The method allows testing by means of the modusi: statically and kinetic fixation.
2.A.1. statical fixation
While working in regimen of statical fixation, the fixation point is situated in the center of the screen during the whole examining. It is presented as a black point surrounded by four angles. After fixing the patient's look, the red blot must land in the temple of the examined eye/should not be seen by the patient/. The programme, according to the adjustment, automatically sets the projection of the temple on the shield. If the anatomical position is not correct, the examiner manually fixes the red blot ion the right projection. When starting the examination, the red blot disappears and on its place in particular moments appear false stimuli. These stimuli cannot be seen by the patient while his look is fixed. Thus is used for control over the fixation. Another modus of keeping the fixation is the advent of a stimulus with maximum intensity in the center of the fixation point. It is used only to draw patient's attention and has no diagnostic value.
The study passes through two stages1) The stage of "rough" /screening/ testing the light-sensitivity of many single points in the central eye-field.
The number of points can be changed according to the duration and precision of the test / Programme adjustment/ the examination of every point is in this succession.
Is there patient's reaction at?
Every point of the central eye-field is tested in the sequence of this algorithm at the end of the 1.stage all the points that have not been seen with maximum intensity /absolute scotoms/ are tested again.
2) Stage of fine /exact/ testing of the eye-field.
The aim is there to be determined more accurate the size and the profundity of the faults , found during the first stage . It means that the most deeply are tested the points surrounding the eye-field part with changed light-sensitivity.2.?.2. Kinetic fixation
The algorithm of this version is quite similar to the static fixation's one. The test contains two stages and the second can be canceled.
The fixation point is white square. The special feature of this modus is that the fixation point moves from the center of the screen in any destination and at any distance The patient's look should follow the marker, so it guarantees his look's fixation at the moment of the test object's appearance. The position of the stimulus /test-object/ on the screen is refigured in connection with the position of the fixation point and the screen center. After the appearance of the stimulus and the reaction time, the fixation point returns to the screen's center.
In this method we use the abilities of the flickerkampimetry.
The algorithms of studying and analyzing of the results are quite cloze to the previous method's, so that the special feature and the main difference4s are in the way of presenting the test-objects. The modus of static kampimetry uses as test-objects fixed white points with different intensity. The test-object used for Flickerkampimetry is vibrating net.
The object's size is 1x1 cm, it's white changeable intensity and vibrating frequency 50Hz.
?his method also functions with static and kinetic fixation, and the study passes through the same two stages- "rough" and "fine" testing.

Applying the adjustment3 Black panel with circumferences
These circumferences are used to define the size of the eye-field. The size depends on the distance between the examined eye and the fixation point. To be correctly defined, ask the patient to fix the central point monocular. Afterwards drag the outer circumference, place it over the point and press the left button. Holding it move to left or right - the bigger point should get situated in the temple.4 The first slide
Moving the first slide, you can change the brightness of the background. In the left angle the brightness is presented in %.5 Second slide/precision/
It is used for adjusting the precision - better precision - more points to examine. The duration of the test is connected with the number of the tested points.6 The third slide
Use it to fix the reaction time of the patient after the appearance of the stimulus. When examine people older than 60 years, it is necessary the reaction time to be longer. The possibilities are: 1, 2 and 3 secondsThe test carry-out
