Causes of Lazy Eye Syndrome: Understanding Amblyopia
Amblyopia, often called lazy eye, is reduced vision caused by abnormal visual development in childhood. It is not laziness and may affect one or, less commonly, both eyes. Children can appear to see normally, so screening and a full eye examination matter.
What causes amblyopia?
- Refractive difference: one eye may be more short-sighted, long-sighted or astigmatic than the other.
- Strabismus: an eye that turns can lead the brain to rely on the better-aligned eye.
- Visual obstruction: cataract, drooping eyelid or another condition may block a clear image during development.
These causes require different treatment. An eye turn and amblyopia are related but are not the same diagnosis.
Signs and diagnosis
Possible signs include an eye turning, squinting, closing one eye, head tilting or difficulty judging depth. Many children have no obvious sign. Assessment may include age-appropriate vision tests, refraction after dilating drops, eye alignment and examination of the eye’s structures.
Treatment
Treatment addresses the underlying optical or eye condition and encourages use of the weaker eye. It may involve glasses, patching the stronger eye, atropine drops or treatment of cataract or strabismus where clinically indicated. The schedule must be prescribed and monitored; excessive patching or unsupervised drops can cause harm.
Earlier diagnosis generally offers more opportunity during visual development, but age alone should not be used to deny assessment. Response and duration vary, and recurrence monitoring may be needed.
