Intended Use

The Guided Progression Analysis for the Humphrey® Field Analyzer II (HFA II) and Humphrey® Field Analyzer II- i series is a software analysis module that is intended for use as a diagnostic device to aid in the detection and management of ocular diseases including, but not limited to, glaucoma. It is also intended to compare change over time and determine if statistically significant change has occurred.

Device Story

GPA is a software module for Humphrey Field Analyzer II/II-i series perimeters; processes visual field test results from up to 14 follow-up tests compared to an established baseline. Identifies progressive visual field loss in glaucoma patients; highlights changes exceeding clinical variability; provides plain-language alerts (e.g., 'Possible Progression'). Calculates Visual Field Index (VFI) as a percentage of remaining useful vision; generates VFI Rate of Progression plots with 3-5 year trend projections. Used by clinicians in eye care settings to monitor disease progression; output informs clinical decision-making regarding glaucoma management and treatment adjustments. Benefits patients by providing objective, longitudinal tracking of visual field status.

Clinical Evidence

Bench testing and clinical literature review. Sponsored study of 363 glaucoma subjects across nine sites quantified perimetric test-retest variability using SITA Standard, SITA Fast, and Full Threshold algorithms. Results established significance levels for change detection. Literature review confirms GPA performance in glaucoma populations and validates the Visual Field Index (VFI) methodology.

Technological Characteristics

Software analysis module for Humphrey Field Analyzer II/II-i series. Utilizes linear regression analysis for VFI trend projection. Implements statistical thresholds based on perimetric test-retest variability. Operates on existing HFA hardware platforms.

Indications for Use

Indicated for practitioners to assist in the detection, measurement, and management of visual field loss progression in patients with ocular diseases, including glaucoma. Aids in assessing change over time, including change from baseline and rate of change.

Regulatory Classification

Identification

A perimeter is an AC-powered or manual device intended to determine the extent of the peripheral visual field of a patient. The device projects light on various points of a curved surface, and the patient indicates whether he or she sees the light.

Predicate Devices

• Humphrey® Field Analyzer II (K954167)
• Cirrus™ HD-OCT with Retinal Nerve Fiber Layer and Macular Normative Databases (K083291)

## INDICATIONS FOR USE

The Carl Zeiss Meditec, Inc. Guided Progression Analysis is a software analysis module for the Humphrey® Field Analyzer II (HFA II) and Humphrey® Field Analyzer II - i series (HFA II - i) that assists practitioners with the detection, measurement, and management of progression of visual field loss. It aids in assessing change over time, including change from baseline and rate of change. It is intended for use as a diagnostic device to aid in the detection and management of ocular diseases including, but not limited to, glaucoma.

# DEVICE DESCRIPTION

The Carl Zeiss Meditec, Inc. Guided Progression Analysis (GPA) is a software package for the Humphrey Field Analyzer II and II - i series that is designed to help practitioners identify progressive visual field loss in glaucoma patients. GPA compares the visual field test results of up to 14 follow-up tests to an established baseline over time and determines if there is statistically significant change. The GPA printout highlights any changes from baseline that represent larger than expected clinical variability, and it provides simple plain-language messages such as "Possible Progression" or "Likely Progression" whenever changes show consistent and statistically significant loss. The GPA printout also presents the Visual Field Index (VFI), a global index which reports a measure of the patient's remaining useful vision in the form of a percentage, as well as the VFI Rate of Progression plot which provides a trend analysis of the patient's overall visual field history and indicates a 3-5 year projection of the VFI regression line if the current trend continued.

### SUBSTANTIAL EQUIVALENCE

The Guided Progression Analysis for the Humphrey® Field Analyzer II (HFA II) and Humphrey Field Analyzer II- i series is substantially equivalent to the Humphrey® Field Analyzer II and Guided Progression Analysis for the Cirrus HD-OCT with Retinal Nerve Fiber Layer (RNFL) and Macular Normative Databases. The

{2}------------------------------------------------

indications for use for the Guided Progression Analysis for the Humphrey® Field Analyzer II and Humphrey® Field Analyzer II- i series are similar to the indications for the predicate devices cited in this application. A technological comparison demonstrates that the Guided Progression Analysis for the Humphrey® Field Analyzer II (HFA II) and Humphrey® Field Analyzer II- i series is functionally equivalent to the predicate devices.

Evaluation of published literature on Guided Progression Analysis for the Humphrey® Field Analyzer II and Humphrey® Field Analyzer II- i series supports the indications for use statement, and demonstrates that the device is substantially equivalent to the predicate devices and does not raise new questions regarding safety and effectiveness.

#### CLINICAL EVALUATION

Clinical data on GPA has been collected by various researchers and is reported in the clinical literature.12 A review of the clinical literature that discusses the relevant studies related to the development of GPA for analysis of visual field progression has been included in this Premarket Notification. GPA incorporated the visual field progression metrics successfully used in the Early Manifest Glaucoma Trial (EMGT), 34 in which pattern deviation maps were used to identify statistically significant visual field progression.

Carl Zeiss Meditec. Inc. sponsored a study to quantify perimetric test-retest variability in glaucoma subjects having a wide range of visual field loss. A total of 363 qualified glaucoma subjects were enrolled across a worldwide nine-site study. Each subject was tested four times within one month. The results of this study, which used the three threshold testing algorithms available on the Humphrey Field Analyzer (SITA Standard, SITA Fast, and Full Threshold), established the limits for change at different significance levels based on test-retest variability in glaucomatous visual fields. The results allow HFA GPA to indicate when the change for a given patient at a given test location exceeds the test-retest variability for the region.

{3}------------------------------------------------

GPA was further refined to include the visual field index (VFI) described by Bengtsson and Heijl.5 This index utilizes data from the pattern deviation probability maps and is incorporated into the new VFI graphical analysis in the GPA software. Linear regression analysis was used to determine the rate of change in VFI. For a visual field series with sufficient follow-up data, the linear regression line is extended into the future to aid the clinician in estimating a patient's future visual status, should previously observed progression rates continue into the future.

### SUMMARY

As described in this 510(k) Summary, all testing deemed necessary was conducted on the Guided Progression Analysis for the Humphrey® Field Analyzer II (HFA II) and Humphrey® Field Analyzer II- i series to ensure that the device is substantially equivalent to the predicate devices, and safe and effective when used in accordance with its Instructions for Use.
