When you hear intraocular pressure, the fluid pressure inside your eye that helps maintain its shape and function. Also known as eye pressure, it's something most people never think about—until it’s too high. That’s when it becomes a silent threat. Unlike blood pressure, you can’t feel high intraocular pressure. There’s no pain, no warning signs. But over time, it can damage the optic nerve and lead to permanent vision loss—often without you realizing it until it’s advanced.
This is why glaucoma, a group of eye diseases that damage the optic nerve, often due to high intraocular pressure is called the "silent thief of sight." It doesn’t show up in routine checkups unless your doctor measures your eye pressure. And even then, normal pressure doesn’t mean you’re safe—some people develop glaucoma with pressure in the normal range. On the flip side, having high pressure doesn’t always mean you have glaucoma. That’s called ocular hypertension, elevated eye pressure without optic nerve damage. It’s a risk factor, not a diagnosis. But it’s a red flag that needs monitoring.
What raises intraocular pressure? It’s usually about fluid balance. Your eye makes a clear fluid called aqueous humor. It flows in, nourishes parts of the eye, then drains out. If drainage gets blocked or slowed—because of age, genetics, injury, or even certain medications like steroids—pressure builds. That’s why people with a family history of glaucoma, African or Hispanic heritage, diabetes, or long-term steroid use need regular eye checks. Even something as simple as sleeping face-down or doing inverted yoga poses can temporarily spike pressure in sensitive individuals.
Doctors measure intraocular pressure with a quick, painless test called tonometry. It’s part of any comprehensive eye exam. If numbers are high, they’ll check the optic nerve, visual field, and cornea thickness. Treatment isn’t always medicine. Sometimes, it’s just watching and rechecking every few months. But if pressure stays high, eye drops are the first line of defense—they help reduce fluid production or improve drainage. Laser procedures and surgery come in when drops aren’t enough. The goal isn’t just to lower pressure—it’s to preserve your vision before it’s too late.
The posts below give you real, practical insights into how eye pressure connects to other health issues. You’ll find how certain medications—like diuretics or NSAIDs—can affect fluid balance in the eye. You’ll see how conditions like kidney disease or thyroid disorders can influence pressure levels. And you’ll learn what steps you can take to protect your eyes, whether you’re managing a chronic condition or just want to stay ahead of the game. This isn’t just about numbers on a screen. It’s about keeping your vision clear for years to come.

Glaucoma is a silent eye disease caused by optic nerve damage, often linked to elevated eye pressure. Early detection through regular eye exams can prevent vision loss. Treatment focuses on lowering pressure to slow progression.
