The effect of unilateral decentralization on the circadian rhythm of IOP was examined in rabbits to determine whether postganglionic sympathetic nerves to the eye can play a role in regulating the circadian rhythm of IOP in the absence of input from the central nervous system. Decentralization produced a marked reduction of the dark phase increase of IOP, but had little effect on IOP during the light phase. Therefore, circadian signals from the central nervous system, which contribute to the dark phase increase of IOP, arrive at the cervical ganglia by way of preganglionic fibers of the sympathetic chain and travel to the eye through postganglionic adrenergic nerves.
在兔子身上研究了单侧去神经支配对眼压昼夜节律的影响，以确定在没有中枢神经系统输入的情况下，眼的节后交感神经是否能在调节眼压昼夜节律中发挥作用。去神经支配使眼压在暗期的升高显著降低，但对明期的眼压影响不大。因此，来自中枢神经系统的昼夜节律信号，它促成了眼压在暗期的升高，通过交感神经链的节前纤维到达颈神经节，并通过节后肾上腺素能神经传导至眼。
