Helpful Hints
Flash Illumination:
If the photo is too light or too dark, adjust the flash illumination on the fundus camera.
This is done by pressing the Setting Switches (#3 in camera diagram on page 19). Press
the +/- buttons to increase or decrease illumination. For lighter skinned patients or
patients with big pupils, a lower flash illumination is required. For darker skinned
patients or patients with smaller pupils, a higher flash illumination is required.
Dark Shadows:
If there are dark shadows on the picture, the pupil may not be dilated enough. You can:
1. Wait for the patient’s pupil to dilate more (make sure the lights are off in the
room). Ask the patient to wiggle his/her toes – this makes the pupils dilate.
2. Increase the flash illumination (see instructions above).
3. Use the Small Pupil Knob (#12 in camera diagram on page 19) on the fundus
camera.
NOTE: A ring of dots will appear on the monitor while Small Pupil Setting is on.
In the photo there will be a dark ring around the outside of the retina. This is
normal for the small pupil setting.
4. Darken the room (i.e., close the blinds, put black covering over the windows,
shut off all lights, etc.).
5. Dilate patient’s eyes (this may be necessary for older patients). A clinician or
mid-level staff member should follow the Pupil Dilation Protocol located at the
end of this section. It is also on the EyePACS website. Login to
https://www.eyepacs.org, select “Clinicians” under “Resources.” On the
following screen, select “Pupil Dilation Protocol.”
Target Light:
If patient does not see the target light press the Fixation Target Button (#9 in the
camera diagram on page 19). This will make the light flash and will allow the patient to
find it more easily. If the optic nerve is not located in the correct position, press the
Fixation Target Button (#9 in the camera diagram on page 19) and ask the patient to
identify the light and say whether or not it is flashing. If the patient does not see a
flashing light, he/she is not looking in the right area. Tell the patient to look identify the
flashing light and to follow it even if it appears to move outside of the camera.
