RT Journal Article SR Electronic T1 Stimulation of dopamine receptors (type 2) lowers human intraocular pressure. JF British Journal of Ophthalmology JO Br J Ophthalmol FD BMJ Publishing Group Ltd. SP 909 OP 910 DO 10.1136/bjo.69.12.909 VO 69 IS 12 A1 Q A Mekki A1 P Turner YR 1985 UL http://bjo.bmj.com/content/69/12/909.abstract AB The interaction between bromocriptine and metoclopramide on intraocular pressure (IOP), pupil diameter, and other parameters were studied in healthy volunteers. Pupil diameter was not affected by both treatments and only bromocriptine lowered IOP. Prior treatment with metoclopramide blocked the IOP-lowering effect of bromocriptine. It is concluded that bromocriptine lowers IOP by stimulation of dopamine-2 receptors.
