Intraocular Pressure

When talking about intraocular pressure, the fluid pressure inside the eye that keeps its shape and supports proper vision. Also known as IOP, it plays a key role in eye health. Elevated intraocular pressure is the main driver behind glaucoma, a group of diseases that damage the optic nerve and can lead to irreversible vision loss. On the other side, pressure that stays within normal limits but is higher than average is called ocular hypertension, which doesn’t cause symptoms yet raises the risk of turning into glaucoma. Understanding these connections helps you see why regular checks matter.

How Pressure Is Measured and Controlled

Doctors use tonometry, a quick test that gently flattens the cornea to gauge the eye’s internal pressure. Modern devices like non‑contact “air‑puff” tonometers make the process painless, while more precise methods such as applanation tonometry provide exact numbers. Once the baseline is set, treatment options aim to lower pressure and protect the optic nerve. First‑line therapy usually involves prescription eye drops that improve fluid outflow or reduce fluid production. If drops aren’t enough, laser procedures or minimally invasive surgeries can reshape drainage pathways. Lifestyle tweaks—staying active, managing stress, and avoiding excessive caffeine—also contribute to stable pressure levels.

Keeping an eye on intraocular pressure isn’t a one‑time task; it’s an ongoing partnership between you and your eye care team. Home‑monitoring devices are emerging, letting patients track trends between appointments. Knowing your numbers lets you catch spikes early, adjust treatment, and stay ahead of potential damage. Below you’ll find articles that dig into how specific medications affect pressure, tips for safe online purchases of eye‑care drugs, and practical advice on living with glaucoma or ocular hypertension. Dive in to get the facts you need to protect your vision and make informed choices about eye‑pressure management.
