intraocular pressure
Học thuậtThân thiện
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
- 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
