Eye Pressure

Can we estimate our eye pressure with our finger?

Submitted by Anonymous (not verified) on Fri, 08/07/2009 - 10:37am

I am trying right now to get a feel of my pressure by just touchng the eyes with my index fingers. I can tell if it's high or low but I would like to become very accurate with the help of a tonometer. Which one do you recommend and what the difference in mg with for example a Goldman, Thanks.

Accurate home tonometers

I just found your blog -- it is quite interesting. I have pigmentary glaucoma diagnosed ten years ago.

Here is my second question: Are there any accurate HOME tonometers out there that don't cost a fortune?

Thank you,

Excitement raises eye pressure?

Submitted by dave on Sat, 07/11/2009 - 10:03pm

Question: I just had a really fun and exciting time and I measured my intraocular pressure afterwards (via self-tonometry). After this stimulating time, the intraocular pressure was average 25pts. It is usually only 16 this time of night.

Therefore, I think adrenalin plays a big part in my elevated eye pressures.

Does Licorice Increase Intraocular Pressure?

Does Licorice Increase Intraocular Pressure? I attempted to answer this question for a friend today.

Here is the information I have so far:

1. Glycyrrhizin is the main sweet tasting compound from liquorice root.

2. A derivative of glycyrrhizin is glycyrrhetinic acid.

3. Glycyrrhetinic acid inhibits 11β-HSD1 (11β-hydroxysteroid dehydrogenase type 1; 11βHSD1 is an NADPH-
dependent enzyme highly expressed in the liver and adipose tissue).

Lowering of intraocular pressure by wild carrot seed extract in rabbits

Submitted by dave on Fri, 06/19/2009 - 7:53am

In normotensive rabbits topical application of Daucus carota seed extract at the concentration of 0.3, 0.6 and 1.2% resulted in mean IOP reduction of 19.33. 23.20 and 25.61% respectively from baseline.

As no significant difference was observed between the change in IOP in 0.6 and 1.2% extract treated groups, 0.6% concentration was chosen for further evaluation in rabbits with experimentally elevated IOP.

Instructions for Sample Spreadsheets for Intraocular Pressure Records

There are two Excel spreadsheets available:

Both have the same column layout for the important data elements, and this is really the only important feature of any spreadsheet to me. The SimpleSample (Measurements tab) shows the key aspects.

Avisar R, Avisar E, Weinberger D: Effect of coffee consumption on IOP. Ann Pharmacother 2002;36:992-995.

BACKGROUND: Many ophthalmologists instruct patients with glaucoma to avoid coffee, although data supporting this practice are insufficient.

OBJECTIVE: To estimate the effect of drinking coffee on IOP.

The Comfort I Get From Monitoring My Eye Pressure

Submitted by dave on Sat, 05/30/2009 - 2:13pm

With the recent website upgrade to FitEyes.com, I decided to send an email to all registered member. While writing the email I was inspired to discuss more of my experiences with self-tonometry, the process of monitoring my own eye pressure. After I wrote and sent the email, I realized that we have a lot of visitors to FitEyes.com who are not registered and who would not be able to see the experiences and thoughts I shared with the registered members. Therefore, because I feel very passionate about the benefits of self-tonometry, I decided to post the entire email on my blog. Here it is (and now it is updated to reflect recent events such as my grandmother's most recent birthday).

Hi Everyone - I just upgraded the FitEyes.com website. It has been a long, long time since I have sent an email to all members. FitEyes has continued to grow and flourish in recent months. I want to take this opportunity to invite you to visit the new website and let me know what you think. Not only will you see a new design and new features, you will find lots of new content (some of it potentially controversial).

New Website Features

You will see that FitEyes.com has many new features. It is running on open source software now. (For you techies, the operating system is open source too: Ubuntu Linux.) You can form friendships and communicate privately with other FitEyes members. There are lots of other new features, so please explore and try them out.

Self-Monitoring Eye Pressure

It is my strong belief that almost every glaucoma patient or glaucoma suspect (or anyone with elevated intraocular pressure) will benefit greatly from self-tonometry. The practice of frequently monitoring your own eye pressure in your daily life will be universal in the future -- just as monitoring blood sugar is a normal part of managing diabetes today.
