Measurement Values Results Page - PLUSOPTIX S12C Short Manual

3 "Measurement values" results page
The measurement values are shown separately for the right eye (OD) and the left eye (OS):

If the measurement values are outside the measuring range, "HYP" (for hyperopia) or "MYO"
(for myopia) is displayed as the measurement of the spherical equivalent instead of a
quantitative numerical value.
The spherical equivalent is shown instead of the sphere in order to ensure that the referral
criteria can be applied irrespective of the cylinder setting. The spherical equivalent is defined
as "sphere + ½ cylinder".
You can see the gaze map for each eye on the left and right edges of the screen. This
illustrates the lines of vision of the eyes during the measurement. As soon as one eye is
focussed more than 10 degrees from the camera (this relates to the inside of both circles),
the points on the gaze map are shown in red. A measurement is then not possible and it will
be interrupted inconclusively.
The Plusoptix Vision Screener compares the lines of vision of both eyes and calculates the
asymmetry of the lines of vision (ASY). An asymmetry of 0° is equivalent to perfect
symmetry. Asymmetrical lines of vision can be caused by squinting or decentralised fixation.
Attention:
The displayed asymmetry of the line of vision is not equivalent to the squint angle.
Note:
If a child is not looking at the nose of the smiley face during the measurements,
this can cause a termination of the measurement or inaccurate measurement
values of the asymmetry of the line of vision. For this reason, do not use any other
external fixation aids!
