[Problems and their solutions in today's perimetry].

Progress in the development of perimetry has been slow but certain since the first description of the perimeter by Goldmann in 1946. The creation of static perimetry, and of threshold detection with the multiple stimuli analyser of Friedmann, have been important stages in its development. Automatic perimetry (A.P.) is now available, our choice of apparatus being the Peritest, this instrument combining all the possibilities of A.P. with multiple or single manual perimetry in a very flexible manner. The apparatus allows 153 positions to be examined in the central 25 degrees and 55 in the periphery. The examination is conducted at a suprathreshold level (+ 0,6 log. U) after determination of the patient's eye threshold. Results are grouped in classes on a special chart to facilitate assessment. It is now possible, with the same instrument, to perform a detection A.P. (very useful in suspected glaucoma), a confirmative and limited manual study and, if necessary, a consecutive refined analysis.
