Amblyopia, commonly known as lazy eye, is a condition in which vision in one eye does not develop properly during childhood. It occurs when the brain and eye do not work together correctly, causing the brain to rely more on the stronger eye and ignore the weaker one.
Over time, this can lead to reduced or permanent vision loss in the affected eye if not treated early. Amblyopia is the most common cause of vision problems in children.
Amblyopia is classified based on its cause:
1. Strabismic Amblyopia
Occurs due to misalignment of the eyes (crossed or wandering eyes).
2. Refractive Amblyopia
Caused by unequal vision (power difference) between both eyes.
3. Deprivation Amblyopia
Occurs when something blocks light from entering the eye, such as cataract.
Amblyopia symptoms are often difficult to detect, especially in children.
In many cases, lazy eye is detected only during a routine eye examination.
Amblyopia develops due to abnormal visual development in early childhood.
Main Causes
Children are at higher risk if they:
Common Tests Include:
Doctors recommend a complete eye check-up between ages 3 to 5 for early detection.
Amblyopia treatment focuses on strengthening the weaker eye and improving coordination with the brain.
1. Eyeglasses or Contact Lenses
Correct refractive errors causing vision imbalance.
2. Eye Patching
Covering the stronger eye forces the brain to use the weaker eye.
3. Atropine Eye DropsUsed to temporarily blur vision in the stronger eye.
4. Vision Therapy
Exercises to improve eye coordination and focus.
5. Surgery
Recommended in cases of cataract, droopy eyelid, or severe squint.
At ASG Eye Hospitals, pediatric eye specialists provide early diagnosis and customized treatment plans to ensure the best visual outcomes.
If not treated early, amblyopia can lead to:
Amblyopia in Children
Amblyopia usually develops from birth up to 7 years of age. Early treatment is highly effective because the brain is still developing.
