Contrast sensitivity in meridional amblyopia.
Contrast (modulation) sensitivities for gratings of various spatial frequencies and orientations have been determined for meridional amblyopes. The entire contrast sensitivity function is reduced for gratings oriented in the amblyopic meridian. Therefore, neural elements that process a broad range of spatial frequencies are affected by meridional amblyopia.
