optic nerve death

Submitted by andrea on Mon, 05/12/2008 - 10:02am

When a part or even the entire optic nerve is dead, I know it does not promote vision. Does theis death grow like when a limb had gangrene? Is the Nerve 'dead' so it should be rejected by the body? I think it must mean something different from most tissue dead for optic nerves to be determined dead. Does anyone know or have a good hypothesis?


A New Earth Web Event

Tonight is the next webcast of Oprah Winfrey's online class with Echkart Tolle: A New Earth Web Event. I strongly suggest it is worth watching for all glaucoma patients and anyone else interested in maintaining good vision. There is more to the connection between this topic and our visual health than one might realize at first glance. The current chapters deal a lot with the ego.

My Inbox - Breathing and Eye Pressure

Submitted by dave on Sun, 08/05/2007 - 12:30pm

 Below is part of a very interesting email a reader sent me a little while ago. I asked for his permission to share some of it here. I hope this person eventually finds time to start a blog on or share more of his experiences. I could learn a lot from him, and I suspect many other people would like to hear more about his experiences with intraocular pressure.

Nasal Conditions Affect Eye Pressure

Submitted by dave on Mon, 02/05/2007 - 11:10am

Sinus conditions affect one's eye pressure. This is particularly important for glaucoma patients. Nasal blockage can have a strong effect on eye pressure and there are subtle effects as well. In addition, I speculate that the nose may offer an effective way for glaucoma patients to improve the long-term health of their optic nerve. The nose can be the doorway to the optic nerve as well as being intimately connected with eye pressure. In this blog post I'll touch on both areas.

Paradoxical Effects of Relaxation Techniques Elevating Eye Pressure

NOTE: This post was made in late 2006. The comments following it were made in early 2007. In the time that has passed since these initial intraocular pressure observations were made (see comments below), we have come to understand this situation much, much better. This thread is interesting for background information, but please see the more recent posts on if you want to really understand the relationship between stress, breathing, meditation and eye pressure. I have been in contact with a number of people who have tonometers and who have replicated some of these observations, and the patterns continue to hold. Basically, this seems to apply to all glaucoma patients. However, there are individual differences, especially among meditators and non-meditators.

This abstract simply triggers a discussion in the comments below. All the interesting info is in the comments.
