Glaucoma Treatment: Clear Steps to Lower Pressure and Save Vision

Glaucoma is a group of eye conditions that damage the optic nerve, usually from high eye pressure. If untreated, it can cause permanent vision loss. The good news: treatment can slow or stop damage. Here’s a plain, practical guide to your options and what matters most day-to-day.

First-line care: eye drops and why they matter

Most people start with prescription eye drops. These lower intraocular pressure (IOP) in two ways: reduce fluid production or help fluid drain. Common classes include prostaglandin analogs (once-a-day dosing), beta blockers, alpha agonists, and carbonic anhydrase inhibitors. Drops work well when used consistently. Missed doses let pressure rise and risk permanent loss.

Watch for side effects—eye redness, stinging, or changes in eyelash growth are common with some drops. Systemic effects like tiredness or slowed heart rate can happen with beta blockers. Tell your eye doctor about other medications and health problems before starting drops.

When drops aren’t enough: lasers and surgery

If drops don’t control pressure or cause bad side effects, laser or surgical options come next. Laser trabeculoplasty helps drainage by opening the eye’s drainage meshwork. It’s an outpatient procedure and often lowers pressure for years, but results can fade.

Surgery (trabeculectomy or tube shunts) creates a new drainage path. Newer minimally invasive glaucoma surgeries (MIGS) offer lower risk and faster recovery, often done with cataract surgery. Surgery aims to reduce reliance on drops and protect vision long-term. Discuss pros and cons and likely outcomes with your surgeon.

Oral medications like acetazolamide are used short-term or when rapid pressure drop is needed. They’re not a first choice for long-term use because of side effects like tingling, taste changes, or kidney concerns.

Regular monitoring matters. Your eye doctor will check IOP, optic nerve appearance, and visual fields. Frequency depends on disease stage. Early glaucoma might need checks every 6–12 months; advanced disease needs closer follow-up. Keep copies of test results so you can track trends over time.

Practical daily tips: set alarms for drops, use a calendar or app, and refill prescriptions before you run out. Bring a list of all meds to every visit. If cost is a problem, ask about generic drops, patient assistance programs, or trusted Canadian/online pharmacies—only after confirming the prescription and pharmacy legitimacy with your provider.

Think about lifestyle too. Regular moderate exercise can lower IOP slightly for many people. Avoid activities that spike pressure (heavy head-down yoga poses, certain breath-holding). Sleep with your head slightly elevated if advised. Lastly, always talk to your ophthalmologist before changing treatment—glaucoma needs steady care to protect your sight.
