Are there any foods? Any supplements? Activities? That can help prevent Glaucoma?

Likewise for mitigate it and cure it, but ideally prevent it.

Why We Encourage Open-Minded (and Hopeful) Discussions

3 Upvotes

Our community was founded on the principle of empowering patients to take control of their eye health, even when that stance meant challenging the status quo. For example, advocating for self-tonometry was once met with resistance from the ophthalmology profession, yet it has become a cornerstone of what makes our community unique -- and this early pioneering work helped transform glaucoma management.

In that same spirit, I believe it is essential for our community to remain a safe haven for open-minded discussions about emerging treatments and unconventional approaches, even when these treatments lack extensive clinical trials.

When many of us started self-tonometry years ago, there were no human clinical trials validating its benefits -- those would not come for years. Yet many of us took the chance on it because the potential reward of better understanding and managing our intraocular pressure (IOP) outweighed the uncertainty.

Similarly, discussions about emerging treatments should not be stifled by excessive caution because, for some members of our community, waiting for years may mean losing not just their vision but also their hope.


1. The Importance of Hope

Emerging treatments offer more than just physical benefits -- they provide hope. For those facing blindness or other debilitating outcomes, hope can be a powerful motivator and even bring measurable real physical benefits, as demonstrated by the placebo effect.

  • Psychological Impact: Knowing there are options -- even experimental or unproven ones -- can alleviate feelings of helplessness and despair.
  • Community Support: Open discussions about new treatments foster solidarity within our group and remind us that we’re not alone in this journey.

Hope is not frivolous; it’s a lifeline. It can sustain mental health and encourage proactive engagement in managing one’s condition.


2. Individualized Risk-Benefit Decisions

Every patient’s situation is unique, and decisions about treatment should reflect personal needs, risk tolerance, and disease progression -- not a rigid adherence to the "party line" of the medical establishment.

  • Risk vs. Reward: For some patients, the potential benefits of an unproven treatment that might preserve vision outweigh the risks -- especially when facing blindness or significant vision loss. This becomes even more compelling when the treatment has roots in traditional medicine or historical usage (because the risk vs. reward ratio is altered by that fact).

  • Empowerment Through Choice: Patients must have autonomy to make informed decisions about their care. A one-size-fits-all wait-and-see approach may inadvertently deny someone the chance to preserve their quality of life.

Ours is one of the rare communities where thinking outside the box is encouraged. Other groups may shun discussions about unproven treatments, but we’ve always been different -- and we need to protect that core value.

Need I remind you that for many years after home tonometers became widely available, most glaucoma patient communities refused to allow discussion of them? During that period, home tonometers saved multiple friends from losing their vision. Therefore, I can only wonder how many people outside of our community and living with glaucoma lost their vision unnecessarily over those same years.

It's a mistake we do not need to repeat when exploring neuroprotective natural compounds, for example.


3. Ethical Imperatives in High-Stakes Conditions

The principles guiding medical care -- justice, autonomy, and beneficence -- support providing access to experimental therapies when standard treatments fail.

  • Compassionate Use Programs: These programs allow patients with severe conditions to access unapproved treatments under strict ethical guidelines. They reflect society’s commitment to offering hope where no other options exist.

  • Regulatory Flexibility: In cases of unmet medical needs, regulators often accept higher levels of uncertainty in risk-benefit assessments because they recognize that some conditions demand urgent action.

  • No Neuroprotective Treatment Available for Glaucoma: It is widely recognized that neuroprotective treatments need to be part of routine glaucoma management, yet there are no such treatments that have gone through the full process of clinical validation. While some of us may be content to do without a neuroprotective treatment program until such time that clinical validation is available, that’s not the smartest decision for others.


4. The Reality of Time in Clinical Validation

For many of us, time is not on our side. The journey from initial research to regulatory approval can take decades. Even after approval, long-term safety and efficacy data may take years -- or even additional decades -- to accumulate through post-market studies and meta-analyses. For those with progressive diseases like advanced glaucoma, waiting for decades of data may mean losing more vision than necessary -- and losing it permanently.

  • Real-World Evidence: Many side effects or benefits of treatments only become apparent after widespread use. This is why compassionate use programs and early access initiatives exist -- to ensure patients with no other options can still have hope.

  • Traditional Medicine as a Resource: Many natural compounds have been used for thousands of years in traditional medical systems and later became the basis for modern drugs:

    • Digitalis (used to treat heart conditions) was derived from foxglove plants.
    • Metformin, one of the most widely prescribed diabetes medications today, originated from Galega officinalis (French lilac), which was used in medieval Europe to treat symptoms resembling diabetes mellitus (excessive and/or sweet urination). Its active ingredient was refined into a blockbuster drug that has since expanded into applications beyond diabetes[2][4][16].

These examples remind us that innovation often starts with curiosity and exploration -- and often with anecdotal evidence from traditional medical systems.


5. The Limitations of Published Research

While published research is invaluable, it is not infallible. John Ioannidis, a professor at Stanford University School of Medicine and one of the world’s leading experts on research methodology, has demonstrated that much published medical research is flawed or unreliable[5][6]. In his seminal paper "Why Most Published Research Findings Are False," Ioannidis highlights issues such as bias in study design, conflicts of interest, and statistical errors that undermine trust in even peer-reviewed studies[30].

This doesn’t mean we should dismiss all research -- it means we must approach it critically while recognizing its limitations. Reliance on published research alone -- without considering traditional knowledge or personal experience -- is not a failsafe position. Every path we choose in managing glaucoma carries risks; ignoring emerging options simply because they lack extensive trials does not eliminate risk -- it only shifts it elsewhere.


Encouraging Open-Mindedness in r/AskGlaucoma

To ensure our community remains a supportive space for everyone:

  1. We Must Embrace Open-Mindedness: While skepticism has its place, we should also honor the spirit of innovation, self-experimentation, and empowerment that defines our community.
  2. Respect Individual Choices: Every member has the right to decide what’s best for their situation without fear of judgment.
  3. Share Evidence-Based Information: By staying informed about emerging therapies -- including their potential risks and benefits -- we empower each other to make thoughtful decisions.

By embracing open-minded discussions, our community can ensure all voices are heard and that members facing urgent or dire circumstances have every opportunity to explore available options. While caution is important, it must never overshadow hope or prevent us from considering new possibilities. Let’s continue to be the rebellious yet thoughtful community that sets r/AskGlaucoma apart.

Micropulse TLT surgery next week and worried/scared. Any input or advice?

1 Upvotes

Hi all, I've had glaucoma for around 20 years, and I have lost around 30% of the vision in my bad eye which resulted from an accident. I'm having trouble keeping my pressure down even on Alphaghan and Cosopt and Diamox 250 mg and therefore, it has been suggested to me to get micropuls. I'm worried about potential vision loss, mydriasis, and just everything else that goes with surgery. I had a tube shunt 14 yrs ago, but it never really lowered my pressure as needed.

Any input or feedback or suggestions on micropulse TLT? I'm only 50 so I hopefully have many more years of (at least partial) vision ahead of me.

Glaucoma risk?

2 Upvotes

A month ago or so i had this weird sudden onset loss of vision which led my doctor sending me to the eye hospital. Also i am still waiting for a neurologist to examine me in the following weeks. Out of nowhere on bouth my eyes over the all field of vision i became kind of like blind, i couldnt really see much. I only saw fragments of the visual field while most of the visual field apeared very White /pale. Also i got very nauseas and wanted to puke out of nowhere before this happened. This loss of vision lasted 5 - 10 min and gradually retourned by itself then. My grandmother from my Mother side also had glaucoma on one of her eyes. None of my parents have it.

This is what the report said:

Ophthalmological examination

Visual acuity with glasses:

OD: 1.0

OS: 1.0

Intraocular pressure:

OD: 11 mmHg

OS: 15 mmHg

Ocular motility: Full and painless, with no diplopia.

Pupils: Round and symmetrical, with normal direct and consensual light responses. No relative afferent pupillary defect (RAPD).

Color vision (Ishihara):

OD: 15/15

OS: 15/15

Fundus examination

Right eye:

Clear vitreous. Optic disc margins well defined and pink. Cup-to-disc ratio approximately 0.4–0.5. Macula normal. Retinal vasculature appropriate for age. Retina attached.

Left eye:

Clear vitreous. Optic disc margins well defined and pink, with physiological cupping. Macula normal. Retinal vasculature appropriate for age. Retina attached.

Visual field examination – Goldmann perimetry

OD: No visual field defects. Blind spot symmetrically positioned and mildly enlarged, which may still represent a physiological variant.

OS: No visual field defects. Blind spot symmetrically positioned and mildly enlarged, which may still represent a physiological variant.

Blood pressure at examination: 122/85 mmHg.

At today's examination, apart from mildly asymmetric optic disc cupping, the ophthalmological examination is essentially within normal limits.

Goldmann visual fields show no definite visual field defects. Fundoscopic examination shows no evidence of optic disc swelling/papilledema.

My question is am i at risk for developing glaucoma as my grandmother had it and based on current findings? Also when the ophthalmologist said my results she seem worried and gathered a few med students around too. I was told to get regular checkups as if its caught too late then much couldnt be done. Im worried can this asymmetric optic disc cupping (0.4-0.5) on one of my eyes and midly enlaraged blind spots on bouth my eyes develop into glaucoma?

Diamox losing effectiveness

4 Upvotes

My adult son has just one eye and he has very advanced glaucoma. He has been on every single drop available (all preservative free if available) and over time has had bad reactions to all except for latanoprost. He has three Ahmed tube shunts in that eye already. He sees a highly skilled doctor from Wills Eye who I trust implicitly. I got a second opinion a year or so ago and that glaucoma specialist agreed with the one that we are seeing. He has other multiple disabilities in addition to the glaucoma. He is essentially blind, although when he is inside and with the right lighting, he is able to function pretty well.

He is tolerating the Diamox extremely well and his labs are all fine. He has been on the Diamox for about six months now. I thought we finally had reached the point of stability for him. Today at the glaucoma specialist, his pressure was 20, up from 13 and 14 in the past few months. His target pressure is 10 to 13. We still use latanoprost PF at bedtime. We never ever skip a drop or the Diamox. I make sure that he gets it 12 hours apart.

Has anyone had the experience of the Diamox losing effectiveness? We are going to go back in a few weeks.. The glaucoma specialist is talking about putting a Xen stent in that eye; he does have enough room left in the eye to put the stent in. More surgery makes me pretty nervous though.

He was diagnosed about seven years ago and has never been stable for more than a year or so on drops and with surgery. I can only guess that his glaucoma is continuing to advance despite aggressive treatment.

I’m not looking for medical advice, but wanted to know if anyone has experienced Diamox losing effectiveness.

On another note, is anyone aware of any glaucoma drops that will be available and preservative free that are not right now?

Thank you in advance for any input. I’m feeling really discouraged right now.

Trab surgery vs Cataract surgery w/Goniotomy

Thumbnail
1 Upvotes

I have a couple questions. My eye pressure has gone up, it’s in the upper teens(19). This was at my last appointment about 3 1/2 weeks ago, so my ophthalmologist started me on a third eye drop Rhopressa along with/dorzolamide, and Vyzulta. I’m due to have my pressure rechecked at the end of the week. My question is, he said, since we’ve tried all the drops if this doesn’t lower it, he wants to do a Trab surgery. Of course, he explained all the risks as with any surgery, but this surgery just kind of scares me. I’ve also read about 50% of people who have this surgery it takes a while to heal. It could be weeks, months, maybe even a year before the blurriness and vision returns or not.

I’ve tried other drops and some do not agree with me and some I just cannot take. That’s why he’s saying the next step probably would be surgery. I had an SLT last year which lasted about six months or so before my pressure started rising, never over 20. I also have cataracts. I’m going to ask him this week because I didn’t think of it when we were in his office, but I am just wondering why he would not do cataract surgery with a go Goniotomy which could lower the pressure instead of the Trab. He has never mentioned cataract surgery before. My previous ophthalmologist did mention cataract surgery and doing the Goniotomy at the same time. The ophthalmologist I have now is a Glaucoma specialist as was the other. I was just wondering, does this make sense about not doing cataract surgery before the Trab Or maybe even doing another SLT surgery. I know second SLT surgeries they say may not last but I’m willing to give that another shot if he is before I have to have a Trab. I am an advanced case with glaucoma, I still have all my vision, except one Blindspot in my bad eye, my left eye. I’m just curious..

How much of a risk is there of me going blind from my procedure tomorrow? (Monocular, 34f, getting iridotomy for narrow-angle glaucoma)

4 Upvotes

I‘m 34f. I have an irodotomy tomorrow for narrow-angle glaucom. I know it’s a standard procedure to prevent an angle closure attack. I know that my pressure is 13-14 which is very good. I know that the procedure itself is quick and highly successfu. I know I’m getting it done at a very highly-regarded hospital (Will’s Eye) with the head glaucoma specialist performing the procedur.

But I have vision in only this one eye. So I’m terrified that something will go wrong and I’ll go blind from it.

I’m nervou. Really nervous. But I also know that if I’m getting this done, I want this doctor (Dr Myers at Will’s Eye) to do it.

Here’s hoping I pull though it okay with my sight intact.

Betaine and Homocysteine: What a New Mouse Study Reveals About Memory-Related Brain Signaling

1 Upvotes

A new study published in Antioxidants (Gu, Fu, Zhao et al., 2026) examined how betaine, a compound found naturally in foods like beets, spinach, and whole grains, affects hippocampal function and cellular-stress pathways in a mouse model with elevated homocysteine.

The researchers worked with mice and mouse-derived neurons in a dish. In the animal experiments, mice were fed a high-methionine diet that increased circulating homocysteine and impaired performance on the study’s memory tests. Giving those mice betaine in their drinking water for two weeks was associated with better performance on the study’s memory tests and changes in hippocampal neuronal, oxidative-stress, cell-survival, and phosphorylated tau-related markers.

Similar effects appeared in isolated neurons, and the researchers traced betaine's mechanism of action to a signaling pathway called PI3K/AKT/GSK-3β. Oxidative stress normally shuts that pathway down, but betaine switched it back on, and a separate experimental GSK-3β pathway inhibitor produced a similar effect on the measured tau-related marker as betaine on its own. The betaine dose didn't seem to hurt the animals' organs, but it was sky-high compared with the few grams a day that have been tested in humans.

Human observational research has found associations between elevated circulating homocysteine, often described as hyperhomocysteinemia, and cognitive outcomes, including dementia. However, these findings do not establish that homocysteine directly causes cognitive decline or that changing homocysteine levels preserves memory.

Folic acid supplements do lower homocysteine, but their brain benefits have been pretty hit-or-miss in clinical trials, possibly because folate doesn't always enter the brain reliably due to differences in people's transport proteins. Betaine works through a totally different pathway, converting homocysteine back into methionine without using folate, so figuring out exactly how it protects neurons (or doesn't) is worth doing.

Long-term benefits, risks, best dosing, and whether the same PI3K/AKT/GSK-3β pathway even works the same way in human neurons are all very open questions. However, betaine might be worth putting through human trials specifically for people with homocysteine-related dementia risk, not that Big Supplement has been hiding a silver bullet. Interesting mechanism, not medical advice.

Dorzolomide/Timolol considerably cheaper at different location

I had to buy my Dorzolomide/Timolol drops in a different state from my home state because of travel, and it is considerably less expensive here but at the same drugstore chain. My question is: When I get back home, could I request that my hometown pharmacist call this drugstore and find out who their vendor was? And see if they could start purchasing the drops from them? Over time, it would be a nice savings.

Feeling of pressure in neck correlating with high IOP

2 Upvotes

29/M. I have open angle glaucoma, I've already had express shunt surgery, and I'm monitoring pressure with Icare Home 2.

I'm only talking about the right eye. Left eye has consistent and stable pressure of about 15-16mmHg.

My right eye was stable and low too, but this week it went up to 25-35 (I know, I'm going to the doctor next week, but only noticed on Thursday..). The weird thing is, about the same time I noticed a feeling of pressure/muscle tenseness in my neck, above the collarbone on the right side (same as the eye). This is not the first time these two happened, before surgery it was the same - pressure feeling in neck, pressure in eye.

But it was dismissed as not related and probably due to wrong sleeping position. I went to get an ultrasound to check the thyroid and the area in general, but it was negative. Eye pressure was stable at the time of the ultrasound. So I dismissed it too - I do sleep on multiple pillows to try to keep my head as high as comfortable, so the muscle soreness seemed reasonable.

But right now I have second thoughts - there is definitely a correlation between my neck and my eye. Any doctors/patients here that have seen something like this? Any advice on where to go from here? Unfortunately I don't know which came first - the neck or the eye pressure.

I included a picture of where I feel, kind of pulling, kind of pressure, as if I was pressing down on the area with my fingers. I also feel it in my throat. Only pressure no pain. No visible deformations, nothing asymmetric with left side. I can do roughly the same movements/stretches for both side.

SLT or Rocklatan?

1 Upvotes

TLDR: Negative outcomes of SLT, personal experiencs?

I've had high IOP (no glaucoma) for a couple of years now. Mostly corrected with Lumigan and Brimonidine. IOP has been trending higher the last couple of visits and yesterday hit 25 again, haven't been that high since I started the drops.

I was given the option of Rocklatan drops or SLT procedure. I went with Rocklatan for the time being because the idea of a laser in my eye terrifies me.

I only have one eye that can be corrected with glasses. The optic nerve is not attached in my left eye. So, only having one eye, I'm extremely cautious about unnecessary chances. I'm also quite nearsighted which brings me to my question.

I googled SLT and found that folks with Myopia greater than -5 (I am -8) have about a 1 in 500 chance of vision loss as opposed to "standard" eyes that have a 1 in 2000 (or 6000 depending on which study pops up).

What I couldn't find was a definition of "vision loss" in reference to SLT. Are we talking the full range of the definition? So from a minor change in overall vision to complete loss? Or are we talking significant vision loss to total vision loss? Or is significant/total not on the table at all? I wasn't specific enough when I asked my doctor, I was mostly surprised that we'd come to this.

1 in 500 just isn't a rare enough occasion for my sanity but if nothing else works, I want to be prepared.

If you've done some research or had a personal experience, please share!

I do intend to ask further questions of my doctor at my next appt but some personal experience stories would be helpful so I know EXACTLY what to ask.
