Thank you SO much for this video! I'm studying to be an MT, and my ophthalmology unit is driving me nuts because I don't understand! Now I do. Thank you for helping me take better care of my doctors and patients! :)
thank you, the explanation was good. But i don't understand, with the tolo(?) pen Alison's pressure for the right eye was 19 and with none contact tonometer it was 14, the difference of 5 in a matter of minutes, how come? which instrument is more reliable? correct me if i'm wrong but it's said that if px pressures difference in 2 consecutive visit is about 5 then that could mean early glaucoma identification.
Let me tell you. Anything that has to do with touching the eye or taking contacts out. Skeeves me out. , that's a big no no in my book , the puff wasn't so bad (it made me flinch pretty bad though ha). But the other ones where they actually touch my eye ....... Your gonna have to tranquilize me ha. Cause there isn't a man strong enough to put those devices against my eyes ha
Video is a bit outdated - Why only 3 tonometers? Where is the new Non-corneal Diaton tonometer - tonometry over the Eyelid? ;) unlike all other corneal tonometers such as goldmann, tonopen or airpuff, Diaton allows to measure IOP over Eyelid and Sclera, without influence of corneal properties and without a need of drops.
i dont get this, im assuming that tests were performed in rapid succession, yet the pressure in the right eye is 19 with the tonopen, and 14 with the puff test.
does the eye pressure constantly change within a certain range of say, 10 to 20, all the time?
i hope that question makes sense, its been bothering me a bit
the puff test is not at all as accurate as contact tonometry such as with the tonopen. IOPs (pressures) will not change that quickly, though do fluctuate throughout the day. Its because of this difference that high pressures should ideally be confirmed with goldmann tonometry to make sure.
@ch12ag my opticians never do goldmann or tonopens, they just do the puff test. im in england though, we dont have a gold standard to compare to, so far as im aware.
14 times in one eye, and 3 in the other. thats how much i got blasted at my last checkup. christ, maybe i should get a tonopen and do it myself in the future XD
LOL sorry but 14 times!!! would have been easier to do goldmann lol but generally 3 measurements in each eye is sufficient with puffer. Which shows in its accuracy as only one is required with goldmann in each eye
I am an optometrist in england. The reason most do not do goldmann on every patient is because using the puff of air test its much quicker meaning you can spend longer doing other tests. If you find high pressures ideally you should then go on to confirm with goldmann. No No it doesnt constantly change you just have a small variation throughout the day but that is not what is happening here. Here all that is happening is that the tonopen reading is much more accurate than 'puff'
the tonopen actually touches the eye and applantes it rather than bouncing a puff of air off the surface. a puffer test will never be as accurate as an applanation principle tonometer like goldmann. the goldmann works on a fixed area which touches your cornea and by applying a certain amount of pressure and aligning images you vary and apply the right amount of pressure on the cornea to obtain a measurement, rather than measuring the time it takes for the puff to flatten the cornea
this is helpful

The AccuPen Handheld Tonometer is a nice, new portable unit.

@ch12ag oh i see, so if the non contact reading seems a bit high or low, it can then be validated by using a tonopen or goldmann test, right?

@monkeyskitz EXACTLY :) thats why in glaucoma Pxs ideally a GAT (goldmann reading is necessary before commencing treatment
