Ever noticed halos around lights, sudden blurry patches, or a dull ache behind your eyes? Those can be signs of raised eye pressure — the main risk factor for glaucoma, which can quietly eat away your vision. Here you'll get clear, practical steps to spot issues early, get an accurate check, and protect your sight.
Eye pressure, or intraocular pressure (IOP), is the fluid pressure inside your eye. Your eye constantly makes and drains fluid; when drainage slows or production rises, pressure climbs. High IOP doesn't always cause pain, but over time it can damage the optic nerve and reduce peripheral vision.
Common warning signs include blurred vision, rainbow halos around lights, eye pain or headache, and sudden loss of vision in severe cases. Still, many people have high eye pressure with no symptoms, which is why routine eye checks matter — especially if you fall into a higher-risk group.
Risk factors that raise your odds: age over 60, a family history of glaucoma, high myopia (near-sightedness), long-term steroid use, prior eye injury, and some medical conditions like diabetes or high blood pressure. Smoking and poor control of systemic blood pressure can make eye health worse.
An eye doctor measures IOP with tonometry. The most common is the puff test (air tonometry) or a quick contact probe after numbing drops. They may also measure corneal thickness and check the optic nerve with imaging. These tests take minutes and give a clear picture: one normal reading doesn't guarantee safety, so follow your doctor's recommended schedule.
Treatment focuses on lowering pressure enough to protect the optic nerve. First-line care is usually prescription eye drops that reduce fluid production or improve drainage. If drops don't work or cause side effects, laser treatment or surgery can help. Your ophthalmologist will pick the approach based on your pressure level, optic nerve health, and daily life.
Keep up with prescribed eye drops — missing doses reduces effectiveness. Manage systemic health: control blood pressure and blood sugar, quit smoking, and stay active. Wear protective eyewear during sports or risky jobs to avoid injury that can raise IOP later. Also, tell your doctor about steroid medicines you take; some raise eye pressure and need monitoring.
Proper eye-drop technique helps: tilt head back, pull down lower lid, drop one dose, close eye and press inner corner for a minute. If using multiple drops, wait five minutes between them. Bring a list of medicines to regular appointments.
Get regular eye exams if you’re over 40 or have any risk factors. If you notice sudden vision changes, severe pain, or nausea with eye pain, seek emergency care — acute angle-closure glaucoma is sight-threatening and needs immediate treatment.

As a blogger, I've recently come across the role of brinzolamide in treating ocular hypertension. Brinzolamide is a carbonic anhydrase inhibitor eye drop that helps reduce intraocular pressure (IOP), a significant risk factor for glaucoma. By limiting the production of aqueous humor, brinzolamide effectively lowers IOP and provides relief to patients suffering from ocular hypertension. This medication is often used as an alternative or adjunct to other treatments, like prostaglandin analogs, for better management of the condition. Overall, brinzolamide plays a crucial role in managing ocular hypertension and preventing further complications, such as vision loss.
