the right way to measure IOP with Reichert 7

The Reichert 7 is really easy to use I must say but one still must be careful for proper alignment .  I found out how important it is to hold the chin close to the unit.  Away from the unit, you get a totally different reading.   I have to say though that  this is one of the smartest investments I ever made.  I even invited the girl dowstairs to come up for a reading.  She has a history of glaucoma in her family.  The last time she had her reading taken was a few months ago and it was around 19.  According to her she has some loss of vision but her doctor told her that it was not necessary to take any medications at this point.  It's heart breaking to see that many people are ignorant about glaucoma and let their future in the hand of one doctor..
