10 common question about Amblyopia treatment

1Can amblyopia be corrected?
Later, when the alignment is corrected by surgery or the focus corrected with lenses, the visual loss remains. The treatment for the last 200 hundred years has involved patching of the fellow sighted eye, under the rationale of forcing the “lazy” eye to work. ... There is no treatment offered to adults with amblyopia.
2Can amblyopia be treated?
The inhibition process (suppression) can result in a permanent decrease in the vision in that eye that can not be corrected with glasses, lenses, or lasik surgery. Early treatment of amblyopia or lazy eye is usually simple, employing eyeglasses, drops, Vision Therapy, and/or eye patching.
3What is the best treatment for amblyopia?
The Amblyopia Treatment Studies have also demonstrated that weekend use of atropine provided an improvement in visual acuity similar to that of daily use of atropine when treating moderate amblyopia in children aged 3-7 years. Atropine drops or ointment is instilled in the nonamblyopic eye
4Can amblyopia lead to blindness?
Complications. Blindness: If untreated, the patient may eventually lose vision in the affected eye. This vision loss is usually permanent. According to the National Eye Institute, lazy eye is the most common cause of single-eye vision impairment in young and middle-aged adults in the U.S.
5Does amblyopia get worse with age?
Does amblyopia get worse? Vision in the amblyopic eye may continue to decrease if left untreated. The brain simply pays less and less attention to the images sent by the amblyopic eye. Eventually, the condition stabilizes, and the eye is virtually unused.
6Is Amblyopia a disability?
Amblyopia, more commonly referred to as, 'lazy eye,' is an eye condition noted by reduced vision that is not correctable by either glasses or contact lenses. Amblyopia is not caused by any form of eye disease.
7Can a person with amblyopia drive?
Moreover, because the brain doesn't develop the ability to see clearly in one or both eyes, the eyesight of a person with amblyopia cannot be improved with glasses alone. ... A person may have amblyopia with or without an eye turn, a fact which is explained on our amblyopia webpage.
8Can Lasik fix amblyopia?
Typically, LASIK cannot help correct a lazy eye. But there might be an exception... ... It's important to understand the risks of LASIK if you already have amblyopia, however. Many doctors will not perform refractive surgery on the "strong" eye if the best-corrected vision in the amblyopic eye is 20/40 or less.
9Can lazy eyes go away?
Amblyopia will not go away on its own, and untreated lazy eye can lead to permanent visual problems. If later in life your child's stronger eye develops disease or is injured, he or she will depend on the poor vision of the amblyopic eye, so it is best to treat amblyopia early on.
10How is Strabismic amblyopia treated?
Anisometropic and strabismic amblyopia are first treated with spectacle correction, but may require additional, more complex treatment such as penalization therapy if vision does not improve with spectacle correction alone.

How long does it take to correct amblyopia?

Amblyopia, also called lazy eye, is a disorder of sight due to the eye and brain not working well together. It results in decreased vision in an eye that otherwise typically appears normal. It is the most common cause of decreased vision in a single eye among children and younger adults.

The cause of Amblyopia can be any condition that interferes with focusing during early childhood. This can occur from poor alignment of the eyes, an eye being irregularly shaped such that focusing is difficult, one eye being more nearsighted or farsighted than the other, or clouding of the lens of an eye. After the underlying cause is fixed, vision is not restored right away, as the mechanism also involves the brain. Amblyopia can be difficult to detect, so vision testing is recommended for all children around the ages of four to five.

Low price is one of the most important features of Amblyopia in Iran. This is because the cost is less than 100 to 300 percent of the price of Amblyopia in Europe, Turkey, Qatar and the United States, while maintaining the same efficiency. Most surgeons in Iran have high experience in eye surgery.

Most Iranian surgeons graduate from reputable American and European universities and have enough experience to do so.

Causes of Amblyopia

Amblyopia is generally the result of poor visual development during the early years of an individual’s life. It usually occurs before the age of 8. Infants born prematurely or with low birth weight show a greater risk of developing this condition. Brain does not fully acknowledge the images seen by the amblyopic eye. This can be due to a reduction in the amount of light entering the eye, a lack of focus in the eye or confusion between the eyes – where the two images are not the same such as a squint (a condition in which the eyes don’t look in the same direction).

Our eyes function like a camera. An image enters through the lens of each eye and is focused onto the retina which is a light sensitive layer of tissue. The retina translates the image into nerve signals that are sent to the brain. The brain then combines the signals from each eye into a three-dimensional image. The end result of all forms of amblyopia is reduced vision in the affected eye. If left untreated, vision loss occurs due to the improper stimulation of nerve pathways between the brain and the eye.

Symptoms of Amblyopia (Lazy Eye)

Amblyopia (lazy eye) does not usually cause symptoms. Younger children are often unaware that there is anything wrong with their vision and, even if they are, they usually fail to describe their condition unlike the older children who may voice their concerns regarding the inability to see clearly through one eye. In some cases one eye may look different from the other. However, this is usually a sign of another condition that could lead to a lazy eye, such as Strabismus (squint). Strabismus is condition in which the eyes don’t look in the same direction.

Types of Amblyopia:

There are usually three different types of Amblyopia seen among people:

  • Strabismic Amblyopia:

Strabismic amblyopia develops when the eyes are not straight, wherein the eye may turn in, out, up or down. In such a condition, the brain begins to ignore, or “turns off” the eye that is not straight resulting in reduced vision in that eye.

  • Deprivation Amblyopia:

Deprivation amblyopia develops when cataracts or similar conditions “deprive” young children’s eyes of visual experience. If not treated very early, these children never learn to see well and can have very poor vision. Sometimes this kind of amblyopia can affect both eyes.

  • Refractive Amblyopia:

Refractive amblyopia is observed in cases where there is a large or unequal amount of refractive error between a child’s eyes in which the brain learns how to see well from the eye that has less need for glasses and does not learn to see well from the eye that has a greater need for glasses. The vision problem may not be easily identifiable as the child does not complain of blurred vision so long as the good eye compensates for the lack of vision in the amblyopic eye. Also, the eye affected with Amblyopia may not look much different from the normal eye. Hence, because the child’s eyes look normal, parents and physician may not suspect that there could be a problem. For these reasons, this kind of amblyopia in children may not be detected until the child has a vision test. Refractive Amblyopia can affect one or both eyes and can be best helped if the problem is detected early.

Amblyopia Treatment

Amblyopia treatment in Iran at Sanjeevan is designed in such a way that they help the entire visual apparatus (the lens, ciliary muscles, retina and the optic nerve) to relax and re-gain enough strength to recover from Amblyopia. Our treatment helps to improve visual acuity with improvement in the three dimensional vision and also depth perception. It also focuses on conditioning the optic pathway of the amblyopic eye.
If lazy eye treatment is not begun as early as possible, several problems can develop that can seriously affect vision from childhood into adulthood. Some of these complications include the development of serious and permanent visual defect; loss of depth perception (seeing in three dimensions) as 3D vision requires a good vision in both eyes; possibility of a lifetime of poor vision if the stronger eye becomes diseased or injured.
Since the main causes of Amblyopia are Strabismic – by strabismus (misaligned eyes), refractive – by anisomertropia (high degrees of near sightedness, far sightedness or astigmatism in one or both eyes) and deprivational – by deprivation of vision early in life due to disorders that obstruct the vision such as congenital cataract; we treat the symptoms of each of these causes which mainly arises from optical defect. Hence, we treat the optical defect in the eye.

Is there a way to fix amblyopia?

The amblyopia is treatable and typically responds well to strategies such as eye patching and wearing corrective lenses. The best results for lazy eye are typically seen when the condition is treated early, in children who are 7 years old or younger.

  • If the cause of amblyopia is strabismus, additional treatments may include:
    • Eye patches or eye occlusion. A patch is placed over the “good” eye, forcing the muscles in the lazy eye to develop greater strength. Since the brain still receives information from that eye, especially in younger children, it will not ignore the signals and will begin to interpret them. Treatment length will vary depending on how serious the eye’s turn was, how long it had been that way, and how old the child is. Eye patches should be comfortable and remain in place with a child’s regular level of physical activity. The child should not be able to see around the edges, including seeing light filtered through. There are decorated patches available for children to encourage them to wear the patch and to help them have fun during treatment. It is important to encourage your child to leave the patch in place. If your child already has eye glasses, there are patches that attach to the lens of one side of the glass, but this may be a second stage in the treatment process after the non-dominant eye has regained some strength. They are not good for children who are new to treatment.
    • Atropine eye drops. These may be applied to blur vision in the “good” eye. Like the eye patch, this forces the non-dominant eye to become stronger, and signals between that eye and the brain will become stronger. Drops are usually less conspicuous or awkward for the child.
    • Vision exercises.Games and exercises designed to improve vision can strengthen the muscles of the affected eye. Games and activities include coloring in special workbooks, dot-to-dot drawing, word games, or using building blocks, depending on how old the child is. Home-based exercises may be recommended after the weaker eye has regained some strength. These may be done in combination with other treatments.
  • Surgical treatments: Although an optometrist or ophthalmologist will try less invasive treatments first, amblyopia may require surgery to treat strabismus, which is a problem with the muscles that move the eyes. This surgery can be performed in both adults and children. This reduces the eye turn, so the eyes line up better, by either loosening or tightening the muscles as needed. There are two types of strabismus surgery:
    • Recession, when the eye muscle is detached and reattached further from the front of the eye to weaken the muscle
    • Resection, when a portion of the muscle is removed to make the remaining muscle stronger

Can optometrist treat amblyopia?

Ophthalmologists diagnose amblyopia by checking to see if vision differs between the two eyes. To check a baby’s or young child’s vision, the ophthalmologist may cover one of the child’s eyes and watch how well they can follow a moving object. The doctor may also watch how the child reacts when one eye is covered. If one eye has amblyopia and the other is covered, the child may try to look above or below the patch, pull it off or cry.

The ophthalmologist will do a complete medical eye exam, looking for other eye problems that could be affecting vision.

Poor vision in one eye does not always mean a child has amblyopia. In some cases, wearing glasses to correct a refractive error in one eye can improve vision.

What is the best treatment for amblyopia?

Eye drops with a medication called atropine, which blurs the strong eye so your child won’t need to wear a patch. This also forces their brain to use the weak eye. A Bangerter filter worn over the eyeglass lens of the stronger eye to blur their vision so they have to use the weak eye.

How long does it take to correct amblyopia?

For most children with lazy eye, proper treatment improves vision within weeks to months. Treatment might last from six months to two years.

It’s important for your child to be monitored for recurrence of lazy eye  which can happen in up to 25 percent of children with the condition. If lazy eye recurs, treatment will need to start again.
