All about strabismus

Strabismus, commonly known as "crossed eyes" or "wall-eye," is a condition where the eyes do not align properly. Instead of working together to focus on the same point, one eye may turn in, out, up, or down while the other remains straight. This misalignment can be constant or intermittent and affects both children and adults.

Strabismus occurs when the muscles that control eye movement are not working together effectively. The exact cause varies: it can be due to nerve problems, muscle dysfunction, or issues in the brain that control eye coordination. In children, it may be congenital (present at birth) or develop in early childhood, often with no clear cause. In adults, it can result from a stroke, head injury, or conditions like diabetes or thyroid eye disease.

If left untreated, strabismus can lead to amblyopia (lazy eye), where the brain starts ignoring signals from the misaligned eye, leading to vision loss. It can also affect depth perception, self-esteem, and social interaction.

Fortunately, strabismus is treatable. Options depend on age, severity, and underlying causes. Treatments include:

• Eyeglasses or contact lenses: Especially if refractive errors contribute to the condition.
• Prism lenses: Special lenses that help align vision.
• Vision therapy: Eye exercises supervised by an optometrist to improve coordination.
• Botox injections: Temporarily weaken overactive eye muscles.
• Surgery: Adjusts the position or strength of eye muscles to improve alignment.

Early detection is key—especially in children. If you notice signs like misaligned eyes, squinting, or tilting the head, consult an eye care professional. With timely treatment, many people with strabismus can achieve significantly improved eye alignment and function.
