Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [1] [2]For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3]
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 [ 17 ] despite the slower production of aqueous humour. [ 18 ]
A study with 1636 persons aged 40-80 who had an intraocular pressure above 24 mmHg in at least one eye but no indications of eye damages showed that after five years 9.5% of the untreated participants and 4.4% of the treated participants had developed glaucomatous symptoms, meaning that only about one in ten untreated people with elevated ...
Here's how to distinguish "sundowning"—agitation or confusion later in the day in dementia patients—from typical aging, from doctors who treat older adults.

Glaucoma is an eye disease often characterized by increased pressure within the eye or intraocular pressure (IOP). [61] Glaucoma causes visual field loss as well as severs the optic nerve. [ 62 ] Early diagnosis and treatment of glaucoma in patients is imperative because glaucoma is triggered by non-specific levels of IOP. [ 62 ]
For the study, researchers analyzed data from 445 adults aged 65 and up who lived in a community. The participants were assessed for motoric cognitive risk syndrome (MCR), which is considered a ...
Visual snow syndrome is often linked to heightened neural sensitivity in the visual system and may require diagnosis and treatment, as it could be associated with underlying eye conditions or neurological disorders. [citation needed] In summary: Visual snow as a temporary occurrence under certain conditions is normal and doesn't require ...
