What is Strabismus?

Strabismus, also known as crossed eyes, is a condition in which the eyes do not align properly. In this condition, the eyes are not able to look at the same object at the same time, and one eye may turn in, out, up, or down while the other eye is pointed straight ahead. Strabismus can occur in one or both eyes, and it can be constant or intermittent.

Strabismus can occur at any age, but it is most common in infants and young children. It is estimated that about 4% of children have some degree of strabismus. If left untreated, strabismus can lead to amblyopia, commonly known as “lazy eye,” in which the brain suppresses the image from the misaligned eye, leading to reduced vision in that eye.

There are different types of strabismus, including esotropia, exotropia, hypertropia, and hypotropia. Esotropia occurs when one eye turns inward, toward the nose, while exotropia occurs when one eye turns outward, away from the nose. Hypertropia occurs when one eye is higher than the other, while hypotropia occurs when one eye is lower than the other.

Strabismus can be caused by various factors, including muscle weakness or imbalance, nerve damage, eye injury or disease, and genetic factors. In some cases, the cause of strabismus is unknown.

The symptoms of strabismus can vary depending on the severity and type of the condition. Common symptoms include double vision, eye strain or discomfort, headaches, and difficulty with depth perception. In children, the symptoms may include squinting, closing one eye, or tilting the head to one side.

The treatment for strabismus depends on the severity and type of the condition, as well as the age of the patient. In some cases, glasses or contact lenses may be prescribed to correct any refractive errors. Patching of the “good” eye may also be recommended to strengthen the muscles of the “lazy” eye and improve vision.

In cases where strabismus is caused by muscle weakness or imbalance, eye muscle exercises may be prescribed to strengthen the affected muscles. If these methods are not effective, surgery may be necessary to reposition the eye muscles and realign the eyes.

Strabismus can have a significant impact on a person’s quality of life, particularly in children. Children with strabismus may experience teasing or bullying from their peers, and they may have difficulty with academic or social activities. It is important for parents and caregivers to seek prompt medical attention for any suspected cases of strabismus to prevent long-term complications.

In summary, strabismus is a condition in which the eyes do not align properly, leading to double vision, eye strain, and reduced vision in one eye. It can be caused by various factors and can occur at any age, but it is most common in infants and young children. Treatment options include glasses, eye exercises, and surgery, depending on the severity and type of the condition. Early detection and treatment are important to prevent long-term complications and improve quality of life.
