Systemically-administered noradrenaline lowers intraocular pressure; isoproterenol, similarly administered, has an intraocular pressure-raising effect. Unless extremely low doses are used, these effects will be marked by opposite changes in arterial perfusing pressure. Intraocular pressure-regulating mechanisms carry both alpha- and beta-receptors. Stimulation of alpha-receptors decreases intraocular pressure, while stimulation of beta-receptors increases intraocular pressure. Intraocular pressure is under tonic sympathetic influence.
全身给药的去甲肾上腺素可降低眼压；同样给药的异丙肾上腺素则有升高眼压的作用。除非使用极低剂量，这些效应将伴随着动脉灌注压的相反变化而显著出现。眼压调节机制同时具有α和β受体。刺激α受体可降低眼压，而刺激β受体则会升高眼压。眼压受持续性交感神经影响。
