Foresee PHP™
Introducing a new standard for the early detection of CNV
The Foresee Preferential Hyperacuity Perimeter (Foresee PHP®) system is indicated as a diagnostic aid for detection and monitoring of the progression of Age-related Macular Degeneration (AMD) including, but not limited to, the detection of Choroidal Neovascularisation (CNV).

Highlights
Long term monitoring of AMD: Enhanced patient report tracking of the visual field changes over time.
Rapid test time: Less than 5 minutes per eye, reducing technician time by up to 80%.
Advanced software: Algorithm that measures relative photoreceptor sensitivity and field location to identify CNV lesions at an earlier stage.
Non invasive and easy patient use: Increases accuracy and compliance.
Automated analysis of test results: Locates and quantifies AMD visual disturbance patterns and provides reliability parameters.
The only device with clinically validated normative data base for early detection of CNV

How the Foresee PHP® Test Works
1. The Foresee PHP® test consists of a series of dot deviation signals (white dots on a black background for maximum contrast) flashed at predefined intervals, across the central 14° of the patient's macular visual field (figure 4).
2. Projection of a dot deviation signal on a retinal lesion can cause the patient to perceive distortion, scotoma, and/or blurring of part of the line.
3. The patient is asked to report any abnormalities in the dot-deviation signal by touching the screen at the location of the abnormality with the stylus. Existing visual field defects can be identified should the dot-deviation signal be positioned on a lesion.
4. During the course of the test, artificial distortions, that imitate distortions similar to those seen by patients with AMD related macular lesions, are flashed. These artificial distortions act as both a quantifying measure and a reliability measure. The patient's responses to these distortions are evaluated to identify AMD lesions and to judge test reliability.
5. The Foresee PHP® system consists of a screen-based application that runs on the Foresee PHP® device. The patient's responses are recorded and analysed by a pre-designed algorithm.
6. Following the analysis, the resulting report indicates whether progression of AMD is suspected or not.
