Steroid-Induced Glaucoma: Causes, Risks, and What You Can Do

When you take steroid-induced glaucoma, a type of eye pressure damage caused by long-term use of corticosteroid medications. It's not the same as regular glaucoma—it shows up because of drugs you might be taking for asthma, arthritis, or autoimmune conditions. This isn't rare. People on daily prednisone for months, or using steroid eye drops for chronic inflammation, can quietly develop rising pressure inside their eyes. And if no one checks, it can lead to permanent vision loss before you even notice symptoms.

corticosteroids, powerful anti-inflammatory drugs like prednisone, dexamethasone, and hydrocortisone. Also known as steroids, they’re lifesavers for many—but they don’t come without trade-offs. One of the quietest risks? Eye pressure. These drugs interfere with how fluid drains from your eye, causing pressure to build up behind the lens. It’s not about using them once or twice. It’s about duration and dosage. Someone on 20mg of prednisone daily for six months has a much higher chance than someone using a short course for a flare-up. And it’s not just pills. Steroid eye drops, nasal sprays, and even skin creams can contribute if used long-term.

eye pressure, the force of fluid inside the eye, measured in millimeters of mercury (mmHg). Normal is under 21. When it climbs above 25 and stays there, damage to the optic nerve can begin—slowly, silently. You won’t feel it. No pain. No redness. No blurriness at first. That’s why regular eye exams are critical if you’re on steroids. A simple tonometry test can catch it early. People with a family history of glaucoma, diabetics, or those with thin corneas are at even higher risk. But anyone on long-term steroids should get checked at least once a year—or every six months if they’re on high doses.

What can you do? First, don’t stop your meds without talking to your doctor. But do ask: "Could this be affecting my eyes?" Second, get your eyes checked by an optometrist or ophthalmologist who knows about steroid risks. Third, if pressure rises, there are drops that can help lower it—sometimes even without stopping the steroid. And if you’re on steroid eye drops for more than a few weeks, your doctor should be monitoring you closely.

The posts below cover real-world cases, practical steps to protect your vision, and how common medications like prednisone connect to eye health. You’ll find advice on spotting early signs, when to push for testing, and how to balance treating your condition without risking your sight. This isn’t just about drugs—it’s about staying in control of your health while using them.
