Many patients with glaucoma ask the same question. “Is there anything else I can do?” It is a fair question. Glaucoma is a lifelong condition. Eye drops must be used every day. Pressure checks happen every few months. And despite doing everything right, some patients still see slow progression.
The honest answer is yes. There are things you can do beyond your drops and your clinic visits. But some of them can actually harm you. And some of what sounds helpful is not backed by good evidence. Dr Shibal Bhartiya explains.
This article walks you through the most common complementary and alternative therapies for glaucoma, what the research says, and how to think about them safely. It is not a substitute for your glaucoma specialist’s advice. It is meant to help you have a better-informed conversation.

What Does “Complementary” Mean in Glaucoma Care?
Complementary therapies are used alongside conventional treatment. Alternative therapies are used instead of it. In glaucoma, this distinction matters enormously.
Glaucoma causes irreversible vision loss. Delaying or replacing proven treatment with an unproven one can cost you your sight permanently. So if something works in this space, it works as an addition to your drops, laser, or surgery. Never as a replacement.
Between 5 and 10 percent of glaucoma patients use some form of complementary or alternative medicine. Studies suggest that almost 60 percent of those patients do not tell their doctor. That silence can be dangerous. Some supplements interact with glaucoma medications. Some practices raise eye pressure significantly. Your glaucoma specialist needs to know what you are doing.
Why Lifestyle May Matter More Than We Once Thought
Before going through specific therapies, it helps to understand why lifestyle might matter at all in glaucoma.
Glaucoma was once seen as a pressure problem. Lower the pressure, protect the nerve. That picture is now more complicated.
Research increasingly shows that glaucoma behaves as a neurodegenerative disease. The nerve cells that die in glaucoma are similar to neurons lost in conditions such as Alzheimer’s disease. Chronic stress, poor sleep, metabolic dysfunction, and low-grade inflammation can all accelerate this process. Addressing these factors may help slow damage. It will not reverse what is already lost. But slowing damage matters greatly when the disease lasts a lifetime.
Stopping smoking is the most important single intervention to slow progression of disease.
My own research, published over more than two decades in peer-reviewed journals, has explored this connection in depth. A 2024 paper I co-authored in the Journal of Current Glaucoma Practice examined how allostatic load, the cumulative biological burden of chronic stress on the body, may play a role in glaucoma. When your body is under long-term stress, cortisol stays elevated, inflammation builds, and the protective systems for your optic nerve begin to fail. The paper concluded that reducing this stress burden through lifestyle changes should form part of a holistic glaucoma plan.
A 2025 editorial I co-authored with Dr Syril Dorairaj of Mayo Clinic, published in the same journal, further explored how newer metabolic therapies, including GLP-1 receptor agonists, may reshape how we think about glaucoma beyond eye pressure alone.
My earlier review of the field, published in 2014, found that most complementary therapies lacked solid evidence at the time. The call then was for better research looking beyond just pressure. That research is now arriving. The picture is more nuanced than it was a decade ago.

Mind-Body Practices: Where the Evidence Is Strongest
Meditation and Breathing Exercises
This is where the most encouraging evidence lives.
Meditation, specifically slow, diaphragmatic breathing and mindfulness-based practices, has been shown to reduce eye pressure through several biological pathways. It lowers cortisol. It activates the parasympathetic nervous system, which counteracts the stress response. It reduces inflammation. These are measurable changes, not vague wellness claims.
One well-conducted trial found that patients who added a three-week programme of meditation and breathing exercises to their existing glaucoma drops saw eye pressure fall by about 25 percent compared to those on drops alone. That is a clinically meaningful number.
Beyond pressure, regular meditation may reduce the anxiety of living with a chronic, silent disease. It may improve sleep quality. It may reduce the biological stress that compounds glaucoma damage over time.
What is safe: Guided mindfulness meditation, diaphragmatic breathing, alternate-nostril breathing (Anulom Vilom), and slow pranayama are all considered safe for glaucoma patients.
What to avoid: Forceful breathing exercises such as Kapalbhati and Bhastrika work like the Valsalva manoeuvre. They raise abdominal and chest pressure sharply, and this raises eye pressure. These should be avoided.
Yoga: The Right Poses and the Wrong Ones
Yoga is popular, and the question comes up often. The answer depends entirely on which type of yoga.
Yoga that focuses on breathing, slow movement, and relaxation is likely beneficial. It reduces stress, improves circulation, and may support better sleep. Some studies have found that specific slow yoga breathing programmes reduce intraocular pressure in glaucoma patients.
However, certain yoga postures are directly harmful to glaucoma patients. Head-down postures increase the pressure inside the eye rapidly and significantly. This includes:
- Shirshasana (headstand)
- Any handstand or shoulder stand
- Downward dog held for long periods
- Forward folds that place the head below the heart for extended time
Avoid these positions entirely if you have glaucoma or are a glaucoma suspect.
If you practice yoga, tell your instructor that you have glaucoma. Ask them to modify or omit all head-down postures. Do not assume that a yoga teacher will know this without being told.
Aerobic Exercise
Regular moderate aerobic exercise, walking, cycling, swimming, has been shown to lower eye pressure in some studies. The effect is modest but consistent. Exercise also reduces systemic inflammation, improves cardiovascular health, and supports better metabolic function. All of these benefit the optic nerve indirectly.
However, high-intensity isometric exercise such as heavy weightlifting can cause temporary pressure spikes during exertion. In pigmentary glaucoma specifically, vigorous exercise can trigger a burst of pigment release that raises eye pressure sharply.
The practical advice: regular walking and moderate aerobic activity are beneficial and should be encouraged. Heavy resistance training and competitive breath-holding sports should be discussed with your glaucoma specialist first.
Herbal and Nutritional Supplements
Ginkgo Biloba
Ginkgo biloba is one of the most studied herbal supplements in glaucoma. Some evidence suggests it may improve blood flow to the optic nerve and has antioxidant properties. A few studies have found modest benefits for visual field stability in patients with normal tension glaucoma.
However, ginkgo biloba interacts with several medications. It can increase bleeding risk and may interact with blood thinners. Tell your glaucoma doctor before starting it.
Bilberry Extract
Bilberry is rich in antioxidants called anthocyanosides. These are thought to protect retinal tissue from oxidative stress. The evidence in glaucoma is limited. However, bilberry is generally well tolerated and has broader eye health benefits. As always, inform your doctor before adding it.
Omega-3 Fatty Acids
Omega-3 fatty acids have well-documented anti-inflammatory properties. They support healthy retinal tissue and may play a role in reducing low-grade inflammation that contributes to glaucoma progression. Good dietary sources include oily fish, walnuts, and flaxseed. Fish oil supplements are widely used, but discuss dosage with your doctor as high doses can affect bleeding.
Niacinamide (Vitamin B3)
Niacinamide, a form of vitamin B3, has attracted significant scientific interest for its potential neuroprotective role in glaucoma. My published work on this topic, “Niacinamide and Neuroprotection: The Glaucoma Holy Grail,” reviewed the emerging evidence. The rationale is compelling: niacinamide supports mitochondrial function in retinal ganglion cells, which are the nerve cells damaged in glaucoma. Clinical trials are ongoing. It is not yet a standard recommendation but represents a genuinely promising area.
What to Avoid
Be cautious with any supplement that claims to treat glaucoma or lower eye pressure on its own. No supplement has been proven to replace drops or surgery. Some supplements sold online for “eye health” or “vision support” have no quality evidence and may contain ingredients that interact with your medications.
Traditional Systems of Medicine
Ayurveda
Triphala: This traditional herbal combination is used in Ayurveda and has antioxidant properties. Ayurvedic practitioners sometimes recommend it for general eye health. The scientific evidence in glaucoma is limited. If you use it, inform your glaucoma doctor.
Netra Tarpana: This Ayurvedic therapy involves holding medicated ghee around the eyes using a dough ring. It does not lower eye pressure and makes no claim to do so. Some patients find it soothing for dry eye symptoms and eye strain. It is not a glaucoma treatment.
Traditional Chinese Medicine and Acupuncture
Some studies suggest acupuncture may temporarily reduce intraocular pressure and improve eye-related symptoms. The evidence is inconsistent and the effect modest. If you explore acupuncture, seek a trained and registered practitioner. Tell them you have glaucoma and continue your prescribed eye drops throughout.
Acupressure and TCM massage may support relaxation and general wellbeing. Specific herbal TCM formulations should only be used after discussion with your glaucoma specialist, as some Chinese herbal preparations interact with glaucoma medications.
Marijuana (Cannabis)
This question comes up often, especially as cannabis becomes more accessible in various forms.
THC, the active compound in marijuana, does lower intraocular pressure. However, the effect lasts only 3 to 4 hours. To maintain any pressure benefit around the clock, a patient would need to use cannabis six to eight times per day continuously. At that level of use, the systemic side effects, including cardiovascular, cognitive, and psychological effects, are significant. The response rate is also variable. Many patients see little or no pressure reduction.
The current consensus: marijuana is not a reliable or appropriate treatment for glaucoma. It is not a substitute for prescribed eye drops. Some patients use it for sleep or pain, which is a separate decision, but this should be discussed with your doctor, and it must never replace your glaucoma medication.
The Golden Rules for Any Complementary Therapy
Before adding any complementary therapy to your glaucoma management, apply these tests:
Tell your doctor first. Every supplement, herbal remedy, and physical practice should be declared to your glaucoma specialist. This is not about asking permission. It is about safety.
Avoid head-down positions. Whether in yoga, pilates, massage, or any other practice, any prolonged inversion raises eye pressure. If a position puts your head below your heart for more than a few seconds, it is not safe.
Never stop your drops. No complementary therapy is proven to replace prescribed glaucoma medication. Stopping your drops, even briefly, can cause irreversible damage.
Question the claims. If a product claims to cure glaucoma, treat eye pressure naturally, or restore lost vision, it is making claims that science does not support. Complementary therapies support your health. They do not cure glaucoma.
Track your pressure. If you add a new therapy, continue your regular eye pressure checks. This is the only way to know whether it is helping, neutral, or causing harm.
What I Tell My Own Patients
Most of my patients who ask about complementary therapies are not looking to replace their drops. They are looking to feel less passive about a condition that feels out of their control. That desire is healthy and valid.
My honest answer is this. Manage your stress. Walk regularly. Sleep well. Eat a diet rich in antioxidants and omega-3s. Practice slow, mindful breathing, not forceful breathing. Avoid head-down yoga postures. Tell me everything you are taking.
The evidence for most complementary therapies is still limited. But the evidence that chronic stress, poor lifestyle habits, and systemic inflammation worsen glaucoma outcomes is growing. Taking care of your whole body is not an alternative to glaucoma treatment. It is part of it.
Frequently Asked Questions
Can meditation lower eye pressure in glaucoma?
Yes, some studies have found that regular meditation and slow breathing practices reduce intraocular pressure. A well-conducted trial showed a 25 percent pressure reduction in patients who added a structured meditation programme to their drops. The effect depends on consistent practice and proper technique.
Is yoga safe if I have glaucoma?
Some yoga is safe and beneficial. Slow breathing, gentle movement, and relaxation-focused yoga can support overall health. However, all head-down postures, including headstands, shoulder stands, and prolonged downward dog, raise eye pressure significantly and must be avoided.
Can I take supplements instead of glaucoma eye drops?
No. No supplement has been proven to replace prescribed glaucoma drops. Stopping your medication, even to try a supplement, risks irreversible vision loss. Supplements may support your general health but they are not glaucoma treatments.
Does cannabis (marijuana) treat glaucoma?
THC temporarily lowers eye pressure, but the effect lasts only 3 to 4 hours. Continuous use to cover 24 hours causes significant side effects and is not practical or safe. Cannabis is not an approved or reliable treatment for glaucoma.
What supplements are most studied in glaucoma?
Ginkgo biloba, omega-3 fatty acids, bilberry extract, and niacinamide (vitamin B3) have the most published research in the context of glaucoma. None replaces conventional treatment, but some may have a supportive role in overall nerve health when used under medical guidance.
Should I tell my doctor if I am using herbal remedies?
Yes, always. Some herbal preparations interact with glaucoma medications or affect bleeding. Your glaucoma specialist cannot make fully informed decisions about your care without knowing everything you are taking.
