Amblyopia in children
Release time : 04/23/2025 09:30:01
Amblyopia, a condition often unfamiliar to many, is a vision disorder characterized by an inability to correct vision with glasses or contact lenses. Unlike myopia, which is characterized by a visible eye structure abnormality, amblyopia does not involve any physical defects in the eye. It occurs when the eyesight cannot be improved with single-vision corrections to 1.0, and can affect either one or both eyes.
For amblyopia, the best treatment strategy is to detect it early and treat it promptly. The cure rate for adults after diagnosis is virtually nil.
Today, Mawang Dictionary will focus on this aspect of knowledge to provide everyone with a Kop. We hope that through this, everyone can better understand the disease of Myopia.
Amblyopia, a condition that many may be familiar with as nearsightedness, is a serious eye disease that severely impacts children's visual function. Next, let us delve into the scientific knowledge about amblyopia, a topic that may not be widely known.
Amblyopia, where there is no organic lesion in the eye, but the visual acuity of one or both eyes cannot reach 1.0 with corrective lenses, is commonly caused by astigmatism, myopia, or hyperopia. If children have a nearsighted vision that is not effectively managed, it can easily progress to high myopia, leading to a series of pathological changes, and become untreatable in middle and old age.
According to statistics, more than 30% of elderly blindness is caused by post-myopic scleral elongation and comorbid complications such as glaucoma and cataracts.
Amblyopia in children, if not treated in time, can also progress to low vision or blindness.
Corrective lenses are the foundation of treatment for visual impairments. They can correct these refractive errors and enable objects to appear clear, just like adjusting the focal length of a camera.
Without glasses, many cases of amblyopia cannot be effectively treated.
Opt for an optometrist-recommended eye care store that specializes in fitting glasses.
It can ensure that the lens is of good quality, the optical center is good, and the frame does not come loose or vibrate.
Ma Family Encyclopedia reminds everyone that the key to treating amblyopia lies in early detection. Therefore, parents should establish an awareness of regular eye examinations for their children. If a child experiences discomfort with their eyes, it is imperative to seek an ophthalmologist's consultation immediately, so that the condition can be diagnosed and promptly initiated with effective treatment plans.
Amblyopia, a severe eye condition of the child, warrants high attention. There are many causes of amblyopia, with each patient having unique etiologies. Today, we'll discuss the causes of amblyopia in detail.
1. Genetic factors play a role in determining the risk of amblyopia if one or both parents are affected with it.
Under the same principle, if parents have a high degree of myopia or hyperopia, their children may also inherit these conditions, which can lead to congenital myopia or hyperopia in children, all of which can easily result in strabismus.
2. Factors associated with strabismus include children who have had or are currently experiencing strabismus, which is commonly seen in internal strabismus.
When one eye becomes deviated, the visual projection direction changes, and the image formed on the retina of the other eye diverges, resulting in a distorted image that cannot form a complete and clear image when it enters the brain, leading to diplopia.
In order to overcome diplopia and visual disorders, the brain's visual cortex will inhibit the visual impulses from the amblyopic eye actively.
Amblyopia is a condition where the eye with a strabismus cannot function properly due to long-term suppression, affecting visual development and resulting in weak vision.
3. Strabismic amblyopia is caused by the inequality of refractive power, resulting in an unequal size and clarity of objects formed on the retinas of both eyes. The visual cortex of the brain cannot fuse these into a single, clear image; instead, it suppresses the image from the more myopic eye. Over time, this eye develops amblyopia.
4. Factors in the Development of Aphakia-induced Strabismus: After birth, congenital cataracts and corneal opacities can cause light to fail to enter the eye, stimulating the development of the macula in the retina, resulting in an early developmental obstacle to visual acuity.
The impact of childhood amblyopia is significant in real life. It not only affects our vision, making things appear blurry, but also affects children's academic performance, daily life, and future career choices.
Today, Mawang Knowledge Encyclopedia will elaborate on the dangers of amblyopia to better understand it for everyone.
【Affecting Normal Development of Eyes】Amblyopia is a relatively common condition in children. Some children develop it due to nutritional deficiencies, refractive errors, etc.
Amblyopia may lead to and exacerbate myopia, affecting the normal development of the eye. Amblyopia may cause and aggravate myopia, affecting the normal development of the eyes.
【Lack of Spatial Vision】Amblyopia can have significant impacts on individuals, particularly children. If a child suffers from amblyopia, it is crucial for parents to seek timely treatment.
Amblyopia can lead to reduced binocular vision and lack of stereopsis.
"Unable to determine orientation" Strabismus is more detrimental than Myopia.
Simple myopia, blurred when looking at distant objects, clear when looking at near objects.
Children with amblyopia exhibit blurry vision at both distances and near objects, as well as a lack of clear perception of depth and orientation.
"Multi-functional impairments": Blindness can lead to multi-functional impairments in visual function, such as reduced accommodation ability, poor scanning ability, tracking ability, spatial discrimination ability, contrast sensitivity, and hand-eye coordination, among other important visual functions.
Treatment for Myopia in Children: Myopia is a serious eye disease that can severely impair visual development in children. Generally, myopia is considered a common vision problem and not given much attention, leading to missed opportunities for optimal treatment.
So what is amblyopia and how should it be treated? Next, let's delve into the treatment methods for amblyopia.
Ocular refraction is the presence of an astigmatism that causes blurred vision or suppression in the healthy eye.
Thus, through optical lenses, contact lenses, or refractive surgery, the retina of the weak eye is imaged clearly to lay a foundation for visual development.
For all patients with amblyopia who are diagnosed with refractive error after examination, they need to keep wearing glasses frequently and cannot be removed and worn to ensure good eye adaptation to the lens and stable optical correction effect.
Occlusion and optical correction are called the cornerstones of amblyopia treatment.
Especially for amblyopia patients with inconsistent degrees of amblyopia in both eyes, the scientific nature and execution of the covering plan play an absolute role in the treatment of amblyopia.
The most common method of covering is to cover healthy eyes (one eye with better vision).
After the healthy eyes are covered and visually deprived, the poor eyes can gain visual perception and visual transmission, so that the poor eyes can gain exercise and excitement.
[Enhanced vision and amblyopia training] Optical correction creates clear retinal imaging and masking eliminates eye inhibition, while enhanced vision and amblyopia training uses specific visual input signals to create a stronger exciting vision than daily visual input signals.
Make amblyopic eyes get easier to perceive and more appropriate spatial frequency stimulation in a short period of time.
[Bilateral Visual Training] For patients with bilateral visual impairment and strabismus,
After completing the vision enhancement and amblyopia training, the corrected vision of both eyes will reach 1.0 or higher, which is not the end point of amblyopia treatment.
Patients with amblyopia have corrected visual acuity higher than 0.6 in both eyes and have the ability to perceive simultaneously.
You can do binocular vision training.
Binocular vision training can be roughly divided into three stages: simultaneous vision training, fusion training and stereo vision training.
These three stages can be subdivided into targeted training to overcome visual dysfunction.
Patients with amblyopia with constant strabismus should have surgery to correct strabismus after their corrected vision approaches normal, and binocular vision training should be performed after surgery.
Postural treatment for amblyopia should not end after the visual acuity reaches normal values (more than 0.1 in logarithmic scale or more than 5 in logarithmic scale) and binocular vision is intact.
Only when the above standards are consistently met can we consider the treatment of amblyopia as successful.
The standards for the complete cure of amblyopia (1987) formulated by the Chinese Medical Association are: corrected visual acuity greater than or equal to 0.9, stereopsis less than or equal to 60, and stable for more than three years.
Many people know about myopia, but they don't understand strabismus well. Some parents even mistake it for myopia and fail to pay attention to it, which leads to the child missing the best opportunity to treat strabismus.
So, what exactly is the difference between amblyopia and myopia? Today, let's delve into these aspects of knowledge with Mawang Dictionary.
【Essential Differences】Myopia is an eye disease caused by excessive tension of the ciliary muscle, which causes the eye to grow longer and blur vision at a distance. However, once corrective lenses are worn, the vision can return to normal.
Amblyopia is an eye disease with delayed and disorder of visual function, often accompanied by strabismus and high refractive error. Vision cannot be corrected to normal even with glasses.
[Different harms] Myopia is only a decrease in vision and is not accompanied by other visual function damage. Vision can be corrected and is not limited by age.
Patients with amblyopia not only have reduced vision and cannot be corrected, they are unlikely to have binocular single vision, have no stereo vision, and will not be competent for driving, surveying and mapping and fine work in the future.
According to the survey, 20% of people who have car accidents lack stereo vision.
The quality of vision and the presence or absence of stereoscopic vision will directly affect the child's physical and mental health and employment future.
From the above introduction, you can understand that the impact of amblyopia on children cannot be ignored. If correction and treatment are not carried out in time, the visual function will be very harmful. Not only will it be difficult to see clearly, but it will also cause a lack of stereoscopic vision.
The best age for treating amblyopia is preschool age. It is difficult to cure after 12 years old. If you enter adulthood, there is basically no hope of treating amblyopia.
