the truth about marijuana and glaucoma

there is a lot of focus in the u.s. and around the world on the potentially helpful aspects of using marijuana in medicine. much of the research is promising, although there are risks and unknowns when it comes to medical marijuana.

one specific area where there’s attention is on marijuana and glaucoma.

so, does marijuana help glaucoma? below is more information on this condition, and also specifics on marijuana and glaucoma and their potential relationship to one another.

what is glaucoma?

before looking at the particulars of marijuana and glaucoma and answering “does marijuana help glaucoma,” what is this condition?

glaucoma is a disease that affects the optic nerve and can ultimately lead to loss of vision and blindness. in most people, glaucoma affects both eyes, although some people may experience the condition being worse in one eye. there are two primary categories of glaucoma. the first is open-angle and the second is closed-angle.

with closed-angle glaucoma, the person will usually have relatively sudden pain and vision loss, but since there is a lot of pain with this type, the person usually gets medical treatment quickly so it can help prevent permanent damage.

with primary open-angle glaucoma, also often called chronic glaucoma, there is a slow progression, and many symptoms aren’t noticed including minimal vision loss. because of how slowly this progresses people often don’t get treatment for the condition until there’s already permanent damage.

one of the primary reasons people feel pain when they have glaucoma is because of the high levels of pressure in the eye.

the goal of most treatments for glaucoma is to improve how fluid flows from the eye, to reduce the production of fluid or a combination of both.

the first treatments usually given for glaucoma are eye drops, but they can have unpleasant side effects such as rarely retinal detachment or breathing problems. there are also surgery options if medicines don’t work and they can include surgery to unblock drainage canals, filtering surgery to open eye channels and drainage implants.

so, does marijuana help glaucoma?

marijuana and glaucoma

a lot of people wonder does marijuana help glaucoma?

medical marijuana has been linked to glaucoma for decades, and there were studies that showed that marijuana could help reduce the intraocular pressure people with glaucoma experience. with that being said, research showed that marijuana could only temporarily reduce the eye pressure of glaucoma. in fact, most research shows that with marijuana and glaucoma, the effects of the marijuana last only a few hours, and this is one of the biggest reasons marijuana might not be the best treatment for glaucoma.

glaucoma needs around-the-clock treatment, so it would require that someone use marijuana throughout the day to really get the benefits.

of course, with this comes the consideration that marijuana can alter your behavior and perception, and there are side effects that come with its use.

another reason a lot of researchers are rethinking the conventional wisdom about the relationship between marijuana and glaucoma is because there is some evidence coming to light that glaucoma may also be a neurological disease that comes from a reduced level of blood flow to the optic nerve. marijuana lowers blood pressure, which can result in even less blood flow to the optic nerve.

with marijuana and glaucoma, it’s not seen as an ideal treatment for early-stage patients.

however, even with that being said, with late-stage glaucoma, marijuana is often more encouraged as a treatment. the reason is because during late stage glaucoma the objective isn’t necessarily to treat it because the long-term damage has likely already been done. instead, marijuana may be used to help treat the accompanying symptoms and discomfort. for example, marijuana could help with the pain and nausea that can be associated with late-stage glaucoma.

there is likely to be continuing research on marijuana and glaucoma, because of the role cannabinoid receptors play in ocular tissue. it may be that in the future researchers are able to develop cannabis-based medicines that are more effective in helping with earlier stage glaucoma.

summing up—does marijuana help glaucoma?

so, does marijuana help glaucoma? as it stands right now, marijuana isn’t the preferred treatment for glaucoma, particularly when it’s in its early stages. first, with marijuana and glaucoma the effects are very short-lived, so they’re not very practical. also, there are risks and side effects that can come with the use of marijuana.

right now with marijuana and glaucoma doctors are more likely to recommend it when glaucoma has reached later stages, and the marijuana can be used as a way to help the patient cope with the side effects.

that doesn’t mean there isn’t a future for marijuana and glaucoma, especially as researchers are looking at cannabinoid-based medicines that could have positive future implications.

Contact Lenses & Presbyopia

Is your vision with your current contacts not as clear at all distances as it was before? Are you having difficulty reading smaller print or seeing in low light? Are you finding yourself holding objects further>>>>away to see them clearly? Have you enlarged the text on your digital devices?

Now with multifocal contact lenses for presbyopia, you may be able to stay in contact lenses longer, without compromising vision or comfort. The result is balanced vision near, far and in-between, across variable lighting conditions, along with remarkable comfort — even in challenging environments that can make your eyes feel tired and dry. Make an appointment today to see if multifocal contact lenses are right for you!

Digital Eye Strain

Computers, tablets, e-readers, smartphones and other electronic devices with visual displays all can cause tired eyes, digital eye strain, and computer vision syndrome.

Here are some tips that can help reduce digital eye strain:

Get a comprehensive eye exam.
Having a routine comprehensive eye exam is the most important thing you can do to prevent or treat computer vision problems. If you haven’t had an eye exam in over a year, schedule a visit with an eye doctor near you.

Use proper lighting.
Eye strain often is caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting. When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices. If possible, position your computer monitor or screen so windows are to the side, instead of in front or behind it.

Minimize glare.
Glare on walls and finished surfaces, as well as reflections on your computer screen also can cause computer eye strain. Consider installing an anti-glare screen on your monitor and, if possible, paint bright white walls a darker color with a matte finish. If you wear glasses, purchase lenses with anti-reflective (AR) coating. AR coating reduces glare by minimizing the amount of light reflecting off the front and back surfaces of your eyeglass lenses.

Adjust your computer display settings.
Adjusting the display settings of your computer can help reduce eye strain and fatigue. Generally, these adjustments are beneficial:

  • Brightness. Adjust the brightness of the display so it’s approximately the same as the brightness of your surrounding workstation. As a test, look at the white background of this Web page. If it looks like a light source, it’s too bright. If it seems dull and gray, it may be too dark.
  • Text size and contrast. Adjust the text size and contrast for comfort, especially when reading or composing long documents. Usually, black print on a white background is the best combination for comfort.
  • Color temperature. This is a technical term used to describe the spectrum of visible light emitted by a color display. Blue light is short-wavelength visible light that is associated with more eye strain than longer wavelength hues, such as orange and red. Reducing the color temperature of your display lowers the amount of blue light emitted by a color display for better long-term viewing comfort.

Blink more often.
Blinking is very important when working at a computer; blinking moistens your eyes to prevent dryness and irritation.

Exercise your eyes.
Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds. Some eye doctors call this the “20-20-20 rule.” Looking far away relaxes the focusing muscle inside the eye to reduce fatigue.

Take frequent breaks.
To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day.

Consider computer eyewear.
For the greatest comfort at your computer, you might benefit from having your eye care professional modify your eyeglasses prescription to create customized computer glasses. This is especially true if you normally wear contact lenses, which may become dry and uncomfortable during sustained computer work. Computer glasses also are a good choice if you wear bifocals or progressive lenses, because these lenses generally are not optimal for the distance to your computer screen.

What is dry eye?

What is dry eye?
Dry eye occurs when the eye does not produce tears properly, or when the tears are not of the correct consistency and evaporate too quickly.

In addition, inflammation of the surface of the eye may occur along with dry eye. If left untreated, this condition can lead to pain, ulcers, or scars on the cornea, and some loss of vision. However, permanent loss of vision from dry eye is uncommon.

Dry eye can make it more difficult to perform some activities, such as using a computer or reading for an extended period of time, and it can decrease tolerance for dry environments, such as the air inside an airplane.

What are the symptoms of dry eye?
Dry eye symptoms may include any of the following:

  • stinging or burning of the eye;
  • a sandy or gritty feeling as if something is in the eye;
  • episodes of excess tears following very dry eye periods;
  • a stringy discharge from the eye;
  • pain and redness of the eye;
  • episodes of blurred vision;
  • heavy eyelids;
  • inability to cry when emotionally stressed;
  • uncomfortable contact lenses;
  • decreased tolerance of reading, working on the computer, or any activity that requires sustained visual attention;
  • eye fatigue.

How is dry eye treated?
Depending on the causes of dry eye, your doctor may use various approaches to relieve the symptoms. Most common treatments are lubricating eye drops and healthy blinking techniques.

If you suffer from any symptoms of dry eye, it’s time to get some relief! Make an appointment today!
