8.7.3.1 Tips to Optimize OCT Signal
Focus Alignment
There are a number of conditions in which automated function processes could fail, i.e.:
▪ dense media opacities;
▪ eyelashes or eyelids blocking the beam of light;
▪ inability of patients to maintain fixation;
▪ nervous and/or stressed patients with jerky movement;
▪ strong nystagmus.
In cases where adverse conditions occur, it may be necessary to:
▪ optimize the OCT signal manually;
▪ align the tomogram manually;
▪ carry out the exam manually.
To manually compensate patient
refraction errors, scroll over the focus
slider.
Simultaneously observe QI index bar and
scan intensity to receive best results. The
QI index bar displays the signal to noise
ratio.
If the signal strength is low, adjust the focus manually. Additionally, artificial tears may be
used for dilated and dry eye patients.
For patients with severe sight problems,
use a large fixation target.
Focus correction may improve the
saturation of the tomogram.
e
If shadows are displayed on tomogram
edges, check whether the pupil is
centered.
To eliminate shadows, drag the
tomogram into the shadow.
If ghost tomograms are displayed, move
C-Gate position and check if the pupil is
centered.
Proper examination position can be
obtained by scrolling the mouse wheel or
dragging to the desired position.
