The TOPCON DRI OCT-1 Model Triton is a non-contact, high-resolution tomographic and bio-microscopic imaging device. It is indicated for in-vivo viewing, axial cross-sectional and three dimensional imaging, and measurement of posterior ocular structures, including the retina, retinal nerve fiber layer, ganglion cell plus inner plexiform layer, ganglion cell complex, macula, optic nerve head, and choroid. The DRI OCT-1 Model Triton is intended for use as a diagnostic device to aid in the detection and management of ocular diseases including, but not limited to, macular holes, cystoid macular edema, diabetic retinopathy, age-related macular degeneration, and glaucoma.

FEATURES

This instrument is a special photography device to observe, photograph and record the image and tomogram of fundus and the image of anterior segment and to present its electronic image for diagnosis. By mounting the anterior segment attachment kit, which is an optional accessory, you can observe, photograph and record the tomogram of anterior segment. After photographing, the images and tomograms of fundus and anterior segment can be recorded in a personal computer where the analysis software is installed. This instrument is classified into two types depending on the combination of the installed functions:

DRI OCT-1 Model Triton:Not equipped with the FA photography function and with the FAF

Manual

• Image Quality value (IQV) is the image quality evaluation standard peculiar to TOPCON. IQV shows the image quality of the tomograms obtained by the DRI OCT-1 Model Triton with a value quantitatively. When you need a tomogram applicable to image analysis or other processing, the IQV must be 40 or

NOTE

higher. If the IQV is 40 or higher, the tomogram has a proper image quality. If the IQV is less than 40, 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.

• If only the images of poor image quality are obtained, contact your dealer or TOPCON listed on the back cover.

Item buttons for setting parameters

(1) Scan Pattern

Scan pattern means the shape or kind to be scanned. It is classified into the following 5 kinds: Line: Scans linearly. 3D: You can scan the range (Scan Size) with the horizontally-set resolution (Scan

Resolution) and display the scanned object as a stereograph.

3D Wide (H): You can scan the range (Scan Size) with the horizontally-set resolution (Scan

Resolution) and display the scanned object as a stereograph.

5 Line Cross: Scans with five lines in each of horizontal and vertical directions at regular inter-

vals crosswise.

Radial: Scans radially with the set radial lines (Radial Scan Count).

(2) Scan Size

"Scan Size" means the length or range to scan.

(3) Scan Resolution

"Scan Resolution" means the data quantity to be read by scanning. In the "Line" and "Radial" scans, it is the data for one line. In the "3D" scan, it is the data for each side of "Length×Width". 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 is increased.

(4) Fundus Photography

You can set whether the fundus photography should be done. This item cannot be set in the instrument without the fundus photography function. (In DRI OCT-1 Model Triton plus, you can select "Color" and "Auto Fluo".)

(5) Fixation Position

Set the fixation position of the patient. There are five selectable items for setting, "Disc" (optic disc), "Center", "Macula", "Wide" and "External" (external fixation target). When "Disc" is set, the optic disc is positioned at the center of the photography screen for the fixation target. 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. When "Wide" is set, the middle position between "Center" and "Macula" is positioned at the center. When "External" is set, the internal fixation target is turned off and the external fixation target is used.

(6) Over Scan Count

"Over Scan Count" means the following function: The data is 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.

DETAILS OF THE SETTING MENU

(7) Myopia mode

In this mode, when taking a tomogram of the fundus of the patient whose eye has excessive myopia or others, the standard interference position is moved to the inner side than the normal position.

(8) Step

This is valid only when the "5 Line Cross" capture icon is selected, and it means the interval of the vertical or horizontal five scan lines. The settable range is 0.15mm, 0.20mm, 0.25mm, 0.30mm and

0.35mm.

(9) Re-scan

If the patient blinks and his/her fixation position moves during the scan, the obtained tomogram is partly deviated or missing. This function automatically detects the deviated or missing data and scans again. This function can be set only for "3D" and "3D Wide".

(10) OCT Live Color

You can set "color display" or "monochrome display" for the live image. In the initial setting of this instrument, "monochrome display" is set for all the live images.

CAUTION

To prevent the instrument from falling and to avoid injury, install the instrument on a level surface.

NOTE

Do not contact the attachment for anterior segment with rubber products during storage. The material may deteriorate.

DAILY CHECKUPS

• Dust is a formidable foe to the instrument. To ensure the production of fine images, care should be taken not to allow fingerprints and/or dirt to get on the objective lens.

• Each time one patient is changed to another, replace the chinrest paper with new one.

• When not in use, be sure to cap the objective lens and cover the instrument with the dust cover.

• Before using the instrument, check if the objective lens is clean. If the objective lens is stained,

clean it following the instructions for "CLEANING THE OBJECTIVE LENS" on page 93.

• When not in use, always turn the OFF ( ).

1 When the external cover and touch display screen become stained, clean them with a dry cloth. 2 If the external cover or the touch display is badly stained, prepare a tepid solution of neutral

detergent. Moisten a cloth and wring it thoroughly. Then, wipe the cover or panel with the cloth.

CLEANING OF THE PARTS WHICH COME INTO CONTACT WITH THE PATIENT

• Before using the instrument, clean the forehead rest unit and chinrest unit. Mix the neutral detergent in tepid water. Moisten a cloth and wring it thoroughly. Then, wipe the forehead rest and chinrest with the cloth.

CLEANING THE TOUCH DISPLAY

• The touch display is a touch panel. Before wiping it, turn off the power switch. If not, the touch display responds to the wiping action to cause a trouble in

operation.

• When the monitor cleaner is dirty, wash and use it. Rinse the monitor cleaner until the cleanser does not remain on it any more. If the cleanser remains on the monitor cleaner, the touch display is not wiped uniformly from time to time.

CLEANING

When the touch display is stained by dust or the like

First, remove dust lightly with a soft brush, etc. Then, wipe the screen lightly with the dry monitor cleaner, which is the accessory.

When the touch display is stained by fingerprint or the like

Wipe the screen lightly with the dry monitor cleaner, which is the accessory. If the fingerprint is not removed well, moisten the monitor cleaner with water a little and then wipe the screen with it.

CLEANING THE OBJECTIVE LENS

• To check if the objective lens is stained, darken the room and illuminate the objective lens with a flashlight, etc. Examine the objective lens diagonally from the front. The lens condition can be seen clearly.

How to wipe the dustproof coated objective lens

The wiping method is different from the conventional coated lens. The resistance against wiping is very low and the lens is smooth.

• Dust and dirt adhered to the surface Blow them off using a blower. Be careful to prevent the blower end from touching the objective lens.

• When the stain is simple such as dust, tears or saliva:

1 Breathe toward the objective lens and wipe it carefully with a piece of lens cleaning paper. 2 If your lens cleaning paper is dirty, replace it with a clean one and repeat 1. 3 Repeat 1 and 2 until no stain is seen on the lens.

• When the stain is persistent:

1 Moisten a lens cleaning paper with reagent ethanol properly. Wipe the objective lens with the

lens cleaning paper by rubbing lightly.

2 If your lens cleaning paper is dirty, replace it with a clean one and repeat 1. 3 Repeat 1 and 2 until no stain is seen on the lens.

• Don't use the following methods because the lens may be damaged.

• Wiping the lens by grasping with fingernails

• Using a lens cleaning paper wound around a hard tool (for example, a metallic tool).

NOTE

• Use a soft lens cleaning paper without fiber.

• For example, BEMCOT (Asahikasei)

• Don't let any strong-alkaline liquid adhere to the objective lens. If such a liquid adheres to the lens, immediately wipe it off.

• If it is difficult to remove a stain from the objective lens, contact your dealer or TOPCON (see the back cover).
