Definition

Noun: * The pressure inside the eye: "Intraocular pressure" refers to the fluid pressure maintained within the eyeball. It is a crucial physiological measurement for eye health, primarily regulated by the balance between the production and drainage of a clear fluid called the aqueous humor.

Usage Examples

• Noun:
  • The optometrist measured my intraocular pressure during the routine eye exam.
  • Elevated intraocular pressure is a major risk factor for glaucoma.
  • A normal range for intraocular pressure is typically between 10 and 21 millimeters of mercury (mmHg).

Advanced Usage

• "to have elevated/high intraocular pressure": to have a measurement above the normal statistical range.
  • The patient was diagnosed with ocular hypertension after tests showed he had consistently high intraocular pressure.
• "to lower/reduce intraocular pressure": to decrease the fluid pressure inside the eye, often as a medical treatment.
  • The prescribed eye drops are effective in lowering intraocular pressure.

Variants and Related Words

• IOP (n): A common medical abbreviation for "intraocular pressure".
  • The doctor noted the patient's IOP was 18 mmHg.
• Ocular hypertension (n): A condition characterized by elevated intraocular pressure without detectable optic nerve damage or vision loss.
• Tonometry (n): The procedure or test used to measure intraocular pressure.

Synonyms

• Eye pressure: A common, non-technical synonym.
  • The test checks your eye pressure.

Related Terms (Not Synonyms)

• Glaucoma (n): A group of eye diseases often associated with, but not exclusively caused by, increased intraocular pressure, leading to optic nerve damage.
• Aqueous humor (n): The clear fluid in the front part of the eye whose production and drainage regulate intraocular pressure.

Noun

1. pressure exerted by the fluids inside the eyeball; regulated by resistance to the outward flow of aqueous humor
   • glaucoma can result from increased intraocular pressure
