Amblyopia Causes Signs and Symptoms Diagnosis and Treatment
A child's vision isn't developing properly can cause amblyopia (lazy eye). It's important to have regular eye exams for infants and children.
The best way to prevent amblyopia is to catch it before it starts. This is easier if tests are done early in a child's life.
Strabismus
Strabismus (pronounced struh-biz-muhs) is a vision problem in which one or both eyes don't line up correctly. This can happen all the time or only during certain situations, such as when looking at a bright light or viewing far away objects.
The resulting misalignment causes the brain to send different images to each eye. This can cause double vision and lead to problems with depth perception, or seeing in 3D. A great read
Diagnosis of strabismus usually involves standard eye tests. These include covering the eye to watch it shift in direction, a light reflex test, and retinal testing.
Treatment for strabismus often includes glasses of the correct power, patching of the stronger eye, and sometimes a once-a-day drop of an eye drug called atropine that blurs near vision in the weaker eye. These treatments aim to strengthen vision in the weaker eye and prevent amblyopia from developing.
If strabismus is discovered early and treated, the eye and brain can form normal connections to each other and vision can improve. However, if left untreated, the brain will eventually ignore visual images from the weaker eye. This can result in amblyopia, which may be reversible or permanent, depending on the child's age and treatment.
Refractive Error
Refractive error can make vision hazy or blurry and can affect both close-up and distant objects. This can also cause headaches and tired eyes.
If you're experiencing refractive errors, be sure to schedule regular eye exams with an ophthalmologist or optometrist. They can diagnose refractive errors, determine the severity and prescribe treatment to get you back to your normal vision.
During routine tests, eye professionals use an eye chart to measure how sharp your vision is in comparison to what a person with normal vision can see. This test is called visual acuity and is used to help diagnose refractive error issues. Check this out
Cataracts
Cataracts are a common eye problem in older people. However, they can also occur in younger people and in babies who are born with a cataract (congenital cataract).
A cataract is a clouding of the clear part of your eye lens. It forms for several different reasons and affects different parts of your lens.
Your eye's lens is made of a nucleus in the center and a cortex that surrounds it. It's covered by a thin membrane, called a lens capsule.
Occasionally, a nuclear sclerotic cataract forms just inside the front of your lens capsule. This type of cataract can develop after an injury or swelling in your eye.
When you have a cataract, your vision is cloudy or blurry and may become more noticeable over time. Light from the sun or a lamp seems brighter, glare from headlights is more noticeable, and colors seem darker than usual.
Muscle Imbalance
Often, the eyes don’t move in sync when it comes to vision. This happens when the muscles in and around the eye don’t work together properly. This may result in strabismus, where the eyes don’t line up correctly.
Strabismus can also be caused by other problems, such as a lazy eye (amblyopia). Amblyopia occurs when the brain ignores pictures from the weaker eye, instead focusing on the normal one.
This can be a problem when the child is learning to see, but can also happen in adults who have a weaker eye or a condition that affects their vision. Amblyopia is usually diagnosed in children between the ages of 3-5 before their visual system has fully developed.
A physical therapist can help determine whether or not a muscular imbalance is present. They can also design an exercise program to restore muscle balance and improve joint stability and mobility. Muscle imbalances can occur for a variety of reasons, including poor posture, repetitive motions and sports.
