I have been taking massive doses of Vitamin C
recently. I have read several studies suggesting that
Vitamin C is very good for your eyes and for lowering
IOP.

Your eye has about 25 times higher concentrations
of vitamin C than your blood serum.

Can anyone post more studies or information?

I took high doses of Vitamin C a few years ago. I slowly built up to 12
grams/day. It did seem to reduce the IOP by about 2-3 mm, but there were a
few side effects such as occasional diarrhea (which is sometimes expected)

However, a bad side effect was that I developed a kidney stone which I was
fortunately able to pass without surgery. In my case, this was bad enough of
a side effect to make me stop taking it - I occasionally take up to 1 g/day
if I feel a cold coming on.

It is a fallacy that vitamin C causes kidney stones.

Apparently there is the argument that Vitamin C
can either acidify your urine or turn it alkaline.
Some people are susceptible to kidney stones
if their urine is either too acidic or alkaline.

But vitamin C can either be taken as ascorbic acid
or sodium ascorbate so this is not an issue.

I find it interesting that vitamin C lowered your
IOP. Does anyone else have similar experiences?

It is very disturbing that the stock of B & L went
up two points after news on their glaucoma
medication. It seems that corporate profits may
be leading to insufficient research into safer treatments
that dont involve huge corporate profits.
