Amblyopia or “Lazy Eye”

Amblyopia (also called lazy eye) is a type of poor vision that happens in just 1 eye. It develops when there’s a breakdown in how the brain and the eye work together, and the brain can’t recognize the sight from 1 eye. Over time, the brain relies more and more on the other, stronger eye — while vision in the weaker eye gets worse.

It s called ” apathetic eye” on the grounds that the more grounded eye works better. Be that as it may, individuals with amblyopia are not lethargic, and they have zero control over the manner in which their eyes work.

Amblyopia starts in childhood, and it’s the most common cause of vision loss in kids. Up to 3 out of 100 children have it. The good news is that early treatment works well and usually prevents long-term vision problems.

Symptoms of amblyopia can be hard to notice. Kids with amblyopia may have poor depth perception — they have trouble telling how near or far something is. Parents may also notice signs that their child is struggling to see clearly, like:

• Squinting
• Shutting 1 eye
• Tilting their head

In many cases, parents don’t know their child has amblyopia until a doctor diagnoses it during an eye exam. That’s why it’s important for all kids to get a vision screening at least once between ages 3 and 5.

Some kids are born with amblyopia and others develop it later in childhood. The chances of having amblyopia are higher in kids who:

• Were born early (premature)
• Were smaller than average at birth
• Have a family history of amblyopia, childhood cataracts, or other eye conditions
• Have developmental disabilities

In many cases, doctors don’t know the cause of amblyopia. But sometimes, a different vision problem can lead to amblyopia.

Normally, the brain uses nerve signals from both eyes to see. But if an eye condition makes vision in 1 eye worse, the brain may try to work around it. It starts to “turn off” signals from the weaker eye and rely only on the stronger eye.

Some eye conditions that can lead to amblyopia are:

• Refractive errors. These include common vision problems like nearsightedness (having trouble seeing far away), farsightedness (having trouble seeing things up close), and astigmatism (which can cause blurry vision). Normally, these problems are easy to fix with glasses or contacts. But if they’re not treated, the brain may start to rely more on the eye with stronger vision.

• Strabismus. Usually, the eyes move together as a pair. But in kids with strabismus, the eyes don’t line up. One eye might drift in, out, up, or down.
• Cataract. This causes cloudiness in the lens of the eye, making things look blurry. While most cataracts happen in older people, babies and children can also develop cataracts.

As part of a normal vision screening, your child’s doctor will look for signs of amblyopia. All kids ages 3 to 5 need to have their vision checked at least once.

If there’s a vision problem causing amblyopia, the doctor may treat that first. For example, doctors may recommend glasses or contacts (for kids who are nearsighted or farsighted) or surgery (for kids with cataract).

The next step is to re-train the brain and force it to use the weaker eye. The more the brain uses it, the stronger it gets. Treatments include:
