Stress raises intraocular pressure in rabbits

Submitted by dave on Fri, 05/22/2009 - 9:40pm

If you have been reading, you already know we have documented, through thousands of intraocular pressure measurements in real life situations, that stress can raise eye pressure in glaucoma patients. I just came across this abstract of an older study done in Japan that is of interest in this regard.

Purpose. To test whether encagement and volume load as stressors influence the intraocular pressure in rabbits.

Stress Negatively Changes Brain Structure, Serene Impulse Positively Changes It

Research has shown that stress can physically reshape the brain, causing both extensive and long-lasting damage to the human brain. Brain cells can shrink and the connections between neurons can decrease. In short, stress causes big changes to the human nervous system. In 2008, new knowledge regarding the effects of short-term stress were measured at University of California, Irvine, and breakthrough research on the effects of long-term, chronic stress were conducted at the University of Wisconsin, Milwaukee.

New Experiments With Inverted Yoga Postures and Eye Pressure

Submitted by dave on Sat, 09/20/2008 - 4:49pm

 I stopped doing all inverted yoga postures a couple years ago. The plow (plough, halasana) posture used to be one of my favorites. When I first started self-tonometry some years ago I did the plow posture for just a few minutes, then sat up and took some intraocular pressure measurements.

Excel Spreadsheets For IOP Data (Simple Version)

Attached is the simple spreadsheet format.

New self-tonometry members, please use either this spreadsheet format (simple) or the standard spreadsheet format (attached to the next message in this forum).

If you customize your spreadsheet, it is very important that you keep your data columns in the same order.

Please let me know if you have any questions. Thanks.

Excel Spreadsheets For IOP Data (Standard Version)

UPDATE: In 2010 we released FitEyes Insight software. There is no longer a need to enter your eye pressure data by hand in a spreadsheet. When you are using the FitEyes Insight software, your eye pressure data is automatically organized and stored in your own password-protected web page at

Beliefs And Intraocular Pressure

Submitted by dave on Mon, 08/04/2008 - 3:56pm

This post is part of a series of articles intended to help you understand the relationship between your thoughts and your intraocular pressure. When I speak about the relationship between stress and eye pressure, many of us have a hard time making the connection -- because stress is a constant in most of our lives. This exercise will help make the connection between IOP and stress clearer.

My Eye Pressure Scare

Submitted by dave on Tue, 07/29/2008 - 10:25am

This story has a positive end, but I did have a stressful situation yesterday in regards to my intraocular pressure. In the early afternoon I used the Tiolat iCare tonometer to measure my intraocular pressure, as I have been doing every day for a long time. I obtained seven intraocular pressure measurements (each the average of 6 probe contacts, so this was a total of 42 individual measurements) in the range of 3mmHg to 5mmHg in my left eye. (My right eye was a bit higher, in the range of 8 mmHg.)

The low intraocular pressure reading shocked me! Obviously, this is too low!
