Pupilographical

Pupilographical (from lat. pupilla the pupil and the Greek. grapho - write) - method graphic registration of the width of the pupil. Pathological pupil dilation (mydriasis) or narrowing it (miosis), violation of direct or friendly reaction of pupils on light, on the accommodation and convergence are important in the diagnosis of many diseases, especially the Central nervous system. Measurement of the pupils with the help of pupillometry highly inaccurate. Method of objective pupillary photographic by, first proposed in 1885, L. Bellarmino for experiments on animals, was enhanced by LJ (O. Lowenstein)who cenotaphs of inhibition reaction of healthy and sick people. The disadvantage is the need to measure the compass width of the pupil at each frame and on the basis of these figures to draw the curve of the progress of the reaction of the pupil.
Proposed A. R. the Shakhnovich automatic cenotaphs movements of pupils by scanning gave the opportunity to get on the film expanded papillorama, to accurately determine the duration of the latent period of the light reactions (normal eye it is equal to 0,2-0,3"), just to record the course of the reactions of the pupil of the light, accommodation, convergence, and on all sorts of non-specific stimulation (sound, smell) (Fig. 1 and 2). Account of the reaction of pupils on the local lit limited area retina - method local pupillary - allows you to use pupillary for the study of the light sensitivity of different departments of the retina in case of its disorder.
