Eye convergence insufficiency is a condition in which the eyes are unable to turn inwards when a person looks at a nearby object. This common eye condition affects approximately 8 out of 10 people worldwide.

We know that the eyes are a direct conduit into the brain and are formed from brain tissue. We also know that convergence disorders creates eye strain and fatigue. Could this be linked to migraines? We think so! The eyes can play a direct role in the occurrence, frequency and types of headaches you get.

We’ve all heard of hand/ eye coordination but rarely do we hear of  body/eye coordination.  Osteopathic lesions and subluxations encountered are often caused by the body adapting to a dysregulated sensor. As such, a convergence defect will immediately result in a homolateral tilting of the shoulder and pelvis.

Two week ago, a patient by the name of Sandye came into Posturepro’s office regarding her constant struggle with headaches. She remembers her headaches beginning at the age of three and as far as she is concerned, they have affected her life almost every day. Today she is a regular at the migraine clinic here in Montreal (Clinique de la migraine de Montréal). Her migraines come in cluster episodes and can last anywhere from a week up to a month.

Sandye has tried to take control of the problem by consulting many specialists and neurologists who have prescribed her everything from painkillers (verapamil, zomig) and cortisone shots to help alleviate the symptoms. All have failed! Up to date, Sandye has spent a grand total of $20,000 trying to fix her condition.

After correcting Sandye’s hypoconvergent eye and posture she has reported being free of headaches and impressive changes have been remarked with her overall convergence.  The aim of our treatment is to “workout” the oculomotor muscles, training both eyes to function symmetrically as opposed to individually.


Convergence defects probably account for a great number of idiopathic vertigo, and the fact of having perfect vision in no way eliminates the possibility of having a convergence disorder or heterophoria.  Posturologists are trained to identify convergence disorders and can cure up to 85% of migraines in just one consultation.

Disturbances of the eye can be divided into two groups. Primary and secondary causes.

Primary causes

  • Cranial traumas
  • Cervical sprains
  • Convulsion
  • Meningitis
  • Meningitic syndromes
  • Cerebrovascular disease
  • Epilepsy
  • Certain auto immune disease
  • Spinal fractures
  • Fetal distress
  • Congenital hereditary disorders.

Secondary causes

  • Occlusion defects
  • Hepatitis
  • Antidepressants (tricyclic and non tricyclic).

If you are experiencing any of the below symptoms, chances are that until now, you are a victim of an undetected convergence disorder.

  • Travel sickness
  • Headaches
  • Heaviness in head
  • Spinal Strains
  • Single joint pain
  • Short leg
  • Astenia
  • Memory problems
  • Decreased sports performance
  • Dysgraphia
  • Agoraphobia
  • Redness of the eye
  • Personality issues in children
  • Blurred vision
  • Diplopia
  • Epilepsy
  • Difficulty to focus on an object for a long period of time
  • Sensation of sand in eyes
