Image Type

Perimetry knows a wide range of "Image Types": Grayscale, Defect value map, indices, cumulative curve..) In every visual field window (Series, Single, Trend..) you can switch between the image types by means of

The following list contains all image types. Whether an image type is enabled depends on the current window type and the examination data. Click on the image button for more information about that image type.


Button Hotkey Image Type Meaning
A General data general information about the examination like instrument, program, duration..
D Defect depth / Total deviation numerical defect values = deviation from age-corrected normal values
C Color Defect Map (CDM) color scale display of interpolated defect values
+ Color Defect Map PLUS CDM plus a superposition of the total deviation values as numerals
M Cumulative Defect Curve cumulative defect curve (Bebié curve)
+ Indices global indices (MD, PSD, LV..)
R Threshold / Raw data numerical values of the raw examination results
G Grayscale interpolated grayscale of the threshold values
P Probability map probability that a deviation from normal is NOT ACCIDENTAL
H Hill of vision (3-D) visual field as a 3-dimensional surface

TREND WINDOW
B Boxplot box plots on a time axis
P Percentile Plot graph of the percentiles versus time
S SuperTrend Color Defect Map, change numbers and significance symbol
D Change change of the defect values in the trend analysis as numerals
i Indizes Trend trend of the global indices
X Intellitext explains the results of the trend analysis in simple words
G GATT GATT = Graphical Analysis of Topographical Trends
+ GATT plus GATT with superimposed change values
N NATT NATT = Numerical Analysis of Topographical Trends
F FD-Plot Index FD versus time

LEFT-RIGHT WINDOW
Binocular Analysis the best value of both eyes
Congruence Analysis (homonym) Symmetry and differences between both eyes
Congruence Analysis (heteronym) Symmetry and differences between both eyes after mirror-imaging
