SAFETY CAUTIONS

CAUTIONS

Icon Prevention item Page

The necessary capacity of memory and hard disk are changed depending

on the CPU in the personal computer or environment.

10

If the number of "Thread" in CPU is beyond 4, the processing may be

delayed. Reduce the number of "Thread" to use this software.

10

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.

25

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 dis-

played as reference.

• When the patient is over 81 years old, "Normative Data" for the age of 80

is displayed as reference.

27

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 infor-

mation]" button and then the [Ocular Param.] button to correct "Ocular

Parameters".

28

Sometimes the analysis function is not normally finished. In this case, the

thumbnail is marked with "Fail".

62

For "B-2: Filter", the data of the image being displayed are used and so you

cannot change the values of "Filter" directly.

83

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 mea-

surement results.

90

When modifying the data in optic disc analysis (refer to "4.2. Analyzing the

Optic Disc" (P.132), the circle center is calculated again.

94

8

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.

96

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.

121

After analysis, the images are automatically positioned. If sufficient data

required for overlapping are not provided, automatic positioning may not be

done correctly.

121

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.

131

You cannot perform "Modify" for the image photographed by "OverSam-

pling". 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.

131

In the automatic optic disc analysis, sometimes errors occur due to the pho-

tographed 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.

138

When RPE was not detected correctly (If the patients blinked, his/her fixa-

tion 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.

162

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.

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 cor-

rectly, carry out "Reposition" and repeat Step

2 and 3.

171

The insufficient memory error may occur when selecting ten tomograms

depending on the environment.

175

Icon Prevention item Page

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.

175

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.

175

Make sure that no other windows or images are blocking or placed over the

Volume window during the movie-saving/recording procedure.

178

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".

181

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.

190

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

Micro Virus Buster Corporate Edition (Ver10.0 Service Pack 1) of Trend

Micro Incorporated is used.
