What is strabismus?
Strabismus, often referred to as "crossed eyes" or "wandering eyes," is a condition where the eyes don’t align properly. This misalignment affects both children and adults and can lead to visual difficulties. Understanding strabismus, its causes, and treatment options is the first step toward finding a solution.
Understanding Strabismus
Strabismus occurs when the eyes don’t work together to focus on a single point. Instead, each eye may look in a different direction, causing a misalignment that makes it hard to see clearly. This misalignment can be constant or intermittent and may affect one or both eyes.
The condition can cause symptoms such as double vision, eye strain, or difficulty focusing. For children, it can lead to amblyopia, or "lazy eye," where the brain begins to ignore the visual input from the misaligned eye.
Types of Strabismus
There are several types of strabismus, classified by the direction the eye turns:
- Esotropia: One or both eyes turn inward (often known as "crossed eyes").
- Exotropia: One or both eyes turn outward (often called "wall-eyed").
- Hypertropia: One eye points upward.
- Hypotropia: One eye points downward.
These types of strabismus can appear in different situations, such as when focusing up close, at a distance, or in dim light.
What Causes Strabismus?
Strabismus results from an imbalance in the eye muscles, which control the movement of each eye. When these muscles don’t work in harmony, the eyes can’t align properly. There are several reasons why this may occur:
1. Genetics
Strabismus can run in families. If a close relative has the condition, there’s a higher chance of it appearing in children.
2. Neurological Issues
Conditions affecting the brain, such as cerebral palsy, Down syndrome, or a stroke, can impact eye alignment by disrupting muscle control.
3. Eye Conditions
Eye problems like cataracts or severe refractive errors (such as nearsightedness or farsightedness) can lead to strabismus if untreated.
4. Muscle and Nerve Issues
Damage to the nerves that control eye muscles, due to injury or illness, can cause strabismus by weakening muscle function.
The Symptoms
Strabismus symptoms vary depending on the type and severity of the condition:
- Double Vision: Many people with strabismus see two images of a single object.
- Eye Strain: Constant misalignment can lead to discomfort and fatigue in the eyes.
- Head Tilting: To try and see clearly, some people tilt their head or squint.
- Reduced Depth Perception: Misalignment can make it difficult to judge distances accurately.
For children, one eye may become dominant, leading the brain to ignore input from the misaligned eye. Early diagnosis is crucial to prevent amblyopia, or "lazy eye."
Diagnosing Strabismus
Diagnosing strabismus requires a comprehensive eye exam, including tests to check eye alignment, movement, and overall health. Your eye specialist may use tools such as:
- Cover Test: The doctor covers one eye at a time to check for movement.
- Ocular Motility Test: This test checks how well the eyes can move and follow an object.
These tests help determine the type of strabismus, its severity, and the best treatment approach.
Treatment Options
Treatment for strabismus aims to align the eyes, improve vision, and restore depth perception. Depending on the cause and severity, treatments may include:
1. Glasses or Contact Lenses
For those with refractive errors, corrective lenses can help focus the eyes properly, reducing misalignment. Special lenses, such as prism glasses, may also be used to help the eyes work together.
2. Surgery
Surgery can adjust the length or positioning of certain eye muscles, helping the eyes to align properly. It’s often recommended if other treatments haven’t achieved the desired results. In many cases, surgery is an effective, long-term solution for strabismus.
The Importance of Early Treatment
Early diagnosis and treatment are critical, especially for children. Untreated strabismus can lead to vision loss in one eye, as the brain begins to ignore the input from the misaligned eye (a condition known as amblyopia). For adults, untreated strabismus can cause persistent double vision and limit depth perception.

Living with Strabismus
Living with strabismus can be challenging, but treatment offers real benefits. Vision therapy, or surgery can significantly improve quality of life, allowing those with strabismus to see more clearly, judge distances accurately, and gain confidence.
For children, treatment can make a big difference in social interactions and learning. Adults also benefit from increased visual comfort and a reduction in double vision or eye strain.
Strabismus can be managed effectively with the right treatment. If you’re noticing symptoms of strabismus in yourself or a loved one, don’t wait.
