Vitamin supplements may slow down the progression of glaucoma (B6, B9 and B12 & choline)

A vitamin supplement that improves metabolism in the eye appears to slow down damage to the optic nerve in glaucoma.

In glaucoma, the optic nerve is gradually damaged, leading to vision loss and, in the worst cases, blindness. High pressure in the eye drives the disease.

Glaucoma researchers have long theorized the substance homocysteine is somehow relevant to understanding the disease. Now, researchers have investigated the role of homocysteine in several ways.

In the current study, the researchers discovered that when rats with glaucoma were given elevated levels of homocysteine, their disease did not worsen.

The researchers also found that high levels of homocysteine in the blood of people with glaucoma did not correlate with how quickly the disease progressed, and that glaucoma was not more common in people with a genetic susceptibility to forming high levels of homocysteine. Based on these findings, the researchers concluded that homocysteine does not drive the disease but is a consequence of it.

Since homocysteine is a natural part of the body's metabolism, the researchers wanted to investigate metabolic pathways involving homocysteine in both rodents and humans with glaucoma.

They then saw several abnormalities, the most important of which were metabolic changes linked to the retina's ability to use certain vitamins. This change meant that metabolism was slowed down locally in the retina—and this played a role in the development of the disease.

In experiments on mice and rats with glaucoma, the researchers gave supplements of the B vitamins B6, B9 and B12, as well as choline. This had a positive effect. In mice that had slower-developing glaucoma, the damage to the optic nerve was completely halted. In rats, which had a more aggressive form of the disease with faster progression, the disease was slowed down.

In these experiments, eye pressure was left untreated.

By the way, I do believe you can get at least some of your eye ability back, but you really need to hit it from the pressure side, the blood flow side, and the nerve nutrient side.

Thanks for your advice, I am going to get that information. Sorry for my late replies, I’ve been in and out all day.
