What is considered high intraocular pressure?
Measuring Eye Pressure Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal. When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.
What is normal eye pressure after cataract surgery?
The elevation in IOP typically peaks at 3 to 7 hours after cataract extraction, persists for the first 24 hours, and returns to nearly normal levels within 48 hours. Numerous studies have documented this rise in IOP after cataract surgery, and it can be as high as 40 mm Hg in some cases.
How do you reduce intraocular pressure after cataract surgery?
The best treatment is to taper or stop the topical steroid medications and use other agents such as NSAIDs to control any residual inflammation. The addition of topical IOP-lowering medications is also useful in these patients.
What is intraocular pressure, and why does it matter?
Normal intraocular pressure helps support the shape of the eye, which in turn supports the 2 million parts of the eye that help you see. High pressure. When the fluid in the front of your eye doesn’t drain as well as it should, or your eye is producing too much fluid, pressure can get too high. Your doctor may call this ocular hypertension.
What is considered dangerously high eye pressure?
Anything below 12mm Hg is indicative of hypotony, or low eye pressure, and anything above 22mm HG may signal intraocular hypertension, or high eye pressure. While high eye pressure is not inherently dangerous, it increases your risk of developing glaucoma, a progressive eye disease that can result in blindness.
How to check intraocular pressure?
A tonometry test measures your intraocular pressure. It’s like pressing a balloon to check for air. It shows how firm your eyeball is with the same measurement units used to check blood pressure. The normal range for intraocular pressure is about 10-20 mm HG. The test is done in a couple of ways.
