Scan position adjustment range (blue) Displays the "6.0mm×6.0mm" range at the focal point on fundus. Touch this range, and the scan position is moved to the touched point. For the "Cross" and "Radial" scan patterns, the intersection (center of the displayed scan pattern) of lines is the limit of the movable range. For other scan patterns, the edge position of lines is the limit of the movable range. In the case of the tomogram within the "6.0mm×6.0mm" range, you can get the output sensitivity enough. Scan possible range (red) Displayed only for "Cross" and "Radial" scan patterns. This range shows the "12.0mm× 12.0mm" range on fundus. This is the limit range where you can get a tomogram by using this instrument. If a tomogram exceeds the "6.0mm×6.0mm" range indicated by the blue line, you cannot always get the sufficient output sensitivity because the pupil and others obstruct the photography. Fine adjustment buttons (up/down/right/left) Each time you touch these buttons, the scan position is moved by about 0.03mm (on fundus) in the arrow direction. Reset button Displayed only for others except "Circle" scan. Returns the scan position to the center of the scan position adjustment range (blue). Rotation buttons (clockwise/counterclockwise) Displayed only for "Line" scan. Each time you touch these buttons, the scan line is rotated by 5° in the arrow direction. OK button Displayed only in "Circle" scan of glaucoma mode. Press this button after adjusting the scan position to exit from the scan position adjustment mode. * The circle scan position after adjusting (the circle scan position before pressing the [OK] button) is stored while you are taking pictures with the same patient ID. If you take a picture with other patient ID or exit from the photography mode ([Capture Data] mode), the stored circle scan position is automatically cleared and the scan position is reset to the default.

* When you want to return the scan position to the original position after adjusting it, do not press the [OK] button but press one of the scan pattern icons, which are displayed in Area 3 of the monitor screen, to exit from the scan position adjustment mode. If you have already exited from the scan position adjustment mode by pressing the [OK] button, you need to perform any of the following procedures: • You should shift to the photography with the other patient ID or exit from the photography mode ([Capture Data] mode) and return the scan position to the default. • You should access the scan position adjustment mode again and readjust the scan position to the desired one. Optic disc auto search effective range (red) Displayed only when the optic disc auto search function is ON in "Circle" scan of glaucoma mode. This indicates the "4.0mm×4.0mm" range at the focal point on fundus. Use this range to adjust the "Circle" scan position manually to the optic disc center. To put the patient's optic disc into this range, move the fixation position (move the optic disc) by the internal fixation target position move switch on the control panel. Then, adjust the circle scan position so that the circle center may be aligned with the optic disc center. By adjusting the "Circle" scan position to put the optic disc into this range, the optic disc is automatically detected by the optic disc auto search function thereafter. Optic disc auto search button This button can be set to ON/OFF only in "Circle" scan of glaucoma mode. When this button is set to ON, the optic disc position is automatically tracked and detected. Even if the optic disc moves slightly due to the minute fixation move, you can always perform "Circle scan" with the optic disc as the center. Sometimes the optic disc cannot be automatically detected due to the optic disc shape of the patient or the image contrast. In this case, follow the countermeasure (search OFF or manual set), which is displayed with the error message, and perform photography again. For details of the countermeasure (search OFF or manual set), refer to "MEMO" on page 65.

: Displays the "Image Quality" level with a value. * In the scan mode for the anterior segment photography, the Image Quality value is not displayed.
Image Quality value (IQF) is the image quality evaluation standard peculiar to TOPCON. IQF shows the image quality of the tomograms obtained by 3D OCT-2000 with a value quantitatively. When you need a tomogram applicable to image analysis or other processing, IQF must be 45 or higher. If IQF is 45 or higher, the tomogram has a proper image quality. If IQF is 70 or higher, the tomogram has an excellent image quality. If IQF is less than 45, image analysis can be performed for the tomogram but the reliability on the analysis result is reduced. So the tomogram is not applicable for analysis. • [Image Quality] level meter
: Displays the "Image Quality" level with meter. * In the scan mode for the anterior segment photography, the [Image Quality] level meter is not displayed.
• Live image
: Displays the live tomogram image. In the scan mode for the macula photography and glaucoma, the live image is displayed in color. In the scan mode for the anterior segment photography, it can be displayed not in color but also monochrome. "Monochrome display" is initially set.
• [Optimize] button : Starts "Auto Z", "Auto Z Lock" and "Auto Polarization" and detects the retina position automatically. Then, this button optimizes the image output sensitivity to display a clear tomogram. * In the scan mode of the anterior segment photography, all the auto functions are invalidated and so the [Optimize] button is not displayed. • Warning line : This is displayed when part of the tomogram overlaps the top edge of the tomogram live image area. If you take a picture in the condition that this (orange) for the tomogram display line (orange) is displayed, analysis after photographing may not be successful. Therefore, lower the Z lock position until this line disappears. position Then, take a picture. * In the scan mode of the anterior segment photography, if the tomogram is displayed within the optimal display position frame and then you take a picture, analysis is successful. So, the warning line (orange) is not displayed.

Scan setting Scan setting item buttons (1) Scan Pattern Scan pattern means the shape or kind to be scanned. It is classified into the following seven kinds. However, in the scan mode for the anterior segment photography, only three scan patterns, "Line", "3D" and "Radial" can be used. Line: Scans linearly. Circle: Scans circumferentially. 3D: You can scan the set range (Scan Size) with the set resolution (Scan Resolution) and display the scanned object as a stereograph. Radial: Scans radially with the set radial lines (Radial Scan Count). Cross: Scans in a horizontal or vertical cross shape. 7Line Raster: Scans horizontally with seven lines at regular intervals (Raster Scan Step). 7Line Raster (V): Scans vertically with seven lines at regular intervals (Raster Scan Step).

(2) Scan Size "Scan Size" means the length or range to scan. The selectable scan size is changed according to the scan pattern. For details, refer to "Setting the scan protocol" on page 48. (3) Scan Resolution "Scan Resolution" means the data quantity to be read by scanning. In the "Line", "Radial", "Cross", "7Line Raster" and "7Line Raster (V)" scan, it is the data for one line. In the "Circle" scan, it is the data for one circumference. In the "3D" scan, it is the data for each side of "Length×Breadth". As the scan resolution is higher, a more detailed tomogram can be obtained and at the same time the data quantity is increased. So, it takes a longer time to process the read data and the saved data are increased. The selectable scan resolution is changed according to the scan pattern and scan size. For details, refer to "Setting the scan protocol" on page 48. (4) Over Scan Count "Over Scan Count" means the following function: The data are read several times at one position for one scanned line. Two or more tomograms at one position are obtained and are displayed in the overlapped status. Consequently the tomogram with better contrast than usual can be obtained. At "Over Scan Count" on the screen, set the count of the overlapped tomograms. The selectable overlap count is changed according to the scan pattern and scan resolution. For the "3D" scan pattern, overlap cannot be done. For other scan patterns, when the scan resolution is set to a higher value except "1024", overlap cannot be done. For details, refer to "Setting the scan protocol" on page 48. In the initial setting of this instrument, "Over Scan Count" is set to "4" for all the scan patterns except "3D" for which overlap cannot be done, "7Line Raster" (scan resolution: 4096), "Radial" and "Circle". (5) Reference Position You can select one of the following items according to the scan mode to be set. Macula1 - 3 and Glaucoma1 - 3 There are two selectable items, "Vitreous" and "Choroidal". When you set "Vitreous", you can obtain a tomogram with the reduced noise at the vitreous body side from the retinal epithelium. When you set "Choroidal", you can obtain a tomogram with the reduced noise at the choroid side which is inner from retina. To obtain a clear tomogram at the epithelium such as retina, you should set to "Vitreous". To obtain a clear tomogram at the inner place from retina (e.g. choroid or optic disc), you should set to "Choroidal". In the initial setting of this instrument, "Vitreous" is set.
Selectable reference mirror position
43 PREPARATIONS
Anterior Seg.1 - 3: Only for the "Line" scan patterns, you can select one of "Cornea" and "Lens" (crystalline lens). For the "3D" and "Radial" scan patterns, "Lens" is not usable and "Cornea" is fixed. In the initial setting of this instrument, "Lens" is set. "Cornea" is applicable to take a tomogram of the tissues behind cornea. "Lens" is applicable to take a tomogram of the tissues behind the crystalline lens. To take a picture of cornea and crystalline lens, you should set to "Cornea". To take a picture of anterior chamber angle, you should set to "Lens". By setting so, you can obtain a clear tomogram. (6) Radial Scan Count This is valid only when "Radial" is selected as the scan pattern, and it means the count of the radial lines for scan. In principle, one of "6" and "12" can be set. In the initial setting of this instrument, "12" is set. In the scan mode for the anterior segment photography, "6" is not usable and "12" is set.
Selectable radial scan count
(7) Raster Scan Step This is valid only when one of "7Line Raster" and "7Line Raster (V)" is selected as the scan pattern, and it means the interval of the vertical or horizontal seven scan lines. The settable range is 0.15mm to 0.35mm, and you can set it by 0.05mm. In the initial setting of this instrument, "0.35mm" is set.
Selectable raster scan count
44 PREPARATIONS
(8) Fixation Position Set the fixation position of the patient in the scan mode for others except the anterior segment photography. In the anterior segment photography mode, only the external fixation target is used and so this item is not displayed. There are three selectable items, "Disc", "Center" and "Macula". When "Disc" is set, the optic disc is positioned at the center of the photography screen for the fixation position. When "Center" is set, the middle position between the optic disc and macula is positioned at the center, and when "macula" is set, macula is positioned at the center. In the initial setting, "Macula" is set for the "Macula" scan mode and "Disc" is set for the "Glaucoma" scan mode. In "Circle scan" for the glaucoma mode, "Disc" is fixed. For the "Fundus Photo" mode for which only color fundus photography is done without tomography, "Center" is initially set.
Selectable fixation position
(9) Distortion Adjust This item is valid only in the following conditions: In the "3D" scan mode for the macula photography and glaucoma, "Scan Size" is 6.0mm×6.0mm, "Scan Resolution" is 512×128, and "Fixation Position" is "Disc". If the patient blinks and his/her fixation position moves during scan, the obtained tomogram is partly deviated or missing. This function automatically detects the deviated or missing data and, after normal scan, scans again at the position of the deviated or missing data. In the initial setting of this instrument, "ON" is set.
