amblyopia

reduction in vision in one or both eyes due to abnormal visual experience in early childhood, leading to functional changes in the visual centres of the brain. These changes result from eye-related problems that degrade or distort images received by the brain. The most common causes are misalignment of the eyes (strabismus) and uncorrected (usually asymmetric) refractive errors (e.g., farsightedness, nearsightedness, or astigmatism). Other conditions that affect the clarity of vision, such as congenital cataracts, can also cause amblyopia. In each of these situations the brain receives inferior or inappropriate visual information, which it suppresses over time.
