Possible Cause or Solution
• HFA3 not Models 850 or 860.
• Vertex Monitoring not turned on.
• Trial lens holder not in up position.
• Gaze Tracking was not initialized at the start of the test.
• Patient moving away from trial lens - reposition patient.
• Vertex Monitoring needs to be reset.
• Turn off Vertex Monitoring.
• HFA3 not Models 840, 850, or 860.
• Gaze Tracking was not initialized.
• Auto pupil turned off.
• Do not move the Liquid Trial Lens when it is being adjusted (icon flashing red).

- Gray scale is the same one used for White-on-White.
- Use Total and Pattern Deviation plots for diagnosis.
• Patient had difficult time recognizing when to respond.
- Re-instruct the patient and repeat the test.
• Size V blind spot check size may be too easy to see at blind spot.
- Consider using Gaze Track only and turn off Blind Spot.
• Blue stimulus color was chosen instead of Blue-Yellow parameter.
- Blue Yellow parameter set to On will give yellow bowl and Blue Size V stimulus.
• Visor not extended during testing procedure.
• Simulation Mode is on.
- Turn Simulation Mode off.
• Trial lens holder in up position for peripheral portion of test.
