The Connection Between Vision and Posture: How Osteopathy Can Help

Ocular Convergence

Ocular convergence refers to the movement of the visual axes when shifting from distant vision to near vision. Convergence can be voluntary or reflexive and involves the combination of three mechanisms: fusion, accommodation, and tonic convergence.

Correlation Between Vision and Posture

The muscles of the eyes, neck, and entire muscular system are connected. When the eyes move, the muscles in the nape of the neck also contract to move the head, allowing one to follow the object being observed. Vision and posture are two mechanisms within a single perceptual process; an alteration in our vision leads to a modification of posture and vice versa.

Implications

If we cannot focus on something while reading or working on the computer, we tend to unconsciously move our eyes away from the page or monitor, straining the neck. Furthermore, a compensatory mechanism limits the rotation of the head on the side where the eye converges less and raises and pulls back the left shoulder in right-handed individuals, and the right shoulder in left-handed individuals. The neck muscles, as we have seen, are closely connected to the ocular muscles, so tension in these muscles can, for example, lead to focusing problems.

What Can an Osteopath Do?

In cases of convergence and posture defects, the osteopath works synergistically with a specialist, such as an ophthalmologist, to resolve the problem at its root. During the consultation, the osteopath checks for dental occlusion issues that might influence the movements of the skull and cervical spine. The ultimate goal of osteopathic treatment is to restore the patient's postural balance and horizontal vision.

Remember, osteopathic treatment should always be carried out in collaboration with and under the supervision of a medical professional to ensure comprehensive care and the best outcomes.
