I love how rational you are about the results of studies and that you make it clear what the limitations of a study are. A lot of people don't get the chance to participate in research or learn how to critically analyze the results of scientific research in their life, and your videos go through that thought proccess as well! Love your videos, keep on keeping on
I think the proper interpretation of the both studies is that if your gene is less protected against the glaucoma, then you better not drink coffee. If you are not sure if your genes are less protected against it, perhaps prudent not to drink coffee more than a cup a day. Nothing to loose from not drinking coffee.
I don’t drink coffee, I have once in a while, I could say, I could count on my fingers, through the years I didn’t drink coffee. Months has gone by before I will have a cup. I have had glacoma for years. I lost some sight on one eye, but I am restoring more sight on that eye!
I’ve had Uveitis now for 2 years, blurred vision, pressured eyes and floaters. Drs could not find out the cause. All my Bloods were fine and was also checked for a whole lot of other stuff. They wanted to put me on immune suppressants however I randomly thought it might be my coffee intake. I’m now 3 days in to no coffee and my Vision has started to clear! 😅
Very interesting. I have to comment on your excellent speaking voice. I can’t watch some videos because of hard to understand people. This video was well done and not over done. I had to like and subscribe.
One other contributing factor for the Northern European countries that may not be fully accounted for in the study are reduced sunlight exposure (lower Vit D, less NO generation from UV exposure, less red/infrared light exposure potentially leading to less modulation of inflammatory or other mitochondrial functions)
For me Coffee affect my eyes , no doubt whatsoever and so does Black tea and dark chocolate . if i drink 2 cups of coffee one in the morning one at noon then next day i wake up with dry itchy almost burning eyes , bags under my eyes and blurry vision for the first half hour... never fails... If i don't have caféine for several days that problem goes away . AND i love coffee Tea and dark chocolate ... One thing that helps A LITLLE is drinking a lot of water during the day BUT it does not help enough.... AND i don't like ANY herb teas and sugar drinks so just water... which SHOULD BE sufficient but missing the pleasure element so ,here goes boring living .... but not walking into walls is a significant incentive.
Since increase risk of Glaucoma (unless exfoliation glaucoma is different?) is linked to myopia, which is linked to lower exposure to outdoors and the sun. These are all colder climates that get much less sunlight during some parts of the year, which means that there's likely lower exposure to outdoors and sun. The increased coffee drinking and Glaucoma might be linked to the same environmental conditions.
Wind freezing temps and snowblind basically lots of brightness due to snow reflecting light are probably likelier sources of exfoliation glaucoma. It gets really cold wind n bright up here.

Very interesting. You explained it pretty clearly to someone that took biostatistics 50 years ago. Now I am slightly worried. Will I decrease my coffee? Will I fall asleep at work? 🤔
I can't stop drink coffee coz it gives me happiness and energy, but I will reduce drinking more. Thank you, Doctor, for the information you provide. May God grant you success
ruclips.net/video/2Ctz9gUGtuQ/видео.htmlsi=wQygVp81rAkQf6et&t=619 The answer is no. The study didn't find the same association with decaf coffe, tea or chocolate.
By simply having high BP, can increase IOP. I take mirtogenol ( European pine bark and bilberry), have not had high IOP in several years. I don’t believe coffee alone causes glaucoma. There are other factors such as virus. That’s another subject. Thanks for the informative video.
But actually, low blood pressure is more of a risk to vision loss from glaucoma because of the lower blood perfusion in the optic nerve. That's why it's probably not advisable to take some of the older glaucoma medication's that lower blood pressure.
It got a little confusing at the end because first you started talking about how coffee could be related to pseudoexfoliation glaucoma, but then you switched it to regular open angle glaucoma and IOP. Also it wasn't clear when you were talking about coffee raising homocystine whether that had to do with pseudoexfoliation or just circulation in the optic nerve and retina. One could take supplemental like vitamin B6, the preferably pyridoxal 5'-phosphate form, vitamin B12, and methylated folic acid to reduce homocystine. Maybe you should look at how drugs like Viagra and Cialis affect IOP; some studies from about 2010 and 2011 indicated the drugs increased or could increase IOP quite a bit, but I don't know if that's the case if one uses them regularly. I asked my glaucoma surgeon about it and he dismissed the concern and said you gotta live. Another point--pseudoexfoliation glaucoma is usually unilateral even though it's considered systemic. I don't know that anyone has an answer as to why that is. So someone may be quite resistant to primary open angle glaucoma but only develop glaucoma in one eye because of the quite high IOP from pseudoexfoliation glaucoma. Pseudoexfoliation glaucoma is also more difficult to control and more likely to lead to blindness. And there is equivocation about whether it has other health effects throughout the body, for example with the cardiovascular system and circulation. There really should be more research into pseudoexfoliation syndrome.
Hey Dr. Michael Really nice video. Btw I was wondering if i could help you edit your videos and also make highly engaging shorts out of them. Or whole RUclips management ?
Thanks so much for the informative video on coffee. In 2014 when I had a retinal detachment, my bio-molecular nutritionist told me that coffee was a de-mineralizer of the eye. He would agree with you on the issue being something in the coffee. I do drink coffee and limit how much and how often I drink a perfectly 'created' cup of joe. With that said, I do want to share my experience with coffee and eye floaters in this short: ruclips.net/user/shortsCrrnEreifpY Thanks again for the great content! ~ Steve
Hi, maybe the cause that PEX Syndrom in Serilanka is just 1% because ophthalmogists are rare and the most cases stay un diagnosierd also the map how much the countries drinks coffee is not accurate! in saudi Arabia they drink coffee like water :)
Pleasant voice . . . coffee and glaucoma. Correlational research is so hazardous. For example, the number of fire trucks at a fire is much higher at a serious fire. Do you suspect that the number of fire trucks --- higher at big fires -- are the danger? A clear and strong relationship! Maybe if you send fewer fire trucks, those big fires would cause less damage. Don't send fire trucks! Chua discusses the hazards of claiming causal relationships when only correlational data is present very well. People confuse it all the time. Wonderfully, he emphasizes at the end that type of glaucoma under discussion is not even the common type of glaucoma . . . not only there ongoing confusion between causal and correlational relationships, oftentimes, the actual variables in play are not even adequately defined.
I love your videos Doc. , but being alive is detrimental to your vision and health. The processes that keep you alive also kill you and cause your vision to fail. I'm not giving up everything I enjoy.

How to restore eyesight?
How are you restoring your eyesight?
I’ve had Uveitis now for 2 years, blurred vision, pressured eyes and floaters. Drs could not find out the cause. All my Bloods were fine and was also checked for a whole lot of other stuff. They wanted to put me on immune suppressants however I randomly thought it might be my coffee intake. I’m now 3 days in to no coffee and my Vision has started to clear! 😅

Thank you for explaining the science in an easy to understandable way for the layperson. I found your video to be excellent.

No family glaucoma that I know of but I have chronic dry eye had an eye test 2years ago
Wind freezing temps and snowblind basically lots of brightness due to snow reflecting light are probably likelier sources of exfoliation glaucoma. It gets really cold wind n bright up here.
Thank you! Very informative and thoughtful presentation.
ITS THE DONUT, not the coffee.
(sugar, and seed oils, both poison)
That’s if one is eating donuts 🍩!
Caffeine free coffee for me!

My question is this the same for every caffeine drinks like green tea and others or is it specifically for coffe only
The answer is in the video...

Wtf. It feels like im going blind. I'm drinking roughly 10 cups a day. I live in sweden.
These results indicate that most people need not be concerned.
Topnotch

Drinking no caf Teeccino herbal coffee as I watch this
Now what, is it coffee or not?
Sick, now I can get a weed card for my coffee habit ☕

You keep using excessive consumption as a metric, without quantifying it.
