Intended Use

The Foresee Home is intended for use in the detection and characterization of central and paracentral metamorphopsia (visual distortion) in patients with age-related macular degeneration, as an aid in monitoring progression of disease factors causing metamorphopsia including but not limited to choroidal neovascularization (CNV). It is intended to be used at home for patients with stable fixation.

Device Story

Foresee Home is an interactive, software-driven perimeter device for home use. It presents linear images to the macular and peri-macular region to quantify metamorphopsia (visual distortion) based on hyperacuity (Vernier acuity). The device detects shifts in photoreceptor position caused by retinal pigment epithelium elevation. Patients perform tests at home; results are transmitted electronically to healthcare professionals. The system does not provide automated interpretation or treatment decisions; it serves as a tool for clinicians to monitor disease progression. The device facilitates remote monitoring, allowing earlier intervention for conditions like CNV. It is intended for patients with stable fixation.

Clinical Evidence

Bench testing and usability studies were performed. A usability study showed 98.5% of users could perform the test independently after training. A correlation study between home-simulated and clinic-supervised testing showed 93.85% agreement. Clinical performance metrics (81.5% positive agreement, 87.7% negative agreement) were derived from the predicate device (K050350) validation against gold standards (color fundus photography and fluorescein angiography).

Technological Characteristics

Interactive software-driven perimeter; utilizes hyperacuity (Vernier acuity) testing principle. Includes a telemedicine module for electronic data transmission. Designed for home environment. No specific material standards or software architecture class provided.

Indications for Use

Indicated for patients with age-related macular degeneration and stable fixation to detect and characterize central and paracentral metamorphopsia as an aid in monitoring disease progression, including choroidal neovascularization.

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.

## DESCRIPTION OF THE DEVICE SUBJECT TO PREMARKET NOTIFICATION

The Foresee Home system is an interactive software driven device that provides a series of linear images to the macular and peri-macular region of the eye. The changes in macular and near macular function can be quantified by the device thus enabling the reader to detect early changes in macular degeneration and associated diseases to allow earlier intervention.

The Foresee Home applies the concept of the static and automated perimeter in the detection of visual field defects. The technology, based on hyperacuity, is used for highly specific quantification of central and paracentral visual fields defects. Hyperacuity (also termed "Vernier acuity") is defined as the ability to perceive a difference in the relative spatial localization of two or more visual stimuli. Hyperacuity threshold may be as low as 3-6 sec of arc and the hyperacuity stimuli are highly resistant to retinal image degradation and thus suitable for assessing retinal function in patients with opaque media as well. Retinal pigment epithelium (RPE) elevation, such as that

which occurs in AMD, causes a shift in the regular position of photoreceptors. It is hypothesized that such a shift causes an object to be perceived at a different location from its true location in space.

The analysis engine of the device tries to define areas in the visual field that are suspected as being related to CNV. Such areas are called CNV related zones. Although these zones are called 'CNV-related,' they simply indicate areas of greater metamorphopsia and can often occur in non-CNV lesions."

Note that the response on this indicator is only indicative of the presence or absence of significant metamorphopsia that may exist in conditions NOT associated with CNV (such as geographic atrophy or drusen).

The Foresee Home is intended to be used in a home environment following training given by a qualified healthcare professional. The user interface and interaction with the device is similar to office Preview PHP. The results of each testing session, the test reports, similar to these generated by the Preview PHP system, will be transmitted electronically directly to the healthcare professional. Test reports will not be displayed on the monitor in the patient's home, but rather will be used by the healthcare professional in the same fashion as it is currently employed with the in-office Preview PHP. Thus, the only difference between the Preview PHP system and the Foresee Home is that the Foresee Home unit is placed in the patient's home environment to facilitate testing and the test report is then transmitted to the healthcare professional.

It should be noted that the Foresee Home is not intended to provide automated interpretation, evaluation, treatment decisions, or to be used as a substitute for professional healthcare judgment.

## INDICATION FOR USE

The Foresee Home is intended for use in the detection and characterization of central and paracentral metamorphopsia (visual distortion) in patients with age-related macular degeneration, as an aid in monitoring progression of disease factors causing metamorphopsia including but not limited to choroidal neovascularization (CNV). It is intended to be used at home for patients with stable fixation.

## TECHNICAL CHARACTERISTICS

The technical characteristics of the Foresee Home are similar to the Preview PHP (KOSO350).

## PERFORMANCE DATA

Since the results of testing of the Foresee Home results are similar to those of the Preview PHP, the performance. i.e., percent positive agreement and percent negative agreement of the Foresee Home, are also similar to the performance of Preview PHP (K050350).

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

The clinical study submitted in K050350 for the Preview PHP was designed to validate that that the minimal percent positive agreement and minimal percent negative agreement are greater than 80%. The study results demonstrated that the percent positive agreement was 81.5% and percent negative agreement was 87.7%. The Preview PHP results were compared to the gold standards, i.e., color fundus photographs and fluorescein angiographics.

This 510K addresses the ability of the system to be used in home environment. The Foresee Home usability study showed that after clinic training, 98.5% of the users were capable of performing the test by themselves.

Comparison between unsupervised test in a home simulated environment and supervised test in the clinic showed correlation of 93.85%, indicating that the test results are similar no matter if the examination was supervised at the clinic or performed without assistance by the users at their home environment.

#### BASIS FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE

The technological characteristics and testing results of the Foresee Home in home use are similar to these of the predicate device, the Preview PHP, cleared under K050350.

The Amsler Grid has similar intended use: to rapidly detect central and paracentral irregularities in the visual field.

Data transfer is accomplished by means of a telemedicine module that is substantially equivalent to the Motiva Monitor Device, cleared under K071564. Additional predicate devices are included and offer similar collection and transmission of health related information from the patient's home to health care professionals; these include the River I telemedicine system (K063609) and the Commander III (K053303).
