New Study Links Caffeinated Coffee To Vision Loss

timothy posted more than 2 years ago | from the whiskey-linked-to-vision-blurriness-in-followup dept.

Medicine 203

dsinc writes "A new study suggests caffeinated coffee drinkers should limit their intake to reduce their chances of developing vision loss or blindness. According to a scientific paper in Investigative Ophthalmology & Visual Science, heavy caffeinated coffee consumption is associated with an increased risk of developing exfoliation glaucoma (abstract), the leading cause of secondary glaucoma worldwide. 'Scandinavian populations have the highest frequencies of exfoliation syndrome and glaucoma,' said author Jae Hee Kang, ScD, of Channing Division of Network Medicine at Brigham and Women's Hospital in Boston, Mass. 'Because Scandinavian populations also have the highest consumption of caffeinated coffee in the world, and our research group has previously found that greater caffeinated coffee intake was associated with increased risk of primary open-angle glaucoma, we conducted this study to evaluate whether the risk of exfoliation glaucoma or glaucoma suspect may be different by coffee consumption.'"

Personally I figure anything in moderation is probably less toxic than the world in general. If you enjoy coffee, drink a few cups a day and don't worry about it! Don't specifically drink coffee if you don't like it, and don't drink 15 cups a day..

The interesting thing is that we worry about these kind of slight threats to our health, but ignore the absolute real killers: sitting on our asses for most fo the day, not getting enough sleep, eating food that is barely food, stress...

Statistically Meaningless Conclusions (5, Informative)

Geoffrey.landis (926948) | more than 2 years ago | (#41549919)

Sorry, their conclusions are just not statistically justified.

Let me review what they found:
Compared total caffeine consumption of less than 125 mg/day to greater than 500 mg/day: no significant result
Compared abstain from caffeinated coffee to greater than 3 cups of caffeinated coffee daily: glaucoma relative risk in the interval 1.09 to 2.54
Compared consumption of (caffeinated soda, caffeinated tea, decaffeinated coffee or chocolate) to non-consumers of same: no significant result

That relative risk that they quote as being significant has a confidence interval with a lower end of 1.09; which is only barely above 1.0 (1.0= no effect). So, they studied one particular variety of one particular minor disease (of many health effects). Finding one effect at a trivial level is meaningless.

I think the key word is "suggest". I don't know how widespread glaucoma is, but if anyone I know has it I don't know that they do. The, I don't know how many people I know have high blood pressure, either.

I would think that anything that would increase blood pressure would be a risk for glaucoma. When they test occular pressure they tell you not to cross your legs, as that raises blood pressure and gives them a false, high reading.

If your blood pressure is high, you have a lot more dangerous things to worry about than glaucoma -- you'll probably die of a coronary long before you go blind.

However, this is a good excuse to smoke a joint while you're enjoying your coffee!

DiscountBorg(TM) (1262102) | more than 2 years ago | (#41549573)

This seems to be what a lot of research into drugs reveals--that one substance can affect two different people drastically, and sometimes it is genetic. I've read studies linking caffeine with protective cardiovascular effects in one group of people, and damaging cardiovascular effects in others. And there's also been studies linking increased caffeine consumption with reduced chance of cognitive decline and related illnesses later in life.

While we are at it: studies linking marijuana with protective effects in MS patients, compared to studies showing people with certain types of genes (a small percentage of the population) have an increased risk of psychosis after use. Or studies showing potential harm or positives from drinking alcohol.

My hypothesis: it's all a crapshoot, in the end, really.

Re:Correlation != Causation (2, Interesting)

Anonymous Coward | more than 2 years ago | (#41549801)

Must agree and disagree.

From our ignorant, "try banging the rocks together guys," state of science, yes, it feels like a crapshoot.

But these kinds of studies are great to have on hand, so that when DNA is well understood and cheaply examined we can find the factors that make caffeine good and bad for a person. The net result, in the Gattaca Age, will be that you go to the thrice repurposed GeneOMat drive through, get your print out and at the bottom just above your total_fitness_index, will be the list of drugs that work for you, and that don't.

Mine:

Caffiene: No benefits, no effects
Amoxycilin: Expect allergic reaction
Novacane: 10% expected effacacy
Cannabis: Expect contact nausea at exposure frequencies less than 1 per week
Rogane: Effective
Butenafine
      Hydrochloride: Ineffective
Alcohol: 1 std. serving per day, cardio_effects +, liver_effects negligble

At that point it won't be a crapshoot, and starting life knowing these things would be extremely useful.
The process starts with studies like this article.

"Outside temperatures, sun exposure and gender may trigger glaucoma"

Importantly, those with a lifetime residential history of living in the middle tier and south tier of the United States was associated with 47% and 75% reduced risks, respectively, compared with living in the northern tier...

Without having read the full paper, it seems to me that what they're saying is that your location has a lot to do with the risk. Perhaps it's the extra exposure to UV/Sunlight from snow reflection? So it makes sense that TFA finds an increase in risk for people in Scandinavian regions.

I thought the same thing. It seems far more likely it's genetic than coffee related. They are hardly the only population with a heavy coffee consumption. It would be more compelling if they found people in professions and such that drank a lot of coffee had the problem. I come out of entertainment and we drank it like fish and I don't recall many, if any in truth, with the problem. The French drink very strong coffee and a lot of it and they don't have a spike.

No, it means that you should stop reading dumb clinical articles taken out of context on Slashdot.

This is just one of those hundreds of thousands of medical articles trawling the data for a correlation so somebody can chase after another grant. According to TFA, they reviewed records of almost 79000 people and came up with 360 cases of this particular form of glaucoma. Then they take the self reported caffeine intake, adjust for 'other confounders' (waves hands) and come up with a weak (Relative Risk [wikipedia.org] 1.4) association that is barely statistically significant and likely not clinically significant at all.

Scandinavian people are more blue eyed than most ethnic groups and it's been known for years that blue eyed people may be more sensitive to vision problems caused by sunlight. It could also be that for some reason (ozone depletion?) that Scandinavia gets stronger sunlight than other regions. If they want to convince me that there is something to do this, show me a study in Brazil where there aren't very many blue eyed people and they drink a lot of coffee too.

Scandinavian countries are close to the Arctic circle, so they don't get night-time in Summer - just permanent twilight. The most critical hours for your eyes are between 10pm and 2am. Whenever you sleep, your eyes *need* pitch darkness to fully repair from the daily damage of sunlight, otherwise they will get tired and will raise the blood pressure of the arteries inside. Caffeine will do the same thing. If you start seeing blue spirals, they you are in deep trouble.

If it's not statistically significant, then how can we take this seriously?

Re:Not statistically significant? (1)

ColdWetDog (752185) | more than 2 years ago | (#41549817)

You're cherry picking a bit. The difference between (this specific form of) glaucoma rates between moderate (one cup) drinkers and less moderate (3+ cup drinkers) was not statistically significant. The difference between caffeine abstainers (those sad examples of humanity) and any caffeine addict was (barely) statistically significant.

However, all that says is that the the argument that "the association of caffeine intake and certain forms of glaucoma using this data set and these assumptions (the confounder regression)" is unlikely to be caused simply by chance. It says nothing else.

For that and a couple of other reasons, I would not go running out and switching to decaf.

Still, given that there were 120,000 data points in this study, and they don't seem to be correcting for multiple comparisons, I would think a P of 0.02 is pretty weak.

For 80k women, there were a total 360 cases (.45%).

The increase was higher for women in families who already had a history of glaucoma.

The link was specific to caffeinated coffee and wasn't found for other products (Tea, Chocolate, decaffeinated coffee)

There was a tiny statistically significant increase compared to abstainers.

I.e. take those 360 cases, and say there were 160 cases among abstainers and 200 cases among caffeinated coffee drinkers. So the actual increased number of cases due to drinking caffeinated coffee in the population of 80k women may have been something like .05%. This is a rough swag. The actual increase was:
"increased risk of EG/EGS (RR = 1.66; 95% CI, 1.09â"2.54; P trend = 0.02)"

So give up a lifetime of drinking coffee, the other benefits of drinking coffee in return for reducing your risk of Glaucoma very very slightly.

So, we need to avoid coffee to avoid going blind, or drink it regularly so that we don't get Alzheimer's?

Ok, I didn't read diddly squat, but I will go out on a limb and say that the researcher didn't speak to a common audience.

Researchers need to publish cliff-notes at a level that high-schoolers would understand. We all assume the study was "local" and flawed, but the "cliff-notes" would address that right up front!

Caffeinated coffee? That's just "Coffee" - add words if you've taken away the good stuff, not when it's au naturel.

It's all fatal. Some faster than others, I admit, but everyone eventually becomes infirm and dies and causality is pretty firm linked to existing in the world and doing things.

So, can we have good regulators to worry about stuff like Chromium in tap water and just start ignoring the really subtle stuff?

With the way Google has been spreading Chromium everywhere, I'll just avoid the tap water and stick with canned coffee.

coffee drinkers are more white-collar, sedentary types who read lot of documents either physical ones or on a LCD screen for the most part of the day... and at occasions, under poor lighting. Isn't this the cause of losing eye-sight ??

Personally, I consume reasonable amount of coffee daily basis and I am close to 30 now. So far I can manage reading without glasses. Since 2 years ago or so, I get very tired reading... somewhat an early sign of losing eye sight. Before that, for 10 years or so, I used to study + code... seems all these heavy duty work is paying the price.. not the coffee...

I dare you to say that at a foundry, you'll get chucked into a furnace and melted down.

Lowest of the blue collars drink far more coffee than any white collar type.

Coffee != Caffeine (1)

Theovon (109752) | more than 2 years ago | (#41550071)

A lot of people seem to associate coffee and caffeine, but all around the world, people get caffeine from other sources. Tea, chocolate, guarana, etc. Caffeine is not the only ingredient in these things that might affect you. For instance, the primary stimulant in cocoa is actually Theobromine.

One interesting example is a COFFEE ALLERGY. It doen't occur very often, but it does happen, and more often than with tea, for instance. Caffeine suppresses immune response (i.e. histamine production associated with an IgE reaction) to a limited degree and may therefore mask a mild allergy to other proteins found in the coffee. So you may not have any immediate allergy symptoms. But it does have an effect, and in the long term, it can lead to psychological disorders.

Doctors, can you please clarify this? Eating breakfast is becoming a terrifying experience. (Circle all that apply)

Coffee is good / bad for you.
Eggs are good / bad for you.
The healthier topping for my toast is butter(which has lots of saturated fat) / margarine(which is trans fat) .

I anticipate the stories of how whole wheat toast is secretly the cause of cancer.

If that's the case then half the people of Seattle should be walking with a cane. People there drink a LOT of coffee. I'd like to see a few more studies before I buy into this one.

WTF? Isn't that what is called 'Coffee'? Caffeine isn't artificially introduced into coffee. It's part of coffee.
