Vision & Vitamins: No clear evidence Coenzyme Q10 helps eye health

eyelabeledCoenzyme Q10 (CoQ10) has become a popular supplement which is said to help with a number of health issues including cataract and macular degeneration in the eye, but the Mayo Clinic gives it a “C” grade for its benefits in the eye (meaning the evidence is unclear to support its use).  CoQ10 is also called Q10, Vitamin Q10, ubiquinone, and ubidecarenone.  It acts as an antioxidant in the body and has a role in producing ATP which is a molecule which provides energy to cells.  CoQ10 deficiency has not been reported in the general population and it is estimated that a varied diet will provide up to 25% of the measured plasma CoQ10 and that the body naturally makes the remainder.  Primary CoQ10 deficiency is a rare inherited disorder that causes neurologic and muscular dysfunction.

For healthy individuals there is not strong evidence to show that CoQ10 supplements improve athletic performance or prolong life.  There may be some specific circumstance where CoQ10 supplementation may be helpful.  There is some scientific evidence to show that it may be helpful in chronic heart failure and in the treatment of high blood pressure but more studies are needed.  CoQ10 has also been thought to be helpful in specific cancer patients who are undergoing chemotherapy.  There are not enough studies to show that CoQ10 is helpful for eye conditions such as macular degeneration.  According to some sources CoQ10 should not be used for diabetes, hepatitis C, or Huntington’s disease.

There have been some studies that use CoQ10 eye drops for some specific conditions affecting the retina, cornea, and optic nerve.  While early studies are promising for specific diseases, more studies are needed.  More commonly studies have used a tablet or capsule, injection, or intravenous (IV) CoQ10.   There are some side effects including insomnia, elevated liver enzymes, rash, heartburn, and fatigue that have been reported when using CoQ10.  As with all supplements be sure to check with your doctor or pharmacist before starting to take CoQ10 as it may interact with other medications (in particular blood thinners).

Foods that contain higher amounts of CoQ10 include beef, herring, chicken, soybean, canola oil, rainbow trout, roasted peanuts, sesame seeds, pistachio nuts, broccoli, cauliflower, orange, strawberries, and eggs.  A varied diet is helpful in providing a wide variety of nutrients and since CoQ10 appears to act in concert with other vitamins such as vitamin E, having a dietary source of this vitamin may help provide CoQ10 along with other nutrients and co-factors that will aid in absorption and in action.  CoQ10 naturally declines with age so maintaining a healthy diet is increasingly important.  Given the scientific evidence to date it seems unlikely that CoQ10 supplementation is helpful for vision in healthy people.

Vision & Vitamins: Can supplements prevent nearsightedness?

Nearsightedness (also called myopia) affects from 20% to 50% of North Americans and up to >80% of some populations in Asian countries.  The need for nearsighted correction with glasses or contacts can run in families and is more likely to be present if both parents are myopic.  The natural course of nearsightedness is that it can start in childhood or young adulthood and continue to progress up to age 20 or in higher corrections into the 30’s.

There are some conditions that may be associated with nearsightedness so regular eye examinations are recommended even if the prescription has stopped changing.  Nearsighted people and parents of nearsighted children are of course interested in finding ways to slow or prevent the progression of myopia.  There has been conflicting scientific evidence to support the relationship between reading and near work and higher myopia, however there was no proven association between nearsightedness and computer work.  There has also been some evidence to suggest that more time spent in natural light (outdoors) can help to reduce the increase in prescription over time.

There have been a number of studies to try and find a link between nutrition and nearsightedness and to this date there has not been anything proven to prevent natural progression of myopia in children and adults.

It is important for anyone affected by nearsightedness to have regular eye examinations with and optometrist or ophthalmologist even if the prescription isn’t changing.  Sudden shifts in the degree of nearsightedness can indicate conditions like diabetes or cataracts if changes are happening at an older age.

Correcting nearsightedness is usually involves using glasses or contact lenses.  Laser vision correction can be considered after the prescription has stabilized for at least 2 years.

LASIK Patients Very Pleased With Their Outcome

By | Cataracts, Laser vision correction, LASIK, PRK | No Comments

Recently, the American Society of Cataract and Refractive Surgery (ASCRS) reported that on average, 95.4 percent of LASIK patients are pleased with their improved vision.

This is worldwide, not just in the U.S. The ASCRS did a large study, looking at patient satisfaction in India, Iran, Turkey, South Africa, Spain, the Netherlands, Scotland, Ireland, France, and the U.K. If they had looked at Australia as well, they would have found more patient satisfaction.

About 16.4 million people have had a LASIK procedure, making it one of the most popular and successful eye procedures done. It was approved in 1995 by the FDA, and perhaps because vision problems are so quickly noticed by anyone who experiences them, and so disruptive of daily life, LASIK is also one of the most-often studied medical procedures. It is not surprising that so many innovations have been developed and improved in the 13 years it has been FDA-approved.

One of the requirements for a LASIK surgeon to have a good record of success with patient outcomes is thorough patient screening. LASIK is not a good option for everybody. Your eye doctor will examine your eyes very closely to determine your candidacy, and will also study your general health history. Performing LASIK on a poor candidate was done too often in the early LASIK years, and surgeons have paid close attention to what makes for a good candidate. If you are not well-suited to LASIK, you might be a good candidate for PRK, which gives results just as good.

Technology is continuing to advance and be refined, and if you are well-screened, have LASIK done by an experienced eye surgeon, and care for yourself afterwards according to your surgeon’s instructions, you can expect a very quick and dramatic improvement in your vision.
