Perform a test
Testing overview
WARNING Patient injury risk. Dispose of single-use components (for
example, sensor strips) after using them one time.
WARNING Patient injury risk. The eyecup should be cleaned after each
patient.
CAUTION
Do not connect the RETeval-DR device to the docking station
while measuring a patient. This will compromise the quality of recordings
and subject isolation.
Performing a test with the RETeval-DR device includes a series of steps.
1. Prepare the device
2. Prepare the patient
3. Test the right and left eye
4. Remove the sensor strips from each eye
5. View the results
6. Clean patient-contact parts
Ask the patient to relax and to try not to blink. The patient should not talk, smile, or move
during the test. Doing so will increase the test time.
Ensure that there is no hair between the sensor strip and the skin. The sensor strips
must be able to adhere firmly to the skin. If the patient has oily skin, heavy makeup, or
any other condition that causes the sensor strips not to adhere well, clean the patient’s
skin with soap and water or an alcohol wipe. Use alcohol-based products with caution;
alcohol fumes may cause irritation to the eye.

2. Press the joystick to select New Test .
3. Enter patient information as prompted by the device (name or identifier and date of
