Normal Intraocular Pressure in Man
Abstract
Whereas the values of 120/70 mm Hg are universally recognized as being normal for the parameter of systemic blood pressure, the value for ‘normal intraocular pressure’ remains very vague. Indeed, values between 7 and 21 mm Hg are often considered normal. However, a careful review of the literature and original data reported here suggest that the intraocular pressure in normal subjects, although dynamic, is a more accurate parameter than is generally expected. The normal value during the day in healthy, young adults is about 12 ± 2 mm Hg, and it increases by 1mm Hg per decade after 40 years of age.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The normal range for intraocular pressure is reportedly 7-21 mmHg, and daily fluctuations in intraocular pressure can show an approximate range of 3-7 mmHg.
“The normal range for IOPs is reportedly 7–21 mmHg, and daily fluctuations in IOP can show an approximate range of 3–7 mmHg [22–25].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
