Chapter 5 - About capturing an image
Depending on the configuration of your device the following procedure types and options may be
available:
If following an optomap® plus procedure you can select the following:
l
If required, capture an AF image, see How to capture Autofluorescence images on page 27.
l
The Fixation Level controls the brightness of the green ball which helps the patient look in the
correct direction. The Fixation Level can be altered if the patient is having trouble seeing the green
ball. You should select the dimmest level the patient can see to ensure the best possible image.
l
If required, capture a stereo pair, see How to capture Stereo images. If required, capture an eye
steered image using an eye steering direction, see How to do eye steering on page 29.
l
If required, capture a ResMax™ image of the central pole,see How to capture a image. ResMax™
is not available for optomap® fa for central pole procedures.
Single Image Preliminary checks
These preliminary checks should be carried out when following an optomap® or optomap® plus
procedure. It is also used in the first part of the procedure for capturing optomap® fa images.
l
Clean the face pad and head rest before starting this procedure, see Cleaning Instructions.
l
Ensure that the patient understands what will happen during the exam, see Patient instructions.
If following an optomap® fa procedure:
l
The system automatically follows the optomap® fa procedure to capture color/red-free images of
both eyes. You should capture the fellow eye first and then capture the study eye. This leaves the
patient aligned for the study eye on the next step in the optomap® fa procedure.
l
If you need to check the settings for controlling the early-phase of the angiography procedure you
should do this now, before proceeding. The early-phase criteria are set in the Multi-frame Settings
window.
Capturing Stereo Images
Some systems may be configured to capture pairs of Stereo Images. Stereo Images are images of the same eye
where two images are captured a few millimeters apart. The images are identified as Stereo 1 and Stereo 2.
You must capture both Stereo 1 and Stereo 2 images to complete the pair.
Caution
Stereo Images should not be used for diagnostic purposes.
The Stereo 1 and Stereo 2 pairs are displayed as Linked Images in the Review application. optomap®, optomap®
plus and ResMax™ images can be captured as Stereo Images.
When reviewing Stereo Images you need to either:
l
use a stereo viewer (stereograph).
l
focus in front of the images.
l
focus behind the images.
How to capture
1. Prepare to capture an image
l
Check the device has warmed-up and that the device is ready to capture.
l
Clean the relevant parts of the device, see Cleaning before each patient on page 20.
l
Work through the dialog boxes and select the patient, procedure and eye to be imaged.
Some devices are configured to capture optomap® af images. If you want to capture an
optomap® af image you should select the option when selecting the procedure.
l
Lower the chin cup to the lowest height, see About the head rest on page 8.
l
Dim the lighting in the room to achieve maximum natural dilation of the pupils before
attempting to capture an image.
