The near response complex comprises three elements: accommodation, convergence, and pupillary constriction. The synkinesis between vergence and accommodation is well understood functionally, if not neuroanatomically. The latencies of near response components were measured in four healthy, experienced subjects to determine how the pupillary component is mediated. Addition of disparity stimulus to blur, yielding a near stimulus, reduces the latency of vergence eye movements and of accommodation by an amount that is significantly greater than the corresponding reduction in pupil latency. None of the existing hypotheses: vergence-pupil, accommodation-pupil or symmetric dual interaction, can account for this difference. Therefore, we present a new hypothesis: asymmetric dual interaction between accommodation and vergence.
调节、集合和瞳孔收缩。尽管在神经解剖学上尚未明确，但集合与调节之间的联带运动在功能上已得到充分理解。对四名健康且经验丰富的受试者测量了近反射成分的潜伏期，以确定瞳孔成分是如何介导的。在模糊刺激中加入视差刺激，产生近刺激，可使集合眼球运动和调节的潜伏期缩短，缩短幅度明显大于瞳孔潜伏期的相应缩短幅度。现有的任何假设：集合-瞳孔、调节-瞳孔或对称双相互作用，都无法解释这种差异。因此，我们提出一个新的假设：调节与集合之间的不对称双相互作用。
