Editing Intraocular pressure (section)

=== Daily variation ===
Intraocular pressure varies throughout the night and day. The diurnal variation for normal eyes is between 3 and 6 [[mmHg]] and the variation may increase in glaucomatous eyes. During the night, intraocular pressure may not decrease<ref name="pmid21330554">{{cite journal |vauthors = Liu JH, Weinreb RN |title = Monitoring intraocular pressure for 24 h |journal = Br J Ophthalmol |volume = 95 |issue = 5 |pages = 599–600 |date = May 2011 |pmid = 21330554 |doi = 10.1136/bjo.2010.199737  |s2cid = 42736853 }}</ref> despite the slower production of aqueous humour.<ref>{{cite journal |last=Brubaker RF |title=Flow of aqueous humor in humans |journal=Invest Ophthalmol Vis Sci |year=1991 |volume=32 |issue=13 |pages=3145–3166 |pmid=1748546}}</ref>   [[Glaucoma]] patients' 24-hour IOP profiles may differ from those of healthy individuals.<ref name="pmid12657596">{{cite journal |vauthors = Liu JH, Zhang X, Kripke DF, Weinreb RN |title = Twenty-four-hour intraocular pressure pattern associated with early glaucomatous changes |journal = Invest.
