对比敏感度作为一个函数的光栅刺激的方向是由行为方法确定了四个恒河猴。其中两只猴子是在正常的双眼经验下饲养的，有球面屈光不正，并表现出正常的斜视效果。另外两只在一只眼皮被缝合的情况下饲养的猴子（在这些实验中仍然是缝合的），在未被剥夺的眼睛中表现出散光屈光不正，光栅对比敏感度作为方向的函数，与它们散光的主经络相关。对照实验表明，经向弱视不是由于未矫正的屈光不正。反应时间测量的对比灵敏度的阈上光栅模式表明，子午弱视不存在高对比度光栅。
Contrast sensitivity as a function of the orientation of a grating stimulus was determined by behavioral methods for four rhesus monkeys. Two of the monkeys had been reared with normal binocular experience, had spherical refractive errors, and showed a normal oblique effect. The other two monkeys which had been reared with one eyelid sutured (which was still sutured during these experiments), showed astigmatic refractive errors in the non-deprived eye and grating contrast sensitivity as a function of orientation that was correlated with the principal meridians of their astigmatism. Control experiments showed that the meridional amblyopia was not due to an uncorrected refractive error. Reaction time measures of contrast sensitivity for suprathreshold grating patterns showed that meridional amblyopia was not present for high contrast gratings.
