Can amblyopia affect the brain?

Amblyopia is reduced vision in one eye caused by abnormal visual development early in life. Early diagnosis and treatment can help prevent long-term problems with a child's vision. A lazy eye develops because of abnormal visual experience early in life that changes the nerve pathways between a thin layer of tissue (retina) at the back of the eye and the brain. The weaker eye receives fewer visual signals. The brain suppresses or ignores input from the weaker eye. Does it affect the brain? Can amblyopia affect the brain?

@gavan Hello, Amblyopia results from developmental problems in the brain. When the parts of the brain concerned with visual processing do not function properly, problems ensue with such visual functions as the perception of movement, depth, and fine detail. According to the research striking changes in neuron activity are seen. Normal visual motion perception relies on neurons that integrate information about the position of moving objects as they cross the visual image. The ability to integrate motion information was defective in neurons driven through the affected eye. The study shows that amblyopia results from changes in the brain that extend beyond the primary visual cortex
