The PreView PHP Preferential Hyperacuity Perimeter provides an unsurpassed level of sensitivity and specificity in detecting recent onset Choroidal Neovascularization (CNV) and differentiating it from the intermediate (dry) state of AMD. The visual field analyzer monitors macular function by measuring relative photoreceptor field location and utilizing the phenomenon of hyperacuity, the ability to detect the misalignment of an object’s location relative to the other objects in space. By combining the patient interactive software with the innovative algorithm, PHP technology can identify CNV lesions when they are small and when visual symptoms are still unnoticed. Early detection remains the vital precursor to preserving vision and maximizing treatment outcomes. The earlier the detection, the earlier the treatment, and better the visual outcome. Zeiss Preview PHP Technology: The Foresee PHP Technology is based on the well-studied phenomenon of hyperacuity. Hyperacuity, also known as Vernier acuity, is the ability to detect misalignment of an object’s location relative to other objects in space. This ability to detect misalignments is in the magnitude of 3-6 seconds of arc, which is 10 times better than the resolution ability in the fovea (around 30-60 seconds of arc). Hyperacuity is unaffected by a patient’s age and is highly resistant to retinal image degradation, and is thus suitable for assessing retinal function in patients with cataracts as well.
