Although early studies suggested that marijuana may reduce IOP for a few hours, a host of side effects and practical concerns make its use as a glaucoma treatment controversial at best.

Managing Patient QuestionsBe aware of the marijuana laws in your state.Be ready with an answer be-fore your patients ask questions.Educate and inform interested patients regarding the efficacy, side effects and drug interactions associated with marijuana use.Consider prescribing an oral cannabinoid like Marinol instead.Playing It SafePatients should be careful with any of these supplements because even if they may potentially help, no one knows the proper dosage.Be careful about the purity of the substance in question.Do your homework before proceeding.Encourage a healthy diet with antioxidant and nitrate-rich foods including citrus fruits, peaches, salad, kale and collard greens.Dr. Gamell is an associate professor of ophthalmology at the University of South Florida Health Morsani College of Medicine, and Glaucoma Fellowship Director at the USF Eye Institute in Tampa.

Assessment Of Nutrient Intake

Dietary intake was determined using the 24 h recall method by trained staff. All subjects were instructed to continue their ordinary diets before the dietary evaluation. The information gained on holidays or weekends was not excluded. Nutrient intake was calculated on the basis of the nutrient concentrations in foods using the Korean Food Composition Table, which was devised by the Korean National Rural Resources Development Institute . Fiber , ash , calcium , phosphorus , iron , sodium , potassium , -Carotene , retinol , thiamine , riboflavin , niacin , and Vitamin C were included in nutrient intake data. vitamin A /day) was calculated by summing retinol and -Carotene/6 . The individuals were divided into quartiles of total intake per day for each nutrient . If individuals had taken any kind of supplements consecutively more than 2 weeks over the past year or more than one time per week over the past month, they were regarded as taking supplements.

Results of the trial, led by Professor Jonathan Crowston and Dr Flora Hui at the Centre for Eye Research Australia, are published today in Clinical and Experimental Ophthalmology.

They show significant improvement in the visual function of glaucoma patients who received a daily high dose of 3 grams of nicotinamide for 12 weeks in addition to their regular treatment to reduce eye pressure.

Dr Flora Hui, from the Centre for Eye Research Australia, said a larger international trial was now needed to determine if the improvement shown in this study could be sustained over the longer term to reduce the progression of glaucoma.

The current study, which also includes researchers from the University of Melbourne, Duke NUS-Medical School, Singapore Eye Research Institute, Karolinska Institutet, University of Adelaide and Cambridge University, was conducted with glaucoma patients in Melbourne at private ophthalmic clinics and the Royal Victorian Eye and Ear Hospital.

For the first time, we have shown that daily high doses of vitamin B3 can lead to early and significant improvements in patients who are also receiving traditional treatments to lower eye pressure, Dr Hui said.

Summary:
In mice genetically predisposed to glaucoma, vitamin B3 added to drinking water is effective at preventing the disease. The vitamin administration was surprisingly effective, eliminating the vast majority of age-related molecular changes and providing a remarkably robust protection against glaucoma. It offers promise for developing inexpensive and safe treatments for glaucoma patients.

In mice genetically predisposed to glaucoma, vitamin B3 added to drinking water is effective at preventing the disease, a research team led by Jackson Laboratory Professor and Howard Hughes Medical Investigator Simon W.M. John reports in the journal Science.

The vitamin administration was surprisingly effective, eliminating the vast majority of age-related molecular changes and providing a remarkably robust protection against glaucoma. It offers promise for developing inexpensive and safe treatments for glaucoma patients.

“There’s an analogy with an old motorbike,” John says. “It runs just fine, but little things get less reliable with age. One day you stress it: you drive it up a steep hill or you go on really long journey and you get in trouble. It’s less reliable than a new bike and it’s going to fail with a higher frequency than that new bike.”

Vitamin B3 Supplementation Offers Significant Improvement In Glaucoma Patients: Study

Glaucoma is the leading cause of irreversible blindness worldwide, characterized by gradual dysfunction and loss of retinal ganglion cells and their axons which make up the optic nerve.

The disease has a range of risk factors, including age, genetics, and elevated intraocular pressure , yet clinically available treatment strategies target only IOPlowering, and do not directly address the neurodegenerative events at the level of the retina and optic nerve.

Vitamin B3, or nicotinamide, is a precursor of NAD+ and is a critical coenzyme found in every cell in the body, involved in hundreds of metabolic processes. Recent work has indicated that glaucoma patients are low in NAD+ serum.

While retinal ganglion cells endure significant metabolic stress in glaucoma but maintain capacity to recover function, and B3 supplementation provides robust protection of retinal ganglion cells in preclinical models. However, the potential of nicotinamide in human glaucoma is unknown.

To determine whether functional improvements observed with NAM supplementation in mice could be reproduced in humans with glaucoma in an interventional study, researchers from the Center for Eye Research Australia conducted interventional research.

A Humble Vitamin B3 Supplement Could Be The Key To Treating One Of The Biggest Causes Of Irreversible Vision Loss In The World

Researchers from the Centre for Eye Research Australia in Melbourne are conducting a world-first human trial of an over-the-counter vitamin supplement to treat glaucoma, a disease of the optic nerve which affects 60 million people worldwide.

Professor Jonathan Crowston is the lead investigator of the study and Dr Flora Hui is the Research Fellow conducting the six-month clinical trial. They hope to prove that therapeutic use of high dosage vitamin B3 could be used to support existing therapies for glaucoma, such as daily eye drops or in severe cases, surgery.

Imagine your cars engine is running a bit rough and as a result, the car doesnt drive smoothly. If you top up the engine with oil, the car runs better, even though you havent fixed the underlying problem, explains Dr Hui.

Our study hopes to confirm that vitamin B3 can protect nerve cells from dying, in a similar way that adding oil to a faulty car engine can still allow it to run more smoothly, she concludes.

Professor Jonathan Crowston leads the Glaucoma Research and is Managing Director of the Centre for Eye Research Australia. Glaucoma currently has no cure and vision loss is generally thought to be irreversible, he said.

How Far Along Is The Research

Many studies into vitamins and eye health have not yet reached the clinical trial stage of research, and even fewer have passed the stage of animal trials. Whats more, a lot of the current studies and their findings have come up with conflicting results. This does not necessarily mean that the research isnt correct, simply that the findings need more investigation to find conclusive evidence of the theories being put forward.

Glaucoma is a group of diseases characterized by optic nerve stress, often associated with elevated eye pressure. No one knows what causes optic nerve degeneration, and glaucoma can be a tricky disease to diagnose. It usually does not cause pain or other symptoms. An eye doctors goal in treating glaucoma is to detect the disease early and treat it promptly to prevent permanent eye damage.

How To Take It

Generally, high doses of niacin are used to control specific diseases. Such high doses must be prescribed by a doctor who will increase the amount of niacin slowly, over the course of 4 to 6 weeks. Take niacin with meals to avoid stomach irritation.

Daily recommendations for niacin in the diet of healthy individuals are:

Pediatric

  • Men, 19 years and older: 16 mg
  • Women, 19 years and older: 14 mg
  • Pregnant women: 18 mg
  • Breastfeeding women: 17 mg

What Can I Do Now

If you have a family history of glaucoma, early detection is still the best way to manage the disease, which is why regular eye tests are so important.

    In a first-of-its-kind clinical report, retina specialists at the New York Eye and Ear Infirmary of Mount Sinai have shown that severe vision loss from a self-prescribed high dose of over-the-counter niacin is linked to injury of a specific cell type in a patients eye. The experts report that discontinuing the vitamin led to reversal of the condition and have published their findings in the fall issue of Journal of VitreoRetinal Diseases.

    Niacin, also known as vitamin B3, is used for lowering hyperlipidemia or cholesterol and comes in prescription and over-the-counter forms. It can produce a rare toxic reaction called niacin-induced cystoid maculopathy, a form of retinal swelling.

    People often live by the philosophy that if a little bit is good, more should be better. This study shows how dangerous large doses of a commonly used over-the-counter medication can be, lead investigator Richard Rosen, MD, Chief of Retina Services at NYEE and the Mount Sinai Health System, said in a news release. People who depend on vision for their livelihood need to realize there could be long-lasting consequences from inadvertent overdosing on this vitamin.

    Generally, weight-loss supplements, nutritional supplements, and vitamins are used for general health and are not qualified HSA expenses. HSA owners usually cannot include the cost of diet food or beverages in medical expenses because these substitute for what is normally consumed to satisfy nutritional needs.

    Is There A Link

    Some research does suggest that there is a link between low levels of antioxidant vitamins and glaucoma. Yet, importantly, more research is needed to determine whether any of these types of antioxidants have a direct link to reducing the risk of glaucoma. Therefore, at the moment, there are no commercial vitamin products on the market proven to minimise glaucoma risk.
