How to interpret the Structure-Function Report
Examination:
This section refers to the examination dates
and the time span between HRT and HEP
examination.
HRT RESULTS
Moorfields Regression Analysis (MRA):
Sectoral classification based on the relation of rim to disc area globally and
for each sector considering the age of the
patient according to Moorfields Regression Analysis. The ratio of the neuroretinal rim area is compared to the respective
normative database. Green checks indicate normal results, yellow exclamation
marks indicate borderline, and red X´s indicate outside normal limits. Please note
the temporal inferior and superior are
most sensitive for detecting early damage.
Test Information:
This section displays information about
the test time and date, the kind of stimulus,
stimulus size, test pattern, pupil diameter,
refraction and tools used during visual field
acquisition.
Patient Performance and Global Indices:
This section displays the total number of
False Positive and False Negative catch trials as well as Fixation Losses during the test.
The section of global indices summarizes
the VF status. Mean Deviation (MD) and Pattern Standard Deviation (PSD) as well as the
Glaucoma Hemifield Test (GHT) help the
clinician evaluating the visual field.
HEP RESULTS
Sensitivity, Total or Pattern Deviation:
The color-coded upper graph displays the
patients´ threshold values in decibel. The
lower graph can be chosen to show either
the grayscale, the probability maps of the
Total or Pattern Deviation.
The Structure-Function Map:
HRT and HEP results are conjointly displayed as a double ring system. Two rings are
projected on the reflectance image of the
ONH. The inner ring represents the structural measurement of the HRT, the outer ring
represents the visual field result of the HEP.
The color-coding of the two rings is consistent to the Moorfields Regression Analysis
(MRA) and follows the principle of traffic
signals. A green sector when “inside normal
limits”; a yellow sector when “borderline”;
and a red sector when “outside normal limits”.

Patient data:
This section displays general patient information as patient name, gender, date of
birth, patient ID and ethnic heritage.

Patient Data and Examination:
This section displays general patient information as patient name, gender, date of
birth, patient ID and ethnicity. Examination dates are given as well as the time span
between HRT and HEP examinations.
HRT RESULTS
Moorfields Regression Analysis (MRA):
Sectoral classification based on the relation of rim to disc area is given for each sector under consideration of the age of the
patient according to Moorfields Regression
Analysis. Measured values are compared
to the respective normative database.
Green checks indicate normal results, yellow exclamation marks indicate borderline, and red X´s indicate outside normal
limits. Temporal inferior and superior are
most sensitive for detecting early damage.
Table lists six most important stereometric
parameters as well as probability values.

HEP RESULTS.
Sensitivity, Total or Pattern Deviation:
The graph display may be chosen by the
operator and either show the grayscale, the
probability maps of the Total or Pattern Deviation.
Test Information, Patient Performance
and Global Indices :
This section displays information about
the kind of stimulus used, strategy and test
pattern. It also displays the total number of
False Positive and False Negative catch trials
as well as Fixation Losses during the test.
The section of global indices summarizes
the VF status. Mean Deviation (MD) and
Pattern Standard Deviation (PSD) as well as
the Glaucoma Hemifield Test (GHT) help
the clinician evaluating the visual field.
