Accurate home tonometers

Submitted by Anonymous (not verified) on Wed, 08/05/2009 - 6:52pm

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,

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, 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 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 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 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.

New tonometers designed for self-tonometry coming soon

Next month will see the introduction of an exciting new tonometer designed specifically for self-tonometry. I like what I have seen so far. After the product is released we plan to evaluate it and, of course, we will keep you informed via

How To Measure Your Eye Pressure At Home And Change the World Too!

I'd like to share my thoughts and experiences with you. I believe that monitoring my eye pressure closely has been invaluable for me. I also monitor a lot of other things, but intraocular pressure is still considered the most important risk factor in glaucoma. And I believe intraocular pressure is misunderstood. Therefore, we, the community of glaucoma patients, have two important opportunities in regard to monitoring our intraocular pressure right now. 

Best Tonometers For Home Use Self-Tonometry

In my experience the best tonometers for home use (a.k.a., self-tonometry) are the Reichert AT555 and the Tiolat iCare. Of these the Reichert is much easier to use.

Had  the proview: it never worked :(

I say that's no surprise! Thanks for reporting your experience.

miller13 also asked some questions about which tonometers are suitable for self-tonometry.

Developing a Tiny Wireless Sensor to Monitor Glaucoma Around the Clock

The original article is found on the Howard Hughes Medical Institute (HHMI) website. HHMI investigator Simon W. M. John shares our perspective on intraocular pressure monitoring. He recognizes that intraocular pressure can vary quite a lot even in one day and that the value of measuring intraocular pressure only twice a year, as is typically done in practice, is very limited.

Grateful for Dave and self-tonometry!

Hello Members,

I have had my Reichert AT555 for two days now and taken taken quite a number of readings. Though my IOP does fluctuate, which I did understand is expected, I have seen much lower pressures than I thought I would! My opthalmologist's target pressure for me was 25 on Xalatan. I had frequent pressures of 30+ in his office but much lower numbers in my optometrists office (my friend). During the past two days I have seen only 1 average of 32 in 1 eye, and the majority of the time the IOP is mid 20s or lower (this is off medication). I have been off the Xalatan for the past month. Of course, now that I see my IOP can be even lower than his target of 25, I plan to work on obtaining this on a consistant basis (off medications).

My Personal Self-Tonometry Setup

Submitted by dave on Sun, 06/01/2008 - 12:54pm

Someone recently asked me where I keep my tonometer. When I started self-tonometry, I kept my tonometer in my office in a convenient location so that I could check my intraocular pressure while working without getting up from my desk. I could check my IOP while talking on the phone or using the computer, for example. At that time stress was one of my main research focuses and work was my main source of stress. Eventually, I achieved excellent management of my intraocular pressure during the work day and I began looking at my diurnal IOP curve more closely.
