Alaska Blind Child Discovery
Referral Criteria for PlusOptix S09
Home
The
PlusOptix S09 is an amazing objective vision screening device for programs
for several reasons. It is infrared meaning kids don’t shy away
from a bright visible flash. It can be very quick taking only about 2-3
seconds to acquire multiple radial digital photoscreening images from
which the computer can interpret. It provides useful output for both eyes
including the full estimate of
glasses power (sphere, cylinder and axis), pupil size and estimated
ocular alignment horizontal
and vertical.
Unlike almost all other devices, it allows the user to input, and alter
the referral criteria!
Why is it important and helpful to be able to change the referral criteria?
Because the needs screening program may change for different communities.
For instance, a screening in a Kindergarten close to an eye doctors office
may want to refer all kids who have marginal problems (15%) because the
follow up exam is affordable. On the other hand, a vision screening program
in a rural Alaska village of infants and preschoolers may only wish to
refer those screenings with more severe problems because the follow up
Confirmatory Exam would require a flight,
overnight stay plus rural eye exam costing a family more than $1000.

Hints for entering criteria in PlusOptiX Software under the criteria Tab:
You
have to delete every line of criteria up to the one you're wanting to
change before it "takes".
-Every month has to be included (Ex. 0 to 8, 8 to 72, etc.) because the
software understands it to be "0 to 7 months, 31 days". If you
start the next group at 9 months, then 8 month-olds have no cutoff criteria.
-Pressing "Enter" at the end of each criteria line enters the
data into the software.
