Quick Reference Guide
Pre-test Set-up:
• Push any button to turn the unit on.
• Position the patient so that the test can be conducted level with, and square to, patient’s eyes.
• Choose the appropriate mode using the child/adult button (child mode for 6 yr. and under). Hold button until you hear a double
beep and see the desired icon on the LCD.
• Explain the test procedure to the patient:
• “Now I will check your eyes. You will see a red light in the middle of the blinking green lights.”
• Position yourself at eye-level and square with the face of the patient.
Test Procedure:
• Push the “GO” button on the unit
• Check that the patient is fixated correctly throughout the test.
• Position the unit at the correct distance from the patient:
• When the unit is too far away, you will hear slow, low-pitched beeps.
• • • • • •
• Slowly move closer. At the correct distance (14”), you will hear a steady, low tone. ———
• When the unit is too close, you will hear quick, high-pitched beeps.
••••••
• The crosshair will flash in synch with the tones.
• Look through the peephole and align the crosshair on the pupil of the patient’s right eye. While the unit is acquiring data, you
will hear a very high-pitched chirping sound over the steady low tone. ° ° ° ° °
• If you are not acquiring data (steady tone without acquiring data chirps):
• Scan around the pupil in an outward-moving spiral until chirps begin, then hold this location.
• Ask the patient if they can see the red light.
• When the test of the right eye is complete, you will hear the “tah-dah” sound. (Testing resumes after 1 second, so you do not
need to press any buttons for the left eye test.)
• Without changing position, rotate the unit to the left eye and align the crosshair over the pupil. Repeat test.
• At the end of the test, you will hear the “tah-dah” sound again.
• If the unit has not gathered enough good readings from either eye, you
will hear 5 tones when the test stops. - - - - - You must re-test that eye.
• To stop a test at any time, hold any button until 5 tones sound.
Hints To Insure Good Results & Rapid Test:
• Ambient lighting:
• Don’t perform by uncovered windows
• Dimmed light can help for those with small pupils
• Too dim is difficult for those with dark irises
• Entry angle - straight and level
• Rotate unit to test left eye
• Fixation: “Look at the red light”
• Remind and monitor
• Match patient age and mode
• These are noted on the print out
• Correct distance/Not taking readings (steady tone without chirps):
• Ensure you are level and square with the patient
• Scan the crosshair around the eye in an outward moving spiral until
chirps begin, hold this location
• Ask patient if they can see the red light
• Aim high if testing through glasses
• Make sure the patient’s eyelids are not occluding the pupil
