They also seem to be relying on DIY medical treatment even after apparently having this serious condition diagnosed by a professional.
The fact that the blog was created just to post this is somewhat understandable if the author really believes they're in the situation they're in. It definitely sounds like a desperate cry for help. I agree there is a lot of speculation in the post, but that's also understandable if the person is experiencing something scary. I hope they're wrong and it sounds like there's a decent chance they could be.
yeah very weird article
> At best it seems that I’ll likely never see a bright light or vibrant color ever again for the rest of my life, unless we get an aligned AGI that can fix me (<1%) or we start funding the NIH again and the scientists actually come back (0%).
I understand they are upset because of the symptoms involved but the lack of logic and knowledge here is something else. They mentioned they have used Kratom, which can apparently cause eye issues. Have they used anything else?
I do agree that vendors of genetically modified bacteria need some kind of plan or kill-switch for getting rid of their living therapeutics from your body.
If you are desperate then the Streptococcus mutans should respond to oral antibiotics penicillin, amoxicillin, erythromycin, and cephalosporins.

The author also started taking Lumina only 3 months ago, while supposedly it takes 1–2 years to colonize the mouth. Isn't that a very aggressive timeline for severe side effects?
Very unfortunate situation, but I'm doubtful that it's the bacteria causing it. As far as I can tell, it just doesn't produce enough formate. The body is pretty good at metabolizing formate, so it really only causes blindness from large, acute exposures, not smaller chronic exposure, AFAIK. Combine that with no other reports of blindness from other users of the Lumina probiotic, nor any similar issues appearing in rodent studies, and the bar for evidence is pretty high.
> nor any similar issues appearing in rodent studies
That's addressed in the OP:
> And in case you were wondering, this wouldn’t have shown up in the original BCS3-L1 rodent toxicity studies either as most non-primate animals metabolize formate much more efficiently, including rats. This has led to difficulties creating a rodent model of methanol toxicity, in fact.

I'm not certain they're correct there, as various studies seem to quote different numbers. Either way, I'm not sure rats are so much more efficient that it would matter: e.g. if the half-life in rats was a few tens of minutes vs the hour or so half-life in humans, would that make the difference between no toxicity and toxicity? Still, I haven't seen other people report vision loss, so maybe the point is moot anyway.
Although, it doesn't preclude some kind of uncommon impairment to formate metabolism, which would explain why it doesn't happen to other people.

I doubt an oral colony could produce enough formate to be an issue.
Methanol toxicity hits in the range of grams of methanol over a short period.
I have no idea how the bacteria are applied (oral rinse) but maybe enough got ingested to colonize the intestines? That could produce enough formate.

n=1 isn't necessarily data, and I have other questions (the formate concentration of the probiotic variant is 4x over JH1140, but JH1140 is itself a mutant; what's the formate production of an average wildtype strain?). Methanol can cause blindness in as little as 4mL, so the amounts we're talking about are relatively small; 4mL of methanol ≅ 99mmol.

Could be some sort of vitamin or mineral deficiency if I was to give you a positive angle, you really should check that as this >1% vs your other hypothesis. Check out nutritional optic neuropathy. Let us know
He did check that out. His test results ruled it out.
Stuff like this is pretty horrifying and sad after we are deregulating the FDA as we speak so this stuff will be harder to catch and also as we are killing all the science research to help fix this poor soul's eyes after the damage was done. Sad and horrifying.
Did the FDA ever regulate stuff like this?
It is marketed as a cosmetic to avoid clinical trials. However, the FDA has approved other dangerous drugs, like Vioxx. Notably, Lumina was brought to market in 2024, before any "cuts to science".

My wife’s a doctor, and she had patients begging her for leftover samples of Vioxx after it was pulled from the market. Lots of people with rheumatoid arthritis were willing to take the heart trouble risk in exchange for stopping the pain.
I don’t intend to argue we should kept Vioxx around, just to point out that the calculus can get complicated. I would vastly rather protect my heart than get rid of the insignificant amount of pain I experience. Turn that dial up far enough and people could rationally make the other choice.

Yes and no.
> Around that time, the patent they had for this bacterial strain expired. Aaron Silverbook, who founded a company called Lantern Bioworks, saw a way to rescue this technology from the regulatory red tape: what if it wasn’t filed as a drug but as a probiotic? He made a deal with Oragenics to acquire the recipe and aimed to get it approved by the FDA through its much less stringent probiotic pathway. He first sold it in Próspera, a libertarian charter city on a Central American island where any biotech product can be sold as long as the buyer signs a waiver, and now the product, renamed Lumina, is gaining hype on social media among cryptocurrency enthusiasts and DIY experimenters. You can even preorder the product for USD 250, to be shipped in June of this year.

I wonder how much variability there is in the product from batch-to-batch. Could one batch be producing unwanted by products at a much higher quantity than another batch?
It's a bacteria that's meant to colonize your mouth, the concern isn't byproducts in the initial dose, it's whether the bacteria after colonization produce harmful byproducts.
My guess would be that it's migrated to the gut or something
Wait, you're telling me I can get clean teeth AND free booze

>The Lumina Probiotic aka BCS3-L1 is a genetically modified strain of Streptococcus Mutans that was originally billed as producing ethanol and acetoin instead of lactic acid, outcompeting the wild type upon inoculation and thus dramatically reducing incidence of caries caused by acid buildup on the teeth.
i'm yet to see an alcoholic whose regular "mouth washing" by ethanol leads to good teeth (despite ethanol being very powerful antiseptic) .

The idea is that the wild-type Streptococcus that already lives in your mouth produces lactic acid, which is bad for your teeth. The modified bacteria produces ethanol instead, which is neutral for your teeth. I don't believe there's any assertion that the ethanol is helpful to your teeth, just that you're going to have some bacterial colony in your mouth, so they are trying to change the byproducts of that colony to something less bad.
According to the article as I understand it, the bacteria in question directly produces formate, the suspected culprit behind the vision loss. Ethanol being produced by the bacteria is not the relevant information here
my point is about selling proposition of that probiotic - production of ethanol which i'd not expect to be long term healthy on its own merits, even without formate.
Various metabolic processes in the body already produce methanol and ethanol. Now as to the relative quantities involved, I have no idea what can be produced by bacteria in the mouth.
Yeah, that is the big question here... how much is being produced. Also, how variable is the product from batch to batch? Could one batch be producing byproducts at much higher quantities than another batch?

The article is also from a blog that was only created 2 hours ago, and has this one post.
I'm not sure why this is all the way up the front page, but it seems very unwarranted.
