What causes Strabismus?

The cause of strabismus can stem from a number of factors, including abnormalities in the eye muscles, nerves controlling these muscles, and vision centers in the brain that regulate binocular vision. It can also result from poor vision in one or both eyes. Additionally, genetics can also play a role, with children of parents with strabismus having a higher likelihood of developing the condition. Strabismus can present at birth, during infancy or childhood, or later in life, and in some cases, it may be an indicator of a more serious eye disease or health issue. Other contributing factors include eye or orbital injury, head trauma, premature birth or low birth weight, uncorrected farsightedness, muscular or neurological abnormalities, cerebral palsy, and Down syndrome.

Amblyopia and Strabismus

Amblyopia, also known as "lazy eye," is the most common cause of strabismus in children. In this condition, one eye does not develop properly, and as a result, it does not function correctly. This can lead to reduced vision in the affected eye and a misalignment with the other eye. It can be caused by a variety of factors, including a difference in the refractive power of the eyes, a misalignment of the eyes, or a blockage of vision in one eye. If detected early, amblyopia can often be successfully treated with patching or other therapies.

Esotropia and Exotropia and Strabismus

Esotropia is a form of strabismus that occurs when one eye turns inward, towards the nose. It can be caused by a variety of factors, including muscle imbalances or farsightedness. The misalignment caused by esotropia can lead to amblyopia, where the brain begins to ignore the misaligned eye.

Exotropia is a form of strabismus where one eye turns outward, away from the nose. Like esotropia, exotropia can be caused by muscle imbalances or nearsightedness. If left untreated, it can lead to amblyopia, where the brain begins to ignore the misaligned eye. Esotropia and exotropia are two of the most common forms of strabismus in adults. They can be caused by a variety of factors, including neurological conditions, eye injuries, or problems with the eye muscles. Treatment options for these conditions may include glasses, eye exercises, and surgery.

Special Needs and Strabismus

Down Syndrome is a genetic disorder that can cause a range of physical and intellectual disabilities. It is one of the conditions that can increase the risk of developing strabismus, with estimates that between 20% and 60% of people with Down Syndrome have strabismus. In individuals with Down syndrome, the risk of developing strabismus may be due to genetic factors, but it can also result from other associated health conditions. Early detection and treatment of strabismus can help improve vision and prevent complications, so it is important to monitor the eye health of individuals with Down syndrome and schedule a functional or developmental eye exam if any symptoms of strabismus are present.

Cerebral Palsy is a group of neurological disorders that affects movement and muscle coordination. In some individuals with cerebral palsy, strabismus can also develop. This is because the disorder can cause abnormalities in the nerves that control eye movement and muscle coordination, leading to a misalignment of the eyes. Children with cerebral palsy have an increased risk of developing strabismus, and in some cases, the condition may worsen as they grow older. Treatment for strabismus in individuals with cerebral palsy may involve eye exercises, glasses, or in severe cases, surgery to correct the misalignment of the eyes. It's important to note that prompt and appropriate treatment can improve the visual function and quality of life for individuals with both cerebral palsy and strabismus.

Nerve that control eye movement and Strabismus

Cranial Nerve Palsies is a condition that can affect one or more of the nerves that control eye movement, leading to strabismus. Cranial nerve palsies can be caused by a variety of factors, including head injuries, strokes, or tumors. Treatment options for this condition may include surgery, eye patches, or glasses.

Duane Syndrome is a rare eye movement disorder that affects about 1 in 10,000 people. This condition occurs when the nerves that control eye movement are not functioning properly. As a result, affected individuals may experience difficulty moving their eyes in certain directions or may have a misalignment of the eyes. The condition is usually diagnosed in early childhood, and treatment options may include eye exercises or surgery.

Fourth Nerve Palsy is a condition that occurs when the fourth cranial nerve, which controls the movement of the superior oblique muscle, is damaged. Fourth nerve palsy can be caused by a range of factors, including head trauma, infections, and vascular disorders. Symptoms may include double vision, head tilt, and a misalignment of the eyes. Treatment options may include eye patches, prism lenses, and surgery to correct the muscle abnormality.

Sixth Nerve Palsy is a condition that occurs when the sixth cranial nerve, which controls the movement of the lateral rectus muscle, is damaged. Sixth nerve palsy can be caused by a range of factors, including head trauma, infections, and vascular disorders. Symptoms may include horizontal double vision, eye strain, and a misalignment of the eyes. Treatment options may include eye patches, prism lenses, and surgery to correct the muscle abnormality.

Eye muscle and eye control and strabismus

Convergence Insufficiency is a condition that occurs when the eyes have difficulty working together to focus on objects that are near. Although the exact connection between convergence insufficiency and strabismus is unknown, between 10-20 percent of those who have strabismus, also experience convergence insufficiency of some degree. 

Brown Syndrome is a rare condition that affects the muscles that control eye movement. It occurs when there is an abnormality in the trochlea, a small cartilaginous loop through which the superior oblique muscle passes. Brown Syndrome can cause limited movement of the affected eye, resulting in strabismus. Symptoms of Brown Syndrome may include a painful or restricted movement of the affected eye, double vision, and a misalignment of the eyes. Treatment options may include eye patches, prism lenses, and surgery to correct the muscle or trochlear abnormality

Autoimmune diseases, thyroid and strabismus

Myasthenia Gravis is an autoimmune disorder that can cause muscle weakness and fatigue, including in the muscles that control eye movement. Myasthenia gravis can cause a range of visual symptoms, including double vision, drooping eyelids, and strabismus.

Graves disease and other thyroid diseases can be a potential cause of strabismus as an autoimmune response can affect the muscles controlling eye movement. The eye muscles become swollen and cause the eyes to become misaligned, leading to double vision and strabismus. Additionally, Graves disease can cause inflammation and fibrosis of the extraocular muscles, leading to strabismus. The connection between strabismus and thyroid diseases highlights the importance of regular check-ups and monitoring of thyroid health to prevent the development of eye disorders.

Common Questions

Strabismus can be caused by a variety of factors, including problems with the eye muscles, nerves, or brain. Some of the most common causes of strabismus are: Abnormalities in the eye muscles or nerves controlling them: This can result in imbalanced eye movement, leading to strabismus. Amblyopia, or "lazy eye": This occurs when one eye is consistently used over the other, causing the eye that is not being used to drift out of alignment. Refractive error: Refractive errors, such as nearsightedness, farsightedness, or astigmatism, can cause a misalignment of the eyes, resulting in strabismus. If not corrected, these refractive errors can lead to amblyopia and strabismus. However, there are many other conditions that can lead to strabismus, including neurological disorders and eye conditions like cataracts. A thorough functional eye exam by our optometrist can help determine the underlying cause of strabismus.
Strabismus is often mislabeled as "lazy eye," but it is important to note that these terms do not refer to the same condition. Lazy eye, or amblyopia, is a separate eye condition that can cause reduced vision in one eye due to a failure of the brain to fully recognize the visual input from that eye. Strabismus, on the other hand, refers to a misalignment of the eyes that can cause visual confusion and other symptoms.
Several neurological conditions can cause strabismus, including cerebral palsy, stroke, multiple sclerosis, and myasthenia gravis. These conditions can affect the nerves or structures in the brain that control eye movement, leading to misalignment of the eyes and strabismus.
Strabismus can be caused by a variety of problems with the brain or nervous system, but the specific part of the brain that is affected can depend on the underlying cause of the strabismus. In some cases, the muscles or nerves that control eye movement may be affected, while in other cases, the parts of the brain responsible for processing visual information may be affected.
Several factors can worsen strabismus, including stress, fatigue, illness, and certain medications. In addition, certain eye conditions, such as cataracts or uncorrected refractive errors, can also exacerbate strabismus by interfering with visual input to one or both eyes.
While stress can exacerbate some symptoms of strabismus, it is not a direct cause of the condition. Strabismus is typically caused by a variety of structural or neurological factors that affect the alignment of the eyes and can interfere with binocular vision.
People with strabismus may experience a variety of visual symptoms, depending on the severity and type of the condition. Common symptoms include double vision, visual confusion, eye strain, and a misalignment of the eyes. Some people with strabismus may also experience reduced visual acuity in one or both eyes, as well as difficulty with depth perception and other visual tasks.
