Meibography (Fig. 12)
Remove the cone to use infrared light only. In the
acquisition screen, take a picture of meibomian
glands turning the upper or lower eyelids with a
cotton but or the fingers (be sure that the lid is turned
and not just pulled down).
Move the instrument to get on focus to have a wider
view. Take the picture (with white button on left side,
with the space bar o with the foot pedal) and close
the actual screen with CLOSE.

After taking the picture, select the green button on

To perform the glands analysis, draw with the mouse
the lid area margins and press “>”. The detection of
the loss area is done automatically by the instrument.
Otherwise, it is possible to select semi- automatic or
manual detection. At the end of the procedure will
be shown the image with the lids and glands area
highlighted with red and green color (Fig. 12.1). Now
you can save the measure to return on the exams screen.
