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?


Benefits I Am Getting From A New Earth

As you know from a couple recent posts on my blog, I have been recommending Eckhart Tolle's A New Earth webcast series with Oprah.

I recommended a particular episode to a friend. I want to share his reply and my follow up response.

Sleeping with Head Elevated to Reduce Eye Pressure

Welcome. If you are new to, please read about how to revolutionize your glaucoma management here.

Posture can have a profound effect on intraocular pressure for glaucoma patients. I have even found that lying down, which is something we all do almost every day, can elevate my intraocular pressure from normal to high levels.

Managing My Blood Pressure and Eye Pressure While Sleeping

In my first true 24-hour eye pressure monitoring period (back in 2007), where supine eye pressure measurements were taken, I found out that my eye pressure is much higher at night than expected. I also found out that my blood pressure is much lower. That's a bad combination of pressures for the health of the optic nerve.

First True 24 Hour Eye Pressure Monitoring

If you are continuing to experience deterioration of your optic nerve in spite of having low eye pressure (such as normal tension glaucoma - also called low tension glaucoma), you may find this information very interesting. In fact, I think all glaucoma patients who have any progressing optic nerve damage should have their eye pressure monitored during the night (ideally while they sleep at home in familiar surroundings).

A Lazy Day

I didn't sleep enough last night, and I felt a little dull today. Consequently, I just went through the motions in most of my activities today without pushing myself very hard -- and without putting much effort into the positive habits I've been developing, either. For example, I did not do any weight training today, nor did I  accomplish anything  extraordinary at work. I didn't get to cross off many items on my ToDo list.

A Middle-Of-The-Night IOP Exam

Submitted by dave on Wed, 11/01/2006 - 10:59pm

Today's IOP values include an interesting exam in the middle of the night (4:15 AM, which is the middle of the night for me). They also include data for 2:36 AM the following morning, when I was awake and working late. I have seen some indication that my IOP can reach the high twenties (or more) in my right eye when laying down or sleeping.
