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 also known as squint, lazy eye, crossed eye, boss eye, cock eye and wall eye. 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 tell if the person is affected by the condition.
One of the symptoms of strabismus is that the eyes are not able to look in the same direction concurrently. The reason for this is that the extraocular muscles may be weak and therefore are unable to coordinate the movement of the eyes. This brings about to an impaired binocular vision causing the person to have a lessened field of view and problems in depth perception.
One more symptoms of strabismus is that the eyes are not able to move together. The direction of the eyes is dependent on the type of strabismus that the patient has. Estropia also known as crossed eyes is the most typical type wherein one eye turns inward. Another form is exotropia or walleye wherein one eye turns outward towards the temple. There is also the less common forms hypertropia or vertical deviation wherein the eye turns upward towards the eyebrow, or hypotropia wherein the eye turns downward.
As a result of the impaired vision from the lack of binocular vision, the other symptoms of strabismus are tilting of the head to look in an object, closing one eye in the bright daylight, and bumping into things.
People who are affected by strabismus are not able to use both their eyes at the same time and that is why they have to squint or close their eyes. They also are unable to correctly judge the depth of an object visually and so they have to tilt their heads. And they may also have problems estimating the distance of an object hence they keep on bumping into various objects.
Furthermore, the other symptoms of strabismus may also include double vision, blurring of vision, tired eyes, and sensitivity to light.
