Checking the quality of captured images

changed to suit the patient’s individual characteristics.

Poor quality image example, see Badly aligned images - examples on the facing page.
Lids, lashes obscuring the image
You may find that lids and lashes cover part of the image, obscuring some areas of the retina. This may
happen if the patient was too far away from the device, or blinked, when the image was captured. Use the
External Eye Image to check the patient alignment, see Checking the Exterior Eye Image.
Lids and lashes may sometimes obscure part of the image. You can reduce this by following your practice
procedures, see Minimizing lids and lashes in images on page 33.
Patient positioning
You can improve the quality of a captured image by properly positioning the patient. There are simple
ways to improve the patient's positioning.
Capturing an image from a well-positioned patient should produce a good quality image, see Good
Quality Image example below.
Note
Sometimes the patient may be misaligned, see Badly aligned images - examples on the facing page.
Good Quality Image example
The following is an example of an optomap® image of a well-positioned eye. This is the type of image you
should be trying to achieve.
If you do not capture an image like this you should check the instructions for capturing an image, see
Capturing images on page 21.
