Humphrey Field Analyzer – HFA II-i Series

• World standard of care
• All major clinical trials have relied on the Humphrey*
• Connectivity to office network and EMR**
• GPA™: perimetry progression software; allows for full analysis on one page
• GPA minimizes false positives by taking into account test-retest variability of the general population
• VFI™ minimizes the effects of cataracts for the purpose of measuring progression
• STATPAC™ analysis: sophisticated analysis made simple
• SITA algorithm for fast and precise visual field threshold measurements
• Gaze tracking: highly precise, real-time measurements for reliability
• SITA-SWAP provides early detection***
  

* Advanced Glaucoma Intervention Study (AGIS), Collaborative Initial Glaucoma Treatment Study" or CIGTS, Early Manifest Glaucoma Trial or (EMGT), Normal Tension Glaucoma Study (NTGS), and Ocular Hypertension Treatment Study (OHTS).

** Using DICOM, or you can export jpg or pdf files via the USB port to a PC or EMR.

SITA testing strategies available on the HFA II-i:

• SITA Standard: A threshold testing method which collects the same amount of information in half the time as the original Humphrey^® Full Threshold standard algorithm, without compromising test reproducibility.
  
• SITA Fast: A threshold testing method that collects the same amount of information in half the time as FastPac, without compromising test reproducibility.

Monitoring and maintaining patient’s eye position with the Humphrey:

• Gaze tracking is a unique fixation tracking system that records if patient is fixating properly while each stimulus is presented.
• Head tracking ensures proper alignment of the head and eye relative to the trial lens holder.
• Video eye monitoring helps to position the test eye in the center of the trial lens holder and monitor the patient during testing.
• Vertex monitoring uses the distance between two corneal reflexes to determine if the patient has moved too far back from the trial lens. The software will flag the movement and ask the operator to realign the patient or re-initialize the system.

EMR integration with FORUM
Connectivity to an EMR through FORUM delivers significant practice efficiency and offers closed-loop workflow helping to eliminate patient data errors.

For legacy patient records, FORUM offers FORUM ASSIST Match, a quick and simple way to find and merge multiple patient records using a variety of match criteria.

Basic Networking
You can export files via the USB port, or over the network, and save to shared folders on a PC for transferring data to EMRs.

1. Baseline Examinations
   Establish initial visual field status
2. Visual Field Index Value 
   A summary measurement of the patient’s visual field status, expressed as a percent of a normal age-adjusted visual field
3. VFI Rate of Progression Analysis
   Trend analysis of the patient’s overall visual field history1
4. VFI Plot
   Regression analysis of VFI values and 3 to 5 year projection
5. VFI Bar
   A graphical depiction of the patient’s remaining useful vision at the current VFI value along with a 3 to 5 year projection of the VFI regression line if the current trend continues
6. Current Visual Field Summary
   Complete report of current visual field including VFI, MD, PSD, the Progression Analysis Plot and the GPA alert
7. GPA Alert
   A message that indicates whether statistically significant deterioration was noted in consecutive tests.
