Hard to say what the poster was looking for other than "more details".
The only place to get details on a study under way is from those doing
the study. What would participants know at this time? Participants
generally don't get any feedback on what they're doing until it's all
done. Bet most of them don't know what the IOP measurement is from the
Goldmann comparison until after the study is over. Maybe even the
Proview has the readings hidden so the patient or doc can't see what
they are? Most studies are double-blind placebo studies. Who knows
what the protocol is for the study without contacting the group doing
the study?
There's an abstract on a study done last year that can be read at
http://tinyurl.com/3zrlb One of the investigators for this study is
the principle investigator for the NYEE study.
"The Proview phosphene tonometer fails to measure ocular pressure
accurately in clinical practice.
Alvarez TL, Gollance SA, Thomas GA, Greene RJ, Marchetto PM, Moore EJ,
Realini T, Liebmann JM, Ritch R, Lama P, Fechtner RD."
Another study is in the Journal of Ophthalmology with different results
can be found at http://tinyurl.com/5oh6b
"Reproducibility of Self-Measured Intraocular Pressure With the
Phosphene Tonometer in Patients With Ocular Hypertension and Early to
Advanced Glaucoma.
Brigatti, Luca MD; Maguluri, Srigouri BS"
Quite frankly, I wouldn't waste the $$ unless my glaucoma specialist
really thought it was important to do home monitoring.

I tried the Proview on myself and found the results quite variable on
several trials within a five to ten minute period. I would never this
on my patients. It's a cheap piece of plastic with a spring
inside...not much different from an inexpensive ball point pen (which I
would find more useful).
Take care,
