3.5.4.2 Tear Film
Depending on whether the sequence has followed a sound pattern or not, the
information displayed in the results screen will be one or the other.
3.5.4.2.1 Results screen without sound pattern
Its appearance is shown in the following figure:
Figure 31. Tear Film result screen without sound pattern
The 40 double-pass images recorded during the sequence (see section
“3.5.3.2
Tear Film
”) are shown. Two numerical values can be found at the top of each of
them. The one on the left represents the moment the image was recorded. The one
on the right represents the calculated OSI value for that image.
Also displayed, at the bottom right of the screen, is a chart representing the evolution
of the OSI over time. An increase in the OSI value implies a degradation of the
double-pass image that could be caused by rupture of the tear film. By selecting a
specific area of the graph with the mouse cursor, you can zoom in on that section.
Zoom in, starting from top left, and zoom out starting from bottom right.
