Trabecular Meshwork Cell (detail) 
This is the winning image for North America -- IN Cell Image Competition. It shows the internal structure of a single trabecular meshwork cell. In this image, DNA has been stained blue, so the large clumps of blue just above centre are the cell's nucleus. Red lines are filaments of actin spread throughout the cell, while the green patches at their tips are the focal adhesions.
Optic nerve cells require vitamin C in order to function properly. Henrique von Gersdorff, Ph.D., a senior scientist at OHSU's Vollum Institute and a co-author of a new study showing how essential vitamin C is in retinal nerve cells had this to say:
We found that cells in the retina need to be 'bathed' in relatively high doses of vitamin C, inside and out, to function properly.
Hello fellow Glaucomians,
I was diagnosed this year on April 19 with Glaucoma, after visiting an eye clinic noticing that the vision in my left eye was a bit fuzzy. I had always had 20/20 vision - and still do (well, 20/25 now), but never was an eyeglass-wearer and, shamefully, my last visit to the eye doctor was circa 1997.
In a recent discussion on the FitEyes email discussion list we had an interesting exchange about allergies to the glaucoma eye drops. If you want to see how serious this can be, one picture is worth a lot of words:
On Fri, May 20, 2011 at 7:39 PM, a FitEyes member wrote to the discussion list:
For those of us with glaucoma or ocular hypertension, our goal is for the fluid in the eye (aqeous humor) to be able to flow freely out the two exit pathways from the eye. In this context, we had a recent discussion on the benefits of fish oil and DHA for glaucoma. In this discussion, someone raised this point:
Quote: "fish oil can improve membrane permeability"
That's a useful fact on its own. But that got me thinking about what I have learned from teaching and practicing Serene Impulse (and doing so as both a glaucoma patient and a personal self-tonometry researcher).
Fish oils (including DHA) may have a small effect on IOP -- but much less of an effect than other things I have identifed as a result of mixing self-tonometry and Serene Impulse -- and also as a result of interacting with other tonometer owners in the FitEyes community.
In pursuing knowledge that will help me manage glaucoma, I have a guiding principle: don't waste your time going after the small change. Go for the stuff with the big payoff. Mental and emotional tension, which always lead to tissue contraction, are a key area where we can find that big payoff. For some background, please see this link:

And here's another related post by Bailey:
And I will expand on all of this in the present article and tie it together into an (informal) theory of elevated intraocular pressure.
Here is a very interesting discussion which took place on the Fiteyes google newsgroup. The actual title was "glaucoma, emotions and stress as major factors for NTG."
Can you please explain or give some information on the damage rate of glaucoma over a span of time ?
For eg:- if today my loss is 70% and if i maintain my IOP below 20 or even below 15, how much time will it take for the damage to go to 75%.
i mean i want to know that if i control my IOP how long can i save my eyesight, just a general idea, exact figure not necessary.
Having had a very interesting conversation with another tonometer user today concerning questions related to the corneal and glaucoma, I decided to post this article I recently came across.
Here is the full pdf link..
I have been coming across a few articles and studies dealing with c-type natriuretic peptides (CNP) and opioid receptors as they potentially relate to glaucoma, IOP and neuroprotection. While I don't have enough to go on in order to build any cogent arguments, I will present what I have found as a matter of interest. As a quick preview, it seems that CNP has neuroprotective effects..
