Glaucoma Treatment with Marijuana

Glaucoma treatment with medical marijuana is a popular topic for many patients with elevated intraocular pressure or IOP. Glaucoma is an eye disease in which the optic nerve becomes damaged over time, reducing peripheral vision. If not properly diagnosed and treated it can lead to blindness. The most common cause of the optic nerve damage in glaucoma is higher-than-normal pressure within the eye. Typically glaucoma treatment consists of lowering IOP with eye drops, laser treatment, oral medications and sometimes surgery depending on the type of glaucoma and how severe it is.

The idea that marijuana can be helpful in treating glaucoma dates to the 1970s. Studies conducted then showed that smoking marijuana lowered the IOP of people with glaucoma. As a result of this research, additional studies were conducted examining whether marijuana or its active ingredient, a compound known as THC, could be used to keep IOP lowered. This research was supported by the National Eye Institute, a division of the National Institutes of Health. The research found that when marijuana is smoked or when a form of its active ingredient is taken as a pill or by injection, it does lower IOP. However, it only lowers IOP for a short period of time-about three or four hours. This short period of time is a major drawback for the use of marijuana as a glaucoma treatment. Because glaucoma needs to be treated 24 hours a day, you would need to smoke marijuana six to eight times a day around the clock to receive the benefit of a consistently lowered IOP. Because of marijuana's mood-altering effect, smoking so much of it daily would leave you too impaired to drive, operate equipment or function at the peak of your mental ability.

The effect that marijuana has on your ability to function is not the only side effect from the drug, however. Marijuana cigarettes contain hundreds of compounds that damage the lungs. Research has shown that regular and frequent use of marijuana, particularly in high doses, can cause problems with short-term memory and concentration.

As scientists learn more about glaucoma, they have also come to understand that IOP is not the only factor that damages the optic nerve. Recent studies characterize glaucoma as a neurologic disease similar to Parkinson's or Alzheimer's. And, there is increasing evidence that reduced flow of blood to the optic nerve may also cause damage in patients with glaucoma. Unfortunately, marijuana not only lowers IOP, but it lowers blood pressure throughout the body. As a result, it has the potential to lower the blood flow to the optic nerve, effectively canceling out the benefit of a lowered IOP. So, while marijuana can temporarily lower your IOP, it's not recommended for treating glaucoma. Prescription medications, laser and surgical treatments have been tested and proven as effective treatments for the glaucoma.

Contact Lens Dry Eye & LASIK

Indiana LASIK Surgeon Scott Buck, M.D. cited some important information about contact lenses and dry eyes for contact lens wearers considering LASIK. “Dry eyes can be a very real problem for both rigid and soft contact lens wearers. Researchers reporting in the Eye & Contact Lens: Science & Clinical Practice demonstrated that both rigid and soft contact lenses negatively impacted the tear film surface quality. This research is important to keep in mind when contact lens wearers present for LASIK consultations since the evaluation of the tear film quality and quantity is a critical consideration of determining the patient’s candidacy for any type of Laser Vision Correction-but especially for LASIK surgery,” commented Dr. Buck. “Given that a significant number of our patients electing to have LASIK today are contact lens wearers, we need to be aware that some of the pre LASIK tear film abnormalities that we find are actually due to their contact lens wear and that with a sufficient amount of time without contact lens wear contact lens wearers who want LASIK will recover a normal tear film surface quality and be able to proceed with Laser Vision Correction,” noted Dr. Buck.

Contact lens patients considering LASIK or any type of Laser Eye Surgery for vision correction are encouraged to find the best LASIK Surgeons in their area and have a thorough evaluation, examination and consultation in order to find out if they are good candidates.

Indiana Seniors Have Better Vision

“Indiana seniors concerned with aging eyes will be pleased to know that overall-their aging eyes have better vision,” stated Ophthalmologist Scott Buck, M.D. of Northwest Indiana Eye & Laser Center in Valparaiso, IN. According to a recent study in Ophthalmology there has been a significant decrease is vision loss in older Americans. “The prevalence of activity-limiting visual impairment is decreasing and has been decreasing-and this is really great news for seniors. While the study wasn’t terribly specific, I believe that better cataract surgery and lens implants, better diabetes treatment and control and a sharp decrease in smoking all play a role in why seniors now have better overall chances of preserving their eye health and vision,” Dr. Buck stated.

Modern cataract surgery-with advanced technology lens implants has become routine and complications are pretty rare. Years ago, people waited until a cataract was so bad that even a poor surgical result was better than living with a cataract. Today, when the presence of a cataract impairs either the quality of vision or the quality of life, the techniques and procedures allow for safe and effective cataract surgery to be performed.

• Today, only 1 in 5 adults in the U.S. smoke cigarettes as compared to 1 in 3 in the 1980s.
• Smoking is a major risk factor for macular degeneration, which is one of the most common vision impairing eye diseases in seniors. 
• Diabetes is a leading cause of blindness and age and obesity are leading risk factors for diabetes.
• Even though diabetes rates in the U.S. continue to climb, better therapies are now available to prevent and treat diabetes-related eye health and vision problems.

To some extent, seniors have helped preserve eye health and vision by taking the step of having regular eye exams which are quite important for everyone as they age, especially people with diabetes and other health conditions that can lead to vision loss.

Cataract Surgery: When Can I Exercise?

Scott Buck, M.D., a Cataract Surgeon at Northwest Indiana Eye & Laser Center reviewed guidelines for resuming exercise after cataract surgery and lens implants. “My cataract surgery and lens implant procedure allows for a pretty quick practical and visual recovery,” stated Dr. Buck. “This is important to so many patients-especially as they want to be able to resume their daily activities and lifestyle quickly.”

Certainly exercise guidelines may vary slightly depending on your cataract surgeon and on the specific details of your cataract surgery, but in general within 24 to 48 hours you should be able to do light walking. Avoid any heavy lifting or bending from the waist to get objects from the floor until you get approval to do so from your cataract surgeon. Swimming and water activities should be avoided for at least the first week after surgery because getting water in your eyes could increase the risk for infection. However, most patients are completely back to their exercise routines within one month after surgery.

Driving after Cataract Surgery: Men vs. Women

Indiana Cataract Surgeon Scott Buck, M.D. remarked on cataracts and the impact of cataract surgery on driving safely, particularly with regard to differences between men and women. “An interesting study on cataract surgery and driving was reported in Clinical & Experimental Ophthalmology whereby motor vehicle accidents involving men decreased by 15.3% in the 12 months following cataract surgery but the frequency of postoperative crashes didn't change significantly for women,” noted Dr. Buck of Northwest Indiana Eye & Laser Center in Valparaiso, IN. “We know all too well that delaying cataract surgery often results in patients modifying their lifestyles and activities. This is especially the case as people restrict their driving in response to health and vision changes. We need to hear from patients about their driving habits and whether they have had to change them as their cataracts develop-then we can help,” said Dr. Buck.
