Are you struggling with eye strain? And finding out that one of your eye has a low vision, You may be experiencing symptoms of Amblyopia that affects millions worldwide. Also known as lazy eye, Amblyopia is a treatable disease that occurs when the brain favours better eye over the eye with low vision, leading to impaired vision and depth perception. If left untreated, amblyopia can cause permanent decrease vision and increase the risk of other serious eye conditions.
At EDO Eye Hospital, we understand the importance of early detection and treatment. That’s why we offer free checkups and treatment to deserving individuals. Let’s dive into the causes, symptoms, and treatment options of Amblyopia, and take the first step towards clearer vision and a healthier future.
An introduction to Amblyopia?
Amblyopia, commonly referred to as lazy eye, is a neurodevelopmental or disorder that occurs when the brain fails to properly process visual information from one or both eyes. This may lead to reduced vision, blurred vision, or double vision. It is a neurological issue that affects the way the brain processes visual data.
It can occur in three ways:
- Monocular Amblyopia: Affects one eye. It often occurs due to a significant difference in refractive error or vision obstruction.
- Binocular Amblyopia: Affects both eyes. Binocular amblyopia occurs often due to a high refractive error or other eye conditions.
Types of Amblyopia
Amblyopia can be classified into different types based on its severity and impact on the eyes. Understanding its type and severity is crucial for developing an effective treatment plan and preserving eyesight.
Strabismic Amblyopia:
Strabismic Amblyopia: It is caused by misaligned eyes where the brain favors the straight eye, causing the other eye to lose vision over time. Strabismus Amblyopia can be further divided into
- Esotropia (crossed eyes)
- Exotropia (wall-eyed)
- Hypertropia (vertical deviation)
Refractive Amblyopia
Refractive amblyopia results from unequal refractive errors between the two eyes. It can be nearsightedness, farsightedness, or astigmatism. It results in the brain favoring the eye which has clearer vision.
Deprivation Amblyopia
Deprivation amblyopia can have many causes such as Cataracts, Ptosis (droopy eyelid), Corneal scarring, and Eye injuries.
Mixed Amblyopia
Mixed Amblyopia is a combination of strabismic and refractive amblyopia. It may occur due to conditions including blepharoptosis, optic nerve coloboma and hypoplasia, retinal disorders, congenital cataracts, persistent fetal vasculature, and nystagmus disorders.
Anisometropic Amblyopia
This type of Amblyopia is caused by differences in refractive errors between the two eyes, leading to unequal image size and blurred vision.
Stimulus Deprivation Amblyopia
It is caused by the obstruction of the passage of light stimulus to the eye due to conditions like cataracts, corneal opacities, or eyelid abnormalities.
Functional Amblyopia
Resulting from abnormal binocular vision, functional amblyopia is a condition where the brain has difficulty combining images from both eyes.
Organic Amblyopia
Its cause may be an underlying eye disease or condition, such as macular degeneration, retinal detachment, or optic nerve damage.
Reverse Amblyopia
Reverse amblyopia is a rare condition where the brain favors the weaker eye leading to vision loss in the stronger eye.
Amblyopia Causes:
Amblyopia eye disease is often caused by abnormal visual development during childhood but it can also be caused by various other factors. Understanding the causes of Amblyopia is
essential for its prevention, early detection, and effective treatment. Here are some common causes of Amblyopia eye disease:
- Strabismus (crossed eyes) or misaligned eyes lead to conflicting signals in the brain. This causes amblyopia.
- Refractive errors in nearsightedness, farsightedness, or astigmatism between the two eyes can cause Amblyopia.
- Deprivation of vision caused by cataracts, ptosis (droopy eyelid), or corneal scars can block vision and lead to Amblyopia.
- Genetics or a family history of Amblyopia can play a role in the development of this condition.
- Premature infants are also at a higher risk of developing Amblyopia.
- Amblyopia can also be caused by eye injuries or trauma to the eyes.
Prevention and early detection of amblyopia are effective In preventing the spread of this disease which may otherwise lead to permanent vision loss. In some cases, this disease may be caused by a combination of factors which is why a comprehensive eye evaluation is necessary to help determine the underlying cause and accurate treatment.
Amblyopia Symptoms
Its symptoms may vary depending on the severity and type of condition however common symptoms include
- Blurry vision or unclear vision in one or both eyes
- Double vision (ghosting)
- Eye strain or fatigue
- Squinting or tilting of the head to see things clearly
- Difficulty judging distances or depth perception
- Avoiding tasks that require visual attention
- Redness or tearing of the affected eye
- Difficulty tracking objects or following instructions
- Discomfort in performing visual tasks
In some cases, Amblyopia may not exhibit noticeable symptoms, especially in children. However, as the condition progresses, symptoms can become more pronounced. If left untreated, Amblyopia can lead to permanent vision loss and increased risk of other eye diseases. That is why family treatment is important for improved visual outcomes.
If you or a loved one is suffering from any of these above-mentioned symptoms, consult eye care professionals immediately for a comprehensive evaluation and tailored guidance.
How to Treat Amblyopia
Treatment of Amblyopia requires a comprehensive approach that addresses the underlying causes and promotes healthy vision development. The primary goal of the treatment is to improve vision and prevent permanent vision loss in the affected eye. Treatment options for Amblyopia include:
- Patching therapy: The stronger eye is covered with a patch to force the brain to rely on the weaker eye.
- Vision therapy: It involves customized exercises and activities to improve visual acuity, depth perception, and eye coordination.
- Refractive correction: Glasses or contact lenses to correct refractive errors.
- Surgery: It either aligns the eyes (strabismus surgery) or removes vision-obstructing factors (e.g., cataracts).
- Atropine therapy: Similar to patch therapy, here atropine is used to dilate the stronger eye to blur its vision and encourage the use of the weaker eye.
- Orthoptic therapy: This type of therapy includes eye exercises and training to improve eye movement and coordination.
After a thorough examination and check-up, a certified eye specialist may recommend a combination of these treatments tailored to your present condition. As soon as you notice amblyopia symptoms it is recommended to consult an eye professional, for the best possible course of treatment. However, there are some home-based activities that can support visual development in case of amblyopia, such as:
- Engaging in visually stimulating activities such as puzzles, coloring, reading, and playing games
- Encouraging outdoor play to promote depth perception and eye coordination
Complications and risks of Amblyopia eye disease
If Amblyopia is left untreated, it can cause several risks and complications such as:
- It may lead to permanent vision loss In the affected eye
- It may affect the ability to judge distances and depths leading to the risks of accidents and injuries
- It may increase the risk of developing other eye diseases such as glaucoma, cataracts, or retinal detachment.
- It can lead to crossed eyes (Strabismus) which can cause strain, double vision, and social stigma.
- Impact and daily life activities, social interactions, and overall quality of life.
- It may also cause binocular vision problems (the ability to use both eyes together).
- It may lead to a higher risk of developing Amblyopia in the other eye.
- Delaying treatment may lead to more complex and riskier surgical procedures
