Description
Humphrey HFA II-i
The Gold Standard in Modern Perimetry
Validated by more than 25 years of research, design and clinical experience, the HFA is the accepted standard of care in glaucoma diagnosis and management. With over 65,000 installed units worldwide, the Humphrey Field Analyzer is the premier automated visual field perimeter.
Advanced Analysis
The HFA is the only perimeter with progression analysis validated in the Early Manifest Glaucoma Trial.1
- Enhanced Guided Progression Analysis (GPA) software identifies statistically significant progression automatically, and presents“at a glance” visual field progression analysis on a single page report.
- Visual Field IndexTM (VFITM) is a simple and intuitive global index to determine percentage of field loss on every visual field.2,3
- Pattern Deviation Plots identify localized field loss, minimizing ocular media effects suchas cataracts.
- STATPAC, the language of perimetry, compares results to proprietary age-normative and glaucoma databases.Early glaucoma detection
• SITA-SWAP software reduces blue-yellow threshold test time to just 4–6 minutes, providing a clinically practical tool for early detection of glaucoma.4,5
Enhanced Exam Reliability
- Patented system automatically tracks and aligns head and eye position.
- Kinetic, Custom and Social Security Disability testing provide a wide range of special purpose testing protocols. Practice and patient friendly.
- DICOM Gateway option supports connectivity in DICOM environments such as FORUM® or the U.S. Veterans Administration Hospitals. (Check for availability.)
- HFA-NET Pro with EasyConnectTM RCT provides plug-n-play connectivity solutions to connect to an office network.
- Touch-screen and menu-driven interface simplifies operation.
- Ergonomic design promotes maximum comfort, access and versatility.
Improved GPA Design
- Presents “at a glance” visual field progression analysis on a single page report.
- Quantifies rate of progression with new global index VFI, optimized for progression analysis.
- Displays rate of vision loss relative to patient age for individualized patient care.
- Projects current rate of progression forward up to 5 years to help assess risk of future vision loss if current trend continues.
- Combines Full Threshold and SITA strategies.
- Automates removal of tests with poor reliability.
- Streamlines clinical interpretation and simplifies patient education.
Improved Workflow
- Connect to your EHR, office network or any device using DICOM connectivity with the FORUM Eye Care Data Management system.
- Provides VFI as a simple and intuitive new global index to determine the percentage of visual field loss on every test.
- Prints to virtually any network printer with HFA-NET Pro and EasyConnect.
- Allows non-IT specialists to set up networking with EasyConnect RCT.
- Improves database performance – with Archive/Retrieve up to 60X faster.
