  • Confirm the entries by clicking on OK (settings will be saved) or abort by clicking in Cancel (changes will not be saved or applied).

Create new study

If Study oriented has been selected as the Preferred mode of operation, a New study (case) can be created for the selected patient.

  • Select the patient’s last name or patient number in the Patients/visits field and click on Edit. This will bring up the Patient dialog to edit patient data.

Import of patient data

Patient data can be acquired by various methods:

  • By entering new patient data (New button) in the Patient Manager.
  • Import of patient data (Patient import button)

Import of patient data using the DICOM interface

For hospital operation, patient data in DICOM format for patients who are to be examined using the VISUCAM can be imported directly from the DICOM modality worklist of the hospital network server.

To retrieve patient data from the network server into the system Waiting room with the aid of the Network Broker, the Integrated into DICOM network (broker interface) option must be selected in the File – System dialog.

  • Click on the Patient import button in the Patient Manager. The Network Broker dialog will open.
  • On the Patient Based Query tab the number of patients displayed can be limited using the four search fields Patient ID, Patient’s Name, Accession Number and Requested Procedure ID. When entering search criteria the * can be used as a wildcard for a random character. Use the caret symbol ^ to separate first and last names. If a box is left empty, no filter will be set for this element. If all four boxes are left empty, the complete patient list will be displayed.

  • On the right side of the Broad Query tab the search field >Modality can be used to search for patients for a specific device (modality). The examination period can be restricted by using the options on the left side. If these boxes are left empty, the complete patient list will be displayed.
  • On both tabs the search is initiated by pressing Execute and aborted by pressing Cancel. All search fields are reset to their standard values with Reset fields.
  • Enter the desired search criteria in the respective search fields and start the search with Execute.
  • Select the patients to be imported from the displayed patient list.
  • Press Select all to select the full patient list. Press Invert selection to invert the selection and Clear selection to remove the selected entries.
  • Click on OK to confirm the import of the selected data. The patient data will now be imported to the local database of the device.

Import of patient data from a practice management system (EMR system)

Data of patients to be examined with the device can also be imported directly from the patient list in the practice management system.

To retrieve patient data from a practice management system into the system Waiting room with the aid of the SPIF interface, the Integrated into EMR network (SPIF interface) option must be selected in the File – System dialog.

Click on the Patient import button in the Patient Manager.

The patient data will now be imported into the local database of the device.

Import of patient data using the file interface

A continuous automatic request for new data records might be useful for a simple updating of data in the network.

Any text editor can be used for importing patient data. Note the list separation. Data must be entered in the following sequence.

Export of patient data

Patient data can be exported as follows:

  • Export of patient list file
  • Export of patient data and images to pre-configured servers

Export of patient list files

A patient list for export, similar to the above list for importing patient data, can be exported from the program by selecting Export patient list file option from the Tools menu.

  • Click on Export patient list file option in the Tools menu.
  • In the dialog which appears select the storage location for the patient list file (format.pvc.) to be exported.
  • Click on OK.

Preparing image capture

Patient selection

Patients to be examined are selected in the left-hand side of the Patient Manager window. Image capture is not possible until a patient has been selected. Patients are displayed, sorted either alphabetically by last name or by patient number, in the Patients/Visits display field.

  • Select a patient from the Patients display field (or the Waiting Room) by clicking on them.
  • Click on a visit. The captured images will be displayed as thumbnails.
  • By clicking on the Take into… button, the selected patient in transferred to the Waiting room display field.
  • To open the Capture mode window, click on the Capture mode button.

Capturing an image

  • To capture an image of the anterior eye segment, bring it sharply into focus using the knurled knob on the camera head and trigger image capture using the push-button on the joystick.
  • Using the joystick, move the camera head towards the patient until the position indicator switches from AS (anterior segment) to PS (posterior segment).
  • The focusing aid (coincident line pair) and working distance dots will appear together with the fundus.
  • If necessary adapt the brightness with the control knob to clearly show the vessels of the retina.
  • By default, the device is operated in active autofocusing mode meaning that the two lines will coincide automatically. If the pupil is too small it may be necessary to manually focus using the knurled knob.
  • Move the joystick to align the positioning dots such that they are lined up on a horizontal pair of lines in the centre of the image and appear at the edge of the image symmetrically distributed about the centre.
  • Bring the points into focus by moving the joystick forwards and backwards.
  • Image capture is triggered by pressing the push-button on the joystick. The display mode for the live image is set on the Capture mode tab.

Presenting of images

  • Capture mode (Color, R, G, B, FA, AutoFluo, ICGA)
  • FA/ICGA running time for angiography series
  • Patient eye selected (OD/OS)
  • Field angle of displayed image section
  • Print icon, if the image has already been printed
  • Image export icon, if the image has already been exported
  • Copy icon if the image is a (modified) copy of an original image
  • The Comments icon displays existing image comments
  • Single image of a multi-field cycle
  • Stereo symbol (double ring) for stereo image pair
    *The following functions can be carried out using a mouse:
  • Double-click on thumbnail image (The image is opened in the Image viewer)
  • In the Patient Manager, click on a thumbnail with the middle mouse button to view image information.

The image viewer allows you to view, compare, correct and print single or multiple images in a separate window. The images must first be selected in the Patient Manager window.

When viewing images in the Image Viewer window you can choose between 1 Image, 2 Images or All images (split presentation) presentation types.

We recommend using these options as follows:

  • Fast viewing or evaluation of new images, viewing of stereo images (1 image presentation)
  • Comparison of two or more images (2 images presentation)
  • Preparation for printing (4 Image, All Images presentation)
  • Select the required thumbnail images by clicking on them while holding down the CTRL or SHIFT key.
  • Click on the Image viewer button to open the Image viewer window.
  • Click on the appropriate tab to select the split presentation required or all images.
  • If more images have been selected than can be displayed in the selected split presentation, a scroll bar will appear on the right of the dialog with which all the images selected can be accessed.
  • The sequence of images can be changed by drag & drop. To do this, click the left mouse button on an image and drag it to the desired position. The image in that location will be automatically shifted to the original position of the dragged image.

The following functions are available in the Image viewer window.

Printing from Patient Manager mode

You can print single or multiple images using the Print function. The images must first be selected in the Patient Manager window. A maximum of 16 images can be printed per page.

To print multiple images, proceed as follows:

  • Select the thumbnail images to be printed by clicking on them while holding down the CTRL or SHIFT key.

  • Start the printout using Print.
  • Click on Close to switch to Patient Manager without printing.

Image import

The Image import function is used to import one or more images from the hard disk, network drives or removable storage media. Images in JPEG, BMP, TIFF or DICOM formats can be imported:

  • Imported JPG, BMP or TIFF files must be assigned to the relevant patient manually. The program requires the user to confirm that the images are being assigned to the correct patient.
  • Imported DICOM files contain the necessary patient information. The program automatically checks that this patient information is consistent.

DICOM mass import

The DICOM mass import function enables the import of all DICOM images of one directory. It can be used to restore a patient database.

  • Activate the DICOM mass import function from the Tools menu.
  • Select the directory with the DICOM images to be imported from the browser windows which will open now.
  • Confirm your selection by clicking on OK. The import will now start.

Image export

The Image Export function allows one or more selected images to be exported to the hard disk, network drive or removable storage media. Images can be saved in JPEG, BMP, TIFF or DICOM formats.

If the JPEG format is used, a reduction in image quality can be selected to allow file compression in order to reduce the file size. An image quality of less than 70% will, however, result in a loss of image information.

To export selected images, use the following procedure:

  • Highlight the images to be exported
  • Click on the Image export button (This will bring up the Save as dialog)

  • Select the folder or storage medium from the Save drop-down menu.
  • Confirm the suggested file name or edit as required. The suggested file name contains the components selected on the File export tab in the Settings dialog.

File mass export

The File mass export function enables a simplified form of image export for data backup. All images of selected patients can be exported.

  • Click on File mass export in the Tools menu.
  • In the left selection field of the File mass export dialog select the patients whose images shall be exported.
  • Check the desired option in File export settings for the name of the subfolder to which the data is to be exported. If the Subfolder includes name/ID option is checked, the standard file name configured under Settings – File export will be used as a folder name. If the Subfolder includes date option is checked, the current date will be used as a folder name.
  • The options shown under Export selection enable either all images of the selected patient to be exported, or only those images not yet exported.
  • Start the export by clicking on the Export button.
