Quick Change in IOP

Submitted by Sally on Thu, 08/14/2008 - 7:55am

 I had an interesting experience last night while taking my IOP. My measurements were in the low 20's for the first 5 readings, (3 on the right and 2 on the left) before the total was averaged. Just as I was pressing the button to take the last reading for my left eye, my husband called to tell me there was an ambulance at his niece's house across the road. That reading was {30}. We could see that her child was being taken on the stretcher, but he was alert and looked good.

Saving Data

Submitted by Sally on Tue, 08/12/2008 - 10:53am

Can anyone explain to me how to save each IOP data collected for the day? I have had to save all the data at the end of the day because I have not been able to get the Serial Watcher program to add the newest data to that saved earlier in the day. It does not seem to work like Word, Excel or PowerPoint. Is there a way to save data each time it is collected, under the same file name?

brackets and asterisks

I want to be certain that I understand the AT555 readings when I take my pressures. I always do 3 readings per eye so the device can calculate the average. Then I use the average number as my IOP for that time. Sometimes, I get asterisks and brackets (fliers) so I continue testing that eye until I have 3 clean numbers. Then I use the average of those numbers.

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).

Daily data collection

I understand that the AT555 should be connected to the computer for data collection. I do not work out of my home, so I am away from home, at my office most of the day. What is recommended for data collection in a case like this? I do have a computer at work and at home, but it would be difficult to transport the tonometer to and from work every day, making the computer connections, etc. How do others handle situations like this?
