How to Prevent Macular Degeneration

Remember…peanuts aren’t nuts, they’re legumes

I saw an optometrist recently for a new eyeglass prescription and mentioned that age-related macular degeneration (ARMD or AMD) runs in my family. ARMD is the leading cause of adult blindness in the West. Thank God, I don’t have it….yet.

The optometrist suggested I start taking eye vitamins to help prevent ARMD. Popular eye vitamin preparations around here are Ocuvite and I-Caps. He said a multivitamin like Centrum might be just as effective.

UpToDate.com, a source I trust, says that supplements for prevention probably don’t work and are not recommended. Which means Centrum would be just as effective: i.e., none of them work.

Instead, UpToDate recommends regular exercise, not smoking, and relatively high consumption of leafy green vegetables, fruits, fish and nuts. Although they didn’t mention it by name, the traditional Mediterranean diet provides all of those.

On the other hand, if you already have macular degeneration (wet or dry), UpToDate recommends these supplements (probably based on the AREDS-2 study):

  • vitamin C 500 mg/day
  • vitamin E 400 mg/day
  • lutein 10 mg/day
  • zeaxanthin 1 mg/day
  • zinc 80 mg/day (as zinc oxide)
  • copper 2 mg/day (as cupric oxide)

An reasonable alternative for non-smokers and never-smokers is the standard AREDS formula. It’s the same as above except it substitutes beta carotene for lutein or zeaxanthin. You can buy both formulations over-the-counter in the U.S. pre-mixed so you don’t have to swallow a handful of pills, just one.

I was in a supermarket yesterday checking out eye vitamins and noted that Bausch and Lomb’s AREDS-2 formula costs about $10/month.

I haven’t decided yet whether I’ll take the optometrist’s supplement advice. Probably not. But I’ll go the diet, exercise, and non-smoking route.

Macular Degeneration Not As Scary As Before

…thanks to science-based research. Science-Based Medicine blog has the poop. A quote:

In my world of treating patients with retinal disease, a revolution has taken place over the past few years. The most aggressive form of macular degeneration has been transformed from a relentlessly progressive, disabling disease to one which can be tamed with medication. Now, patients diagnosed with exudative macular degeneration can expect stablization and even improvement in vision.

It is a story worthy of a Hollywood movie. Start with a reluctant hero; add controversy, Wall Street, politics, and most important of all, a happy ending.

The article is mostly about game-changing VEGF-binding drugs. VEGF = vascular endothelial growth factor. The one I’ve heard most about is Avastin.

Well worth a read if someone you know has age-related macular degeneration (ARMD).
