title: [Dynamic study of the optic papilla].
abstract: There are several methods of accurately measuring the contours of the papilla and rim. Of these methods, photogrammetry and its refinements are known to provide reproducible results. Unfortunately, there is a discrepancy between the accuracy of these methods and the biological "background noise". This noise does not allow the precision of these methods to be improved beyond a certain level. This also applies for determination of the color of the papilla. An alternative to this problem is to use the "provocation" test. In this article, we try to show the importance of the dynamic test of the papilla (dynamic provoked circulatory response): measuring the change in pallor of the rim during an artificial increase in the intraocular pressure.
