What is amblyopia?
Amblyopia means lazy eye. The brain and the eye work together to produce vision. Light enters the eye and is changed into nerve signals that travel along the optic nerve (sight nerve) to the brain. Amblyopia is the medical term used when the vision in one of the eyes is reduced because the eye and the brain are not working together properly. The eye itself looks normal, but it is not being used normally because the brain is favouring the other eye.

How common is amblyopia?
Amblyopia is the most common cause of visual impairment in childhood. The condition affects approximately 2 to 3% of children. Unless it is successfully treated in early childhood, amblyopia becomes irreversible.

What causes amblyopia?
For normal development of vision clear image must be formed in the retina during early childhood. Amblyopia may be caused by any condition that affects normal visual development or use of the eyes that prevents a clear image from forming on the retina of the eye. Amblyopia can be caused by squint. Squint can cause the eyes to cross in (esotropia) or turn out (exotropia). Sometimes amblyopia is caused when one eye is more nearsighted, farsighted, or astigmatic (cylindrical power of glasses) than the other eye. Occasionally, amblyopia is caused by other eye conditions such as cataract or corneal opacity which is either present at birth or develops during early childhood.
