Amblyopia (Lazy Eye) Symptoms

What is amblyopia?

Amblyopia is an eye disorder that is characterized by poor vision in an eye that is otherwise physically normal. More commonly known as "lazy eye", this condition may arise from one eye being out of proportion to certain associated structural abnormalities of the human visual system.

Amblyopia usually is a condition that affects humans during early childhood. It can be caused by either a lack or poor transmission of visual images from the eye to the brain for sustained periods. This condition usually affects only one eye although it might also be possible that both eyes may be affected if they are both deprived of getting a good and clear visual image.

Amblyopia is usually an eye disorder that can be traced to developmental problems in the brain rather than the physical problem concerning the eye itself although there are also certain instances that lazy eye may be caused by organic problems in the eyes.

It can be caused when the part of the brain that corresponds to the visual system is not being stimulated properly or develops abnormally. They may initially develop from the period between birth to two years after in humans. The condition may further develop in kids before the age of six.

Mild amblyopia can remain undetected in some people. But usually, the disorder can be characterized by an eye that wanders inward or outward. It can sometimes look like the eyes are not working in sync with each other, making them poorly aligned when it comes to proper positioning. In this case, poor alignment can result in poor depth perception. Anything that can blur vision or causes the eye to cross especially in young children can be a probable cause of lazy eye.

What causes amblyopia?

One of the most common causes of the disorder is strabismus, an imbalance in the eye muscles responsible for eye positioning that can cause the eyes to cross or turn outward of each other. Amblyopia can also be caused an anatomic or structural abnormality in the visual system such as abnormalities in the central retina or a cloudy area in the lens of the eye. Abnormal eye shape and size may also contribute to the development of lazy eye in children.

Symptoms of amblyopia

Symptoms of amblyopia include poor depth perception. People suffering form lazy eye may also experience poor spatial acuity as well as low sensitivity to contrast. People with amblyopia may also suffer from a reduced sensitivity to motion. Some people with lazy eye may also experience difficulties seeing three dimensional images.

These symptoms are usually only experienced by the amblyopic eye with the dominant eye usually operating normally. Amblyopia may run in families and may likely develop among children born prematurely or experience developmental delays. The re are different treatments for amblyopia depending on the underlying cause which doctors first try to look into.
