How to screen a subject

Before screening

1. Dim the lights, if possible.
2. Close blinds or curtains, if possible.
3. The subject’s back should be positioned to the interfering light source.
4. Avoid direct light into the subject’s eyes from:
• Ambient light sources
• Exterior light
• Incandescent and halogen lights
Note: Florescent light is the best testing environment, if options are limited.

Screening a subject

If the vision screener has a location specified, the name of the location is displayed on the top left of the screen in parentheses. If there is no location specified, and you want a location included in the screening information, on the Home screen touch Tools, and then touch Location to specify the screening location.
Completed exams are saved automatically.
1. Turn on the vision screener. The Home screen appears.
2. Have the subject close his or her eyes for 10 to 15 seconds to encourage dilation.
3. Stand approximately 3 feet (1 meter) from the subject with one foot ahead of the other for stability.
4. Hold the vision screener on an even plane with the subject’s eyes.
The Subject Results screen appears at the end of the screening process.
Note: Do not allow the device storage to become 100% full. For best results, when the device has accumulated 300 records, delete all records from the vision screener. Verify you have successfully exported the records to a USB flash drive before you select Clear All.

Understanding the results

All results viewing options are in the Tools menu under Results.
The device displays a message indicating whether the results are in or out of range. The message is intended to prompt the caregiver to assess whether the subject should be referred to an eye care specialist for further evaluation or simply be monitored at future screenings.
Results that are out-of-range are indicated in red.

5. Touch the age range on the Home screen that matches the age of the subject.
The screening begins immediately. The vision screener emits the sound of chirping birds. This sound is intended to focus the subject’s attention on the device. Touch the Loudspeaker icon to mute the device.
6. Keep the vision screener steady until the screening wheel appears, indicating the capture process is underway.

Connect the vision screener to a printer

The vision screener is capable of connecting and printing to most network-capable Hewlett-Packard printers. The vision screener also contains some generic PCL drivers that can be used with older printers. For more information, see the device Directions for use.
You can connect the vision screener to a USB printer or, if the vision screener is connected to a wireless network, to a wireless network printer.
1. Touch Tools, and then touch Printer. The Available Printers screen appears.
2. Touch Plus. The Add Printer screen appears.
3. Select the printer to add, and then touch Save.
4. If you do not see the printer you want to add, touch Refresh.
5. To verify the printer is installed correctly, touch Print test page.
For more detailed information, see the device Direction for use.

Troubleshooting

Accommodation

Accommodation is the automatic adjustment of the focus of the eye by flattening or thickening of the lens.
Accommodation occurs when the subject fixates on the vision screener. This improves vision for hyperopia (farsighted) subjects.

To reduce the possibility for a subject to accommodate

• Once the subject is seated, have the subject close his or
her eyes for 10 to 15 seconds to encourage dilation.
• Position the vision screener on the same plane with the
subject’s eyes.
• Activate the screening seconds before the subject opens
his or her eyes.
• Ask the subject to open his or her eyes to obtain quick
capture, prior to the subject’s eyes readjusting to the lights.

To encourage dilation

The vision screener yields a “Pupils too small” message if the following occurs:
• The pupils are constricted below 4 mm.
• If the subject has something impeding the vision screener’s
infrared light source, such as blindness in one eye, cataract, media opacity, etc.
First attempt recommendation
• Once the subject is seated, have the subject close his or
her eyes for 10-15 seconds to encourage dilation.
• Position the vision screener on an even axis with the
subject’s eyes.
• Activate the screening seconds before the subject opens
his or her eyes.
• Ask the subject to open his or her eyes, which allows
for a quick capture before the subject’s eyes readjusts to the lights.
Second attempt recommendation
• In addition to the recommendations from the first attempt:
° Have the subject use his or her hands to shield his
or her eyes, or
° Use a book or magazine to shield his or her eyes.

Vision Screener–Quick Reference
Third attempt recommendation
• In addition to the recommendations from the second attempt:
° Have the subject wear non-prescription sunglasses
to shield light, or
° Use sunglasses that wrap to block light from his
or her eyes.
Final recommendation
• Try new, darker environment and repeat the above recommendations.
• Turn the device out of view from the subject and reactivate the screen while rotating the device back to the subject.

Wireless issues

1. On the Home screen, verify the network name and IP address are displayed in the upper-left corner.
2. On the Home screen, verify the wireless icon is gray and there are vertical bars next to it indicating the strength of the connection. If the icon is red, restart the system.
3. If the connection does not automatically reconnect, touch Tools > Network > Security Type and enter the network information again.
For more information on wireless issues, see the device Directions for use.

System freeze

If the vision screener locks up and becomes unresponsive to the touch, perform a hard system reset.
CAUTION: This procedure may cause some data loss (for
example any printer configuration or subject information).
1. Press the Power button.
2. If the Power Off screen appears, touch Confirm to shut down the device.
3. If the Power Off screen does not appear, press and hold the Power button.
4. Wait one minute, and then restart the device.
For complete instructions, warnings and cautions, please consult the Directions for use that shipped with your device.

Printer issues

1. Verify the printer is turned on and has sufficient ink or toner.
2. Print a test page directly from the printer.
3. Verify the printer is on a local network by printing to the printer from a computer on the same network.
4. If all of the above steps have not resolved the issue, restart the vision screener.

System restart

1. Press the Power button and hold until a confirmation screen appears.
