10. Fluorescein Angiography imaging using optics module Smartscope FA
Optomed Smartscope FA digital ophthalmic camera is intended to capture digital images of the fundus
angiography of the human eye. The device set for fundus angiography imaging consists of:
• Camera handset M5
• Attachable Smartscope FA
• Eye cup for FA
• Cradle for charging and image transfer
Infrared is used for targeting image to the eye fundus and blue light is flashed when image is taken. Pupil
does not respond to the infrared light so examination is convenient for the patient.
Smartscope FA has 9 internal fixation targets for the patient to fixate at while imaging. Below section will
guide how to control the fixation lights.
STEPS FOR RETINAL IMAGING:
1. The examination room should be as dark as possible.
2. Both the patient and the examiner shall be seated while taking the images.
3. When using Smartscope FA optics it is recommend to mount the device on a slit lamp base using Slit
lamp Adapter to achieve good images.
4. Either autofocus or manual focus can be used. Autofocus range is -11 to +3 diopters.
If patient has a refractive error and autofocus is off, focus need to be adjusted:
• Hyperopia: camera is focused to distance by pressing arrow key up. One click of the key is
approximately 2 Diopters.
• Myopia: camera is focused closer by pressing arrow key down. One click of the key is
approximately 2 Diopters.
5. Aiming light is automatically turned on when camera enters live view.
6. The middle fixation target is lit when pressing left soft key and it provides a macula centered image.
To change the fixation target press Left Soft Key and use arrow keys to navigate between the 9 targets
as shown in the graphics in lower left corner of the display. If fixation target is turned off ask patient
to look at a target in a wall 2-3 meters behind the operator.
7. Light is adjusted using left and right arrow key. There are altogether 10 brightness levels. Default value
is 5. Suitable illumination is typically 2 to 8. Changing illumination brightness affects only the blue
capturing flash.
8. Aim help square on the screen guides user when to take image. When retina is not fully in view the
square is red. Once the aim is good and retina fully appears on screen the Square turn’s green
indicating a good moment for capturing the image.
9. Approaching the eye is started from 10 centimeters (4 inch) distance. Pupil is approached until the
reflection from the eye fundus can be seen. The right imaging distance is about 2 cm (0.8 inch). Eye
cup must be compressed approximately halfway down. Aim help square on the display guides to take
image once it turns from red to green.
