Will I Lose Vision if My Lazy Eye is Left Untreated?

Most people have heard of the term, “lazy eye”. However, it surprises most people to learn that the condition which it describes is not characterized by a lazy eye. Instead the affected eye has a weaker connection to the brain than it should, and subsequently the patient experiences poorer vision in this eye.

Also known as amblyopia, lazy eye is a condition that is especially common in children, with estimated suggesting that around 1 in 50 children experience this type of visual problem. In most cases, a lazy eye is detected and then treated during adolescence. However, there are a number of adult patients who have not had their lazy eye detected and are concerned about the future of their eyesight.

What causes a lazy eye?

To understand what causes a lazy eye, you first need to understand a little about how the eyes work. When we look at something, light passes through the lens located at the front of the eye to reach the retina – a light-sensitive layer of tissue at the back of the eye. The retina then translates the image into nerve signals and sends them to our brain, where the signals from each eye are combined into one 3D image.

The process relies on the connections between our eyes and brain being strong and working correctly – and these strengthen in our first eight years of life. If something interrupts the brain from building strong pathways for information about vision, it can cause the brain to suppress the images from the most affected eye, creating a lazy eye.

It is not always known exactly what causes a lazy eye to develop, but some possible causes include:

While the vast majority of cases of lazy eye occur during childhood, there are a small number of people who develop the condition as an adult. If this happens, it is usually due to muscle or nerve weakness, though in some instances a cause is never firmly established.

Diagnosing a lazy eye

Diagnosis of a lazy eye typically happens during childhood. It is not always immediately obvious that a child has the condition, because their young age makes it difficult for a youngster to tell us exactly what is wrong. However, sometimes you may be able to look at a child and realize that their eyes are not working well together.

Other symptoms include blurred vision, double vision and poor depth perception. Most children will have an eye examination around 3 to 5 years of age, and the eye doctor performing the test should be able to diagnose a lazy eye from this.

Complications of an untreated lazy eye

Whether your lazy eye was left undiagnosed during childhood or you have developed the condition as an adult, the complications of an untreated lazy eye remain the same and include:

Treatment options for lazy eye

There are a number of treatment options that we may suggest for a lazy eye, some of which are also used in children with amblyopia. Typical treatment programs focus on strengthening the weaker eye and encouraging them to work better together. This may involve:
