Abnormal vision in childhood can affect brain functions

The researchers from the University of Waterloo, British Columbia, and Auckland uncovered differences in how the brain processes visual information in patients with various types of lazy eye. In doing so, they are the first to demonstrate that the brain can divert attention away from a lazy eye when both eyes are open.

"Current treatments for lazy eye primarily target the early stages of visual processing within the brain," said Ben Thompson, a professor in Waterloo's School of Optometry and Vision Science."The results from this study show us that new treatments should also target higher-level processes such as attention."
