Cause:
The rings are too far to the right.
Correction:
Using the joystick, move the slit lamp to
the right.
Cause:
The reading in this position is considerably
higher than real ocular pressure.
Correction:
Using the slit lamp height adjustment
mechanism, lower the slit lamp until the two
fluorescein semi circles are equal in size.
The measurement pressure will then be
reduced.
