I need some way of measuring my nocturnal eye pressure

Submitted by Anonymous (not verified) on Wed, 05/05/2010 - 8:45am

measuring eye pressure while sleepingI need some way of measuring my nocturnal pressures. My daytime measurements are reasonably low most of the time, and relatively consistent. I want to start adjusting my medications (formulations, frequency, timing), but don't feel confident in doing this until I can take night time measurements.

I know this is a concern for just about everyone who has glaucoma. I'm surprised there isn't more discussion on FitEyes about how to take night time measurements, and how to interpret the data (I'm pretty sure I've read all that's there).

My evaluation Icare ONE tonometer arrived today. I will compare it to:

    * Icare TA01i
    * Reichert 7CR Tonometer
    * Pascal Dynamic Contour Tonometer
    * Ocular Response Analyzer
    * Reichert AT555 Tonometer
    * maybe another one or two tonometers...

Look for a full review in the near future on FitEyes.com. UPDATE: I have decided not to publish my review of the Icare ONE at this time. Please read Are handheld or portable tonometers appropriate for home eye pressure monitoring?

Let me offer an analogy. If I were reviewing golf clubs, I would not include a review of a baseball bat. A baseball bat is not appropriate for playing golf. During the process of evaluating the Icare ONE, I came to a broader conclusion about all handheld tonometer and their appropriateness for self-tonometry (home eye pressure monitoring). Therefore, I feel it is better to have that general discussion first. You can read my thoughts here: Are handheld or portable tonometers appropriate for home eye pressure monitoring?

There is a related discussion on the Icare ONE here: New iCare ONE Tonometer Designed for Home Eye Pressure Monitoring

For now, here are some pictures of my evaluation Icare ONE tonometer.

Just arriving via FedEx (below). Some tonometers it will be evaluated against are shown in the background.
