It is reduced vision in an eye that has not received adequate use during early childhood. It is also known as “Lazy eye”. It is common problem in babies and young children.
It is important to diagnose and treat amblyopia as early as possible because a child’s vision develops in first few years of life.
It is caused by either a misalignment of a child’s eyes, such as crossed eyes or a difference in image quality between the two eyes. It starts when one eye has much better focus than the other. When child's brain gets both a blurry image and a clear one, it starts to ignore the blurry one. If this goes on for months or years in a young child, vision in the blurry eye will get worse.
Kids who are suffering from amblyopia cannot focus their eyes together on an image, so they often see double. Some children are born with a cataract, where the eye’s normally clear lens is cloudy. This can keep vision from developing properly in that eye. The child’s brain will ignore the image that is not aligned.
All children should be tested before they are school-age. The doctor will check to make sure that:
• Nothing blocks the light coming into her eyes.
• Both eyes see equally well.
• Each eye moves like it should.
Force child to start using weak eye. The doctor will look for problems in that eye, like near-sightedness, farsightedness, or astigmatism and correct them first. If a cataract is blocking light from an eye, the doctor may recommend surgery to remove it. Then he will give a patch to wear over a strong eye. It can take several weeks to several months for vision to get stronger in the weaker eye.
