To know what causes strabismus, it is essential to make a distinction between the various kinds of strabismus. Basically the strabismus causes can be due to a disorder of the brain in coordinating the eyes, or because of problems in one or more of the relevant eye muscles power such as paralysis or unequal pulling of muscles on one side of the eye.

First of all, what causes strabismus in children is still unidentified. However, there scientists believe that it is hereditary as it is commonly seen to run in families. In short, a person with a known family history of the condition has an increased probability to have an offspring 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 people are unable to perceive near objects that results in to the turning of the eyes inwards.

Intermittent strabismus is a kind of strabismus wherein the eye does not turn constantly, as it only does during stressful situations or because of sickness. The strabismus causes for this type of condition is a vision problem known as convergence insufficiency. A lot of people experience it and it can also cause double vision, blurred vision, headaches, and eyestrain.

Meanwhile, adults may have strabismus because of eye or blood vessel damage. This can be brought about by other conditions like blindness, eye tumor, Graves disease, stroke, cataract, and various muscle and nerve disorders. Blindness often results to the gradual outward turning of the eye thus the strabismus. Diabetes may also cause strabismus among people. This is due to the lessened blood supply to the eye muscles, leading to the squinting of the eyes.

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.
