Glaucoma is a leading cause of blindness with no known cure. Unfortunately, its effects cannot be reversed. Managing glaucoma requires lifelong medical care.
The good news is that with proper treatment, the effects of glaucoma can be mitigated and the disease’s progression can be slowed. Treatment options for glaucoma typically include eye drops, laser surgery, conventional surgery, or a combination of these approaches. Each has its own benefits and risks; your doctor can help determine the best course of action for your eyes.

You deserve clear vision. We can help.
The board-certified surgeons at NVISION have performed over 2.5 million procedures. Your journey to better vision starts here.
What Is Glaucoma?
With each blink, your eyes adjust fluid levels. New fluid comes in, and old fluids are recycled. When the system breaks, fluids build up within the eye. Pressure rises, and the optic nerve is compressed. In time, this can compromise your vision.
Glaucoma is the second leading cause of blindness globally, says the Centers for Disease Control and Prevention. The disease is dangerous because:
- It is painless. We often use pain to warn us that something has gone wrong in our bodies. In the early stages, glaucoma does not hurt at all.
- It is gradual. You will not wake up one morning and discover that your sight is gone. Instead, you will lose it in small steps that are easy to ignore.
- It is permanent. The sight you lose due to glaucoma will not come back.
Early glaucoma treatment is critical, as it can help you preserve what you have without losing yet more eyesight. Thanks to advances in treatment, glaucoma no longer means blindness for most people. But even with treatment, glaucoma can have serious consequences.
According to the Glaucoma Research Foundation, about 10 percent of people who get glaucoma treatment still experience vision loss.
How Is Glaucoma Treated?
The goal of glaucoma treatment is to amend the fluid imbalance within your eyes. When your eyes can drain properly, the pressure drops. That allows your optic nerve to escape further damage, so you will not lose any more vision.
Frontline treatment for glaucoma involves eye drops. Many different versions exist, including:
- Alpha-adrenergic agonists.
- Beta blockers.
- Carbonic anhydrase inhibitors.
- Cholinergic agents.
- Prostaglandins.
- Rho kinase inhibitors.
Most of these drops work by either increasing outflow of liquids or reducing fluid production. You will use them at least once, if not several, times each day. You can’t skip a dose, or severe symptoms can return.
Glaucoma eye drops can cause side effects, says the American Academy of Ophthalmology, including:
- Blurry vision.
- Changes in pulse and heartbeat.
- Energy level changes.
- Dry mouth.
- Itchiness around the eyes.
- Eye redness.
- Stinging sensations.
If you are struggling with side effects from one type of drop, another may be a better option for you. Talk to your doctor before stopping or modifying any treatment for your glaucoma.
If you can’t tolerate drops, your doctor might recommend laser trabeculoplasty. Your surgeon uses a laser to optimize how well your eye drains, and if it’s done properly, you may not need eye drops. This is not a cure for glaucoma, as the effect can wear off and require another surgery. But it could be a good option for those who just can’t handle medication management.
Another option for glaucoma treatment is the newly FDA-approved iDose TR, which provides continuous, around-the-clock medication adherence. This 24/7 adherence eliminates the need to remember daily doses or worry about missed applications, making it easier to maintain stable eye pressure at all times.
Conventional surgery is also an option for people with glaucoma. Surgeons implant shunts to improve drainage, or they snip away at the bits that are blocking drainage channels.
The Glaucoma Research Foundation says only 11% of people with glaucoma choose surgery. The rest use drops or lasers instead. But surgery can be helpful for some people who do not benefit from those other forms of care.
Sometimes, people can manage their glaucoma with conservative means like eye drops for years before symptoms worsen. At that point, an ophthalmologist may recommend laser or traditional surgery.
Innovations in Glaucoma Treatment
One area that shows promise for innovative glaucoma treatment is gene therapy. Researchers from the University of Bristol Medical School conducted a study showing that sight-deterioration from glaucoma could be improved with gene therapy.
The team employed CRISPR gene editing to inactivate the Aquaporin 1 gene in the ciliary body, which generates fluid to maintain normal eye pressure. The result was reduced IOP. While this is still not a cure for glaucoma, the researchers are collaborating with industry partners to move towards clinical trials soon.
Researchers at the Harvard Medical School also manipulated retinal cells to recapture youthful gene function and restore vision in mice. This was the first successful reversal of glaucoma-induced vision loss and glaucoma damage.
Most other treatments seek to stem its progression. This gene therapy may reverse cell aging successfully and potentially revolutionize eye treatment. Clinicians are hopeful to begin clinical trials soon if further animal testing confirms research findings.
In 2020, the U.S. Food and Drug Administration (FDA) approved the first biodegradable intracameral sustained-release implant for DURYSTA (a prostaglandin analog) from Allergan plc. The new drug application (NDA) reduces IOP in patients with ocular hypertension and open-angle glaucoma. It is an important breakthrough, offering a viable option for people who have problems with topical eye drops.

At-Home Glaucoma Treatments
There are plenty of things you can do at home to help address your glaucoma. You can use your eye drops, for example. Unfortunately, there are no DIY or ‘at-home’ treatments that can cure glaucoma.
Experts agree that a diet rich in fruits and vegetables is beneficial for overall health, including for those with glaucoma, but there is no specific diet to control the condition, and claims of a food-based “glaucoma cure” are unfounded.
Exercise could be helpful as you work on your glaucoma. The Glaucoma Research Foundation says, for example, that people walking briskly four times per week for 40 minutes per session reduced eye pressure enough to eliminate the need for one type of medication.
But some types of exercise, including some yoga poses, could be dangerous for people with glaucoma. Make sure you are breathing evenly and deeply while you exercise, as holding your breath puts pressure on your eyes.
It’s smart to talk with your doctor about your exercise plans before you begin a new exercise regimen or diet.
Is a Cure for Glaucoma Possible?
Although there is currently no current cure for glaucoma, ongoing research offers hope for the future. The National Glaucoma Foundation notes that advancements aimed at restoring vision may take years to develop, as the work is both complex and time-intensive. Nonetheless, progress is being made.
In the meantime, it’s essential to maintain regular communication with your doctor. Adhere to prescribed treatments and discuss any concerns or changes in your condition to ensure your care remains effective.
Significant strides have been made in managing glaucoma. Early diagnosis and timely treatment can dramatically slow its progression and reduce the risk of severe vision loss. Regular eye exams are crucial for achieving the best possible long-term outcome.
