Dear Dr.Papp,
congratulating you on your study, I would like to ask you:
1) Did you use stereo or mono photographs; if stereo, were they simultaneously or sequentially taken ?
2) How much would the reproducibility be changed if instead of stereo photographs mono photographs were used ?
3) In view of the reproducibility of about 12% in measuring the neuroretinal rim area, how much must a change in rim area in progressive glaucoma be to detected as worsening of the situation ?
4) What was the experience of the examiners ? Were they still in the steeply ascending part of their learning curve ?
Kind regards
Jost Jonas
