, bumping into doorways and people they are walking next to

What causes BVD?

The condition can be caused by facial asymmetry similar to adults, or it can be caused by a concussion or head injury, such as from a soccer game or falling while riding a bike. Some research suggests that at least 20% of adults experience some symptoms of BVD that may be interfering with their everyday lives. Someone you know may be suffering from binocular vision dysfunction and not even realize it. Exactly why some people develop BVD and others don’t often isn’t clear.

 

Early research has found that BVD can be genetically inherited and run in families, most often from mother to daughter. In other clinical research, there is a direct correlation between head injury or concussion and the onset of BVD symptoms. There is also a connection between BVD and acquired brain injuries caused by a stroke, Lyme disease, COVID-19, and Mono (Mononucleosis).

Can BVD be misdiagnosed?

Yes, BVD symptoms are often mistaken for a number of other conditions since many medical and eye doctors don’t know how to screen for and diagnose BVD. Patients are regularly but mistakenly told they have one of the following conditions, while in reality BVD is the main cause of their symptoms: 

 

■  Agoraphobia

■  Anxiety / Panic disorders

■  ADD / ADHD

■  Cervical misalignment

■  Meniere’s Disease

■  MS (Multiple Sclerosis)

■  Reading Comprehension Issues

■  Sinus problems

■  Psychogenic dizziness / Chronic Subjective Dizziness

■  BPPV (Benign Paroxysmal Positional Vertigo)

■  PPPD (Persistent Postural-Perceptual Dizziness)

■  Vestibular Migraine / Migraine Associated Vertigo (MAV)

■  TMJ (temporomandibular joint) disorders
