Eye to eye
At this time of reflection on the past year I have been thinking about lectures I have attended and articles I have read in the past 12 months that profoundly changed my way of thinking about patient treatments. The area of biggest change in thinking has been in the treatment of “lazy eye” (properly called amblyopia) and squint.
Many years ago Nobel Prize-winning research found the vision area of the brain mainly consists of cells that need input from both eyes to function properly. For some reason in “lazy eye” there is a miss-match of information being sent to the brain from our two eyes and “binocular competition” develops. Our brains don’t like this and to eliminate the competition the brain suppresses, or switches off, the information being sent from one eye. This can be by allowing one eye to turn in or out so this “squinting” eye is not seeing the same as the other eye. It can also be by switching off the connections within the brain for information from one eye.
