The symptoms of strabismus are somehow clear-cut and you can ordinarily tell is a person has it by just observing their eyes. The condition is also called wall eye, cock eye, boss eye, crossed eye, lazy eye, and squint. It is marked by eyes that are not correctly aligned with each other, because of lack of coordination of the extraocular muscles that manipulates the movement of the eye. Here are the symptoms of strabismus that can help you diagnose if a person has the condition.
One of the symptoms of strabismus is that the eyes are incapable of looking in the same direction simultaneously. This is probably due to the fact that the extraocular muscles are weak hence incapable of coordinating the movement of the eyes. This can lead to difficulties in using binocular vision which is essential because it provides a wider field of view and is utilized in depth perception.
One more symptoms of strabismus is that the eyes are not able to move together. The direction of the eyes is based on the type of strabismus that the person has. Estropia also known as crossed eyes is the most typical type wherein one eye turns inward. One more kind is exotropia or walleye wherein one eye turns outwards towards the temple. There is also the uncommon forms hypertropia or vertical deviation wherein the eye turns upward towards the eyebrow, or hypotropia wherein the eye turns downward.
Because of the impaired vision that is due to lack of binocular vision, the other symptoms of strabismus include closing one eye in the bright sunlight, tilting of the head to look in an object, and bumping into things.
People afflicted with strabismus are incapable of using both their eyes concurrently so they have to close their eyes. They also are incapable of judging the depth of an object visuall and that is why they have to tilt their heads to do so. And they also have difficulties calculating the distance of an object therefore they keep bumping into objects.
In addition, the other symptoms of strabismus are sensitivity to light, blurred vision, and double vision.
