How to add a retinal drawing
You can add retinal drawings to open images.
1. Open the image you want to annotate and then select Annotation menu > Retinal Drawing.
2. Select the retinal drawing type and draw the retinal drawing in the same way as annotations, see
Annotations, retinal drawings and measurements on page 89.
How to mark pathology annotations
Pathology annotations, such as micro aneurysms and exudates, can be marked using the retinal drawing
tools.
1. Open the image you want to annotate and then select Annotation menu > Retinal Drawing.
2. Select the marker from the Retinal Drawing dialog box and click each artifact.
How to count and compare pathology annotations
You can compare pathology annotations marked on two open images for the same patient, for example to
compare a recent image with one from a previous session. Select the second image from the drop-down
list in the Annotation Counts dialog box to display the pathology annotation count in the lower grid.
1. Open the images you want to compare. If you want to count the pathology annotations for a single
image just open one image.
2. Select Annotation menu > Measure > Count Annotations to display the Retinal Drawing dialog box. The artifact
counts for the selected image will be displayed.
3. If comparing pathology annotations, select the second image to be counted and then select the
annotations layers to be included in the count. Images need to be registered correctly when
counting annotations, see Registering image reference points.
4. Optional: You can also print the pathology annotation count information by clicking the Print button.
Note
A pathology annotation will be counted twice if annotated in two annotation layers.
Using measurements
You can add, remove and edit measurements on the displayed image. The measurement information is
stored in an annotation.
Some measurements are not available when the image was captured using a standard optomap® capture
procedure. ISNT Rule Measurements are only available when the image was captured using an optomap® plus
or optomap® fa capture procedure. The relevant tools are made available when the image is opened.
Measurements cannot be edited or deleted after the image has been closed.
Note:
Measurements can be deleted and edited in the same way as standard annotations, see Using
annotations on page 52.
How to measure an area
1. Open the image you want to review.
2. Select Annotation menu > Measure > Area Definition and select the method you want to use to mark the area.
l
Freehand – use the mouse cursor as a pen to draw around the area.
l
Polygon – use the mouse cursor to draw a shape, using straight lines, around the area.
l
Ellipse – use the mouse cursor to draw an ellipse around the area.
3. Select Annotation menu > Measure > Measure Area and mark the area as follows:
l
Freehand – hold down the left mouse button and draw around the area to be measured.
Release the mouse button when you have finished drawing the area.
