INTRODUCTION
CAUTION : Federal laws restricts this device to the sale by or on the order of a physician.
Thank you for purchasing the TOPCON 3D OCT-1 Optical Coherence Tomography.
FEATURES
The user's manual is made so that the customer can refer to this manual when learning how
to operate the 3D OCT-1 software and when using it. This manual does not describe how to
take a picture and how to diagnose the photographed image. For the photographing method,
refer to the description about "Capture" in the instruction manual that is attached to each hardware.
This manual is provided for the following products.
Objective products:
3D OCT-1, OCT Viewer
This manual includes the description about the functions that cannot be used in the OCT
Viewer. These
functions are explained as shown below.
Example: (This function cannot be used in OCT Viewer.)
PURPOSE OF THIS MANUAL
This manual explains the details of the function and use method to make a good use of the 3D
OCT-1 analysis software. Before using the software, carefully read this manual to ensure that
you operate it efficiently and safely. Always keep this manual at hand to make a good use of it.

Displays for Safe Use
To encourage safe and proper use and to prevent harm to the operator and others or potential damage to
property, important messages are put on the instrument body and inserted in the User Manual.
We suggest that everyone understand the meaning of the following displays, icons and text before reading this user manual and observe all listed instructions.

The necessary capacity of memory and hard disk are changed depending
on the CPU in the personal computer or environment.
If the number of "Thread" in CPU is beyond 4, the processing may be
delayed. Reduce the number of "Thread" to use this software.
When the object to be displayed is changed, start this software again. 18
When entering the patient ID through the 3D OCT-1, a bar code reader, a
card reader, IMAGEnet, Multi-Viewer, etc., you must use only the alphabet,
numerals and "-". Moreover, the following symbols cannot be used for the
patient ID.
" \ / : 'Space' * ? . <> | _ ! # $ %
If you use a patient ID which does not meet the above conditions, the report
cannot be output correctly from time to time.
When the photography data is displayed, "Normative Date" is displayed
according to the patient's age at the photography date. However, it is limited
as mentioned below.
• When the patient is under 19, "Normative Data" for the age of 20 is displayed as reference.
• When the patient is over 81 years old, "Normative Data" for the age of 80
is displayed as reference.

When clicking the [Capture] button, sometimes the message "Ocular optical
information value exceeded the compensated limitation. Default value shall
apply." is displayed.
In this case, access "Data Management" again. Click the [Edit patient information]" button and then the [Ocular Param.] button to correct "Ocular
Parameters".
Sometimes the analysis function is not normally finished. In this case, the
thumbnail is marked with "Fail".
For "B-2: Filter", the data of the image being displayed are used and so you
cannot change the values of "Filter" directly.
The Measure Image function is based on the theoretical Gullstrand eye
model. If the parameters of the actual patient's eye, such as the diopter or
axial length, are different from the Gullstrand eye model, the measurement
results may be different from the length and size in reality. The clinician will
be solely responsible for the diagnoses and treatments based on the measurement results.
When modifying the data in optic disc analysis (refer to "4.2. Analyzing the
Optic Disc" (P.132), the circle center is calculated again.

When you have reanalyzed the data modified manually, the data modified
manually are erased and the "Disc" calculated automatically by the analysis
mode set in the "OCTSet Analysis" tab on P.219 is applied.
As the result of automatic positioning, the fundus image is sometimes
deformed to the oval shape on the fundus image display area (A-3). This is
the result of the positioning process and there is no problem.
After analysis, the images are automatically positioned. If sufficient data
required for overlapping are not provided, automatic positioning may not be
done correctly.
When you have changed to the original tomogram after changing to two or
more tomograms on the screen, you cannot return the edited layers to the
original status by "Undo Modify". After carrying out "Exit Modify", the edited
layers are decided and cannot be returned to the original status. However,
in both cases, the data are not saved. If you return to the patient list screen
without saving the data, you can start the operation from the beginning.
You cannot perform "Modify" for the image photographed by "OverSampling". When the "OverSampling" image is selected, the "Modify" function is
OFF. For the photography with "OverSampling", refer to the instruction
manual of the 3D OCT-2000 instrument body.

In the automatic optic disc analysis, sometimes errors occur due to the photographed condition as shown below. In this case, using the menu "Disc
Modify" displayed when selecting "Disc Segmentation", you can modify the
analysis result. Refer to "Disc Modify" on P.95 in addition to this page.
When RPE was not detected correctly (If the patients blinked, his/her fixation moved during scan, the tomogram overlaps the top edge of the image
area, or the image quality is low, this may occur), the analysis result may
not be correct.
The result of registration is as follows: Double-click an optional point on the
two tomogram display areas, the two fundus image display areas and the
upper right "Compare Window". The green line with a cross mark appears.
(Pin-point Registration™) Sometimes this green line with a cross mark
appears out of the 3D scan area (green frame).
There are two probable causes.
• On the two fundus image display areas, the fundus image is not aligned
with the "Overlay" image correctly.
• On "Compare Window", the two "Shadowgram" images are not aligned
with each other correctly.
138

To obtain the correct results, check the alignment on the two fundus image
display areas and on "Compare Window". If the images are not aligned correctly, carry out "Reposition" and repeat Step
The insufficient memory error may occur when selecting ten tomograms
depending on the environment.

After clicking [Run] in the "Register" menu, Thickness Map is not displayed
from time to time. In this case, click [On/Off] in the "Thickness" menu.
To display Thickness Map, the same layers in the selected image as those
in "Image 1" must be analyzed. If the different layer has been analyzed,
click the layer detection display selector buttons properly (refer to "A-2:
Image Processing Controls area" on P.83) and analyze the necessary layer.
Then, try the operation again to display Thickness Map.
Make sure that no other windows or images are blocking or placed over the
Volume window during the movie-saving/recording procedure.
When batch export of the data including "_" (underbar) is performed for the
patient ID which was created by the old version software, sometimes the
data cannot be output with the filename that was set through "OCTSet".
When the analysis has failed, it is probable that the instrument did not take
a picture correctly. It is possible that the analysis will be successful if the
instrument takes a picture again.
To prevent your software from being infected with a computer virus through
the network:
• Please prepare an antivirus software. Please use the antivirus software
applicable to your use environment.
• TOPCON has already checked this instrument's operation when Trend

Trimming Circle from 3D Data
• Compensation of circle diameter when trimming a circle from 3D data (The data when
photographing is used for the eyeball refraction data.)
If this compensation magnification exceeds the allowable range "0.8 - 1.2 times", the message "Ocular optical information value exceeded the compensated limitation. Default value
shall apply." is displayed. In this case, do not perform the compensation but proceed to the
next processing.
