Glaucoma treatment: practical options to protect your vision

Glaucoma steals sight slowly, often without pain. The good news: early treatment usually slows or stops vision loss. If you’ve been told you have glaucoma or are at risk, here’s a clear, practical rundown of what works, what to expect, and questions to ask your eye doctor.

Most people start with eye drops. Drops lower pressure inside the eye (IOP), the main modifiable risk factor. Common classes include prostaglandin analogs (once daily, strong IOP drop), beta-blockers (twice daily, watch heart and breathing effects), alpha agonists, carbonic anhydrase inhibitors, and newer Rho-kinase agents. Each has different side effects: redness, stinging, dry eyes, slow heartbeat, or local irritation. Try one class at a time and give it several weeks; report problems to your doctor so changes can be made.

Can laser help? Yes. Laser trabeculoplasty uses a targeted beam to improve fluid outflow and lower IOP. It’s often an option when drops aren’t enough or adherence is poor. Many patients get months or years of benefit; some still need drops later. Laser is quick, done in clinic, and has a low complication rate.

Surgery and newer procedures

If drops and laser don’t control pressure, surgery is next. Traditional trabeculectomy and tube shunts are proven at lowering pressure for advanced disease. Minimally invasive glaucoma surgeries (MIGS) are gentler, with faster recovery and fewer risks, but they may lower pressure less. Choice depends on disease stage, eye anatomy, and overall health. Ask your surgeon about expected pressure targets, recovery time, and long-term follow-up.

Daily habits and monitoring that matter

Medication adherence is the single biggest factor patients control. Use reminders, link drops to daily routines, or ask about combination drops to simplify treatment. Regular eye exams with visual field tests and optic nerve photos are essential; glaucoma can progress without obvious symptoms. Control blood pressure, avoid tobacco, and talk to your doctor about sleep apnea or steroid use, which can affect pressure. Exercise helps, but head-down yoga poses can raise eye pressure temporarily.

Side effects, costs, and access often shape real-world choices. Generic drops lower cost. Some patients qualify for assistance programs or mail-order pharmacies. If you struggle with technique, ask for a demonstration or use an applicator. For any sudden pain, redness, or rapid vision change, get urgent care from an eye specialist.

Questions to bring to your appointment: What is my target IOP? How will we measure progress? What are the side effects of this option? If surgery is recommended, what are the risks and recovery steps? Keep a simple log of your drops and symptoms — it helps your doctor make better decisions.

Glaucoma treatment is a long-term partnership. With the right plan and regular follow-up, many people keep useful vision for life. Work with your eye care team, ask clear questions, and focus on practical steps you can control every day.
