OPERATING PROCEDURE: Retroillumination Image Observation
When analysis is complete, the opacity indexes for the center
(COI. H, COI. A) and periphery (POI) and a circle indicating
the 3 mm range in diameter are displayed.
If the pupil of the image to be captured cannot be detected,
“PS+OVER” or “PS-OVER” is displayed. Capture the image again.
When the pupil size is 3 mm or less in diameter, “----” is displayed in the opacity index POI for the
periphery.
Pressing the start button before image capture returns to the Step 1 display.
3
Switch the eye to be measured and perform retroillumination image observation for
the other eye in the same manner.
COI. H
Opacity size within a diameter of 3 mm of
the center (vertical diameter): mm
COI. A
Opacity proportion within a diameter of 3
mm of the center: %
POI
Opacity proportion within the entire
periphery: %
Print

indexes and retroillumination images of the right eye and left eye when both eyes
