Amblyopia is a condition that causes decreased vision in one of or both of the eyes due to abnormal development of the vision in the infancy or childhood. IN amblyopia. There may not be a distinct issue in the eye. Vision loss occurs due to nerve pathways between the brain, and the eye is not effectively stimulated. The brain can learn to see only blurry images with the amblyopic eye even when glasses are used. As a result
What Causes Amblyopia?
Amblyopia normally starts when one eye has a much better focus than the other eye. A person may have an eye that is very farsighted or have a lot of astigmatisms; others may not. When a child’s brain is faced with both a blurry image and a clear one, it begins to ignore the blurry image. If this happens for a series of months or years, the young child’s vision will begin to deteriorate in the eye that has blurry images.
Another cause of amblyopia is strabismus, which is an ocular misalignment, indicating that one eye turns inward or outward in the direction that it is looking. This prevents the eyes from focusing together on an image and may cause double vision. To address this misalignment a child’s brain will normally choose to ingrain the image from the deviated eye, making the vision in that eye to deteriorate. It is this misalignment of the eyes that leads some people to call amblyopia ’lazy eye.”
What types of amblyopia are there?
There are various types and causes of amblyopia: There is refractive amblyopia, deprivation amblyopia, and strabismus amblyopia. The result of all forms of amblyopia is declined vision in the affected eyes.
What is refractive amblyopia?
Refractive amblyopia creates a significant refractive error (glasses strength) between a child’s eyes. The brain learns how to see better from the eye that has less need for glasses and does NOT learn to see well from the eye that less need from the eye that has a larger need for glasses. The vision difficulty may be undetectable because the child does not complain of blurry vision. The child sees well with the better-seeing eye.
Strabismic amblyopia occurs when the eyes are not straight. One eye may turn in, out up or down. When this happens, the brain to ignore, or turns off the eye that is not straight and the vision subsequently drops in that eye.
Deprivation amblyopia occurs when cataracts or related conditions deprive adolescent children’s eyes of visual sense. If not treated very early in the process, these children never learn to see very well and can have very poor vision. Sometimes Deprivation amblyopia kind of amblyopia can affect both eyes.How is Amblyopia Diagnosed?
All children should be screened before they old enough to go to school. Your child’s doctor or the vision program at school will check three aspects of your child’s eye health.
- Your frequently’s eyes let light all the way through
- The eyes move normally
- Both eyes see equally well.
If there is a problem in any area of the eye, the doctor or school nurse may suggest a visit to an eye specialist. If you feel that anything could be abnormal with your child’s vision, you should call your doctor even if your child has already been screened at school.
Some eye doctors recommend an exam at 6 months , and three years, them very two years in the school years. Ask your doctor or your right doctors what options are right for your child.
A family history of amblyopia is a risk factor for the condition. Parents can not tell just be looking at their child if they have amblyopia. Early diagnose and treatment is key to the best visual outcome.
The most frequent treatment for amblyopia is to push the brain to start using the affected eye. This is done by first correcting the underlying issue in that eye and then putting a patch over the “good’ or working eye. However, it is imperative that your child wears the patch routinely because this will eventually improve vision. It can take weeks or months for the eye patch to improve vision. You should follow the doctor’s instructions exactly and follow the schedule to bring your child to the eye doctor to be observed closely during treatment.
As the child keeps using the eye with amblyopia, his or her vision will continue to get better and improve its vision. After the doctor determine that vision is back to normal, your child ill does not have to wear a patch on a full-time basis. Some children may lose some vision again and need to experience another round of wearing a patch. In cases of mild amblyopia. The doctor might advise using an eye drop called atropine in the “healthy or functional” eye instead of a patch. Atropine dilates the pupil and clouds the vision in the “healthy or functional” eye, forcing the “weaker” eye to do the most of the work, while the child is playing ,eating, drawing ,reading , or writing.
Most children with amblyopia will also require glasses to help focus. If there is anything such as a cataract blocking light from getting into the eye, the doctor may recommend surgery to remove the blockages. If strabismus is preventing the eyes from moving together perfectly, your doctor might suggest surgery on the muscles of the eye. Your doctor will review with you what treatment will be the most effective treatment.
Outlook of for children
If the underlying problems are treated and the amblyopia is detected early in the process and treated, most children will gain vision. Amblyopia becomes much more challenging to treat after about 7-9 years of age., so stick to the recommendation about early childhood exams.
Make sure you follow your doctor’s advice about treatment even when It is difficult. Many children will not want to wear an eye patch every day. With the use of atropine
as an alternative method of treatment success in now possible in a large segment of children with amblyopia.
Will glasses help a child with amblyopia vision improve?
Glasses can enhance visual acuity to some level, but normally not entirely. With amblyopia, the brain is accustom to seeing a blurry image and needs to learn how to see normally with that eye. The eye may relearn how to see out of that eye.
