Contour integration in anisometropic amblyopia

Contour integration was measured in a group of anisometropic amblyopes to test the idea recently put forward that positional uncertainty sets a fundamental limit to contour integration in amblyopia, Anisometropic amblyopia, unlike strabismic amblyopia, has little or no positional uncertainty once the initial filtering loss has been taken into account, Therefore, according to the explanation put forward to explain strabismic amblyopia, anisometropes should exhibit normal contour integration, We show that this expectation is realized for five of our six anisometropic amblyopes.
