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]
Cataracts: Cloudiness over the eye's lens, cause blurring of vision, halos around lights, and sensitivity to glare. [5] It is also the main cause of blindness worldwide. [2] Glaucoma: Increased intraocular pressure (pressure in the eye) cause progressive optic neuropathy that leads to optic nerve damage, visual field defects and blindness. [6]
In open-angle glaucoma, the draining is impeded, causing the liquid to accumulate and pressure inside the eye to increase. This elevated pressure can damage the optic nerve. In closed-angle glaucoma, the drainage of the eye becomes suddenly blocked, leading to a rapid increase in intraocular pressure. This may lead to intense eye pain, blurred ...

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]
Adding weight increases your heart rate more than regular walking, providing a more intense cardiovascular workout. This can improve heart health, increase stamina, and better cardiovascular fitness.
Contact lenses and certain medications can also cause dry eye, she says, adding: “If you think you are experiencing dry eye, talk to your ophthalmologist about the best treatment options for you.”
