What Causes Strabismus?

To know what causes strabismus, it is essential to make a distinction between the various kinds of strabismus. Essentially the strabismus causes may be because of issues in the eye muscles power like paralysis or unequal pulling of muscles on one side of the eye, or because of a brain problem that hinders the coordination of the eyes.

First of all, it is currently unclear what causes strabismus among children. However, researchers think that it is hereditary because it is frequently seen to run among families. In other words, an individual with a family member that has it has an increased chance to have a child with strabismus.

Another major strabismus causes is that it could be a coping mechanism of the eye for another vision problem like farsightedness. Far sighted persons cannot properly perceive near objects and as a result, the eyes turn inwards.

Intermittent strabismus is a form of strabismus wherein the eye does not always turn, as it only turns because of specific stimulus like sickness or stress. The strabismus causes for this kind of condition is a vision issue called convergence insufficiency. A lot of people experience it and it can also cause double vision, blurred vision, headaches, and eyestrain.

On the other hand, adults can have strabismus due to eye or blood vessel damage. This could be due to medical conditions like muscle and nerve disorders, cataract, stroke, Graves’ disease, eye tumor, and blindness. Blindness often results to the gradual outward turning of the eye thus the strabismus. Diabetes can also cause strabismus among patients. It is because the disease limits the blood supply to the eye muscles, causing the eyes to squint.

Additionally, some neurological conditions can also become strabismus causes. Some of these conditions are Down’s syndrome, hydrocephalus, premature birth, brain tumors, and Cerebral Palsy. In addition, acquired or adult strabismus may also be a result of untreated or unsuccessfully treated childhood strabismus.
