Foresee PHP

Age-related macular degeneration (AMD) is a chronic condition that causes central vision loss. It affects millions of Americans. In fact, it is a leading cause of blindness in people 60 and older. The older you are, the greater your chance of being affected.

The Foresee PHP is a test we used to monitor vision distortion caused by AMD.  This technology is very specific in detecting and characterizing the type of visual distortion patient may suffer as well as it helps in monitoring vision changes.

The Foresee PHP uses a patented technology called Preferential Hyperacuity Perimetry (PHP).  Hyperacuity, or Vernier acuity is the ability of the eye to detect very small differences between two or more stimuli or images.

The Foresee PHP is a very beneficial test to patients with AMD because it allows early detection of visual changes, often before noticeable symptoms.
