| Summary: |
Age-related Macular
Degeneration (AMD) is a major cause of severe visual
loss and legal blindness in people older than 50 years
of age in the Western world. The main reason for severe
visual loss in AMD patients is the development of
choroidal neovascularization (CNV).
PHP is a visual field test which helps monitoring AMD
patients for early detection of visual disturbances
linked to the AMD progression. PHP technology is based
on a visual phenomenon known as hyperacuity. Hyperacuity
is defined as the ability to perceive minute differences
in the relative spatial localization of two or more
stimuli. PHP test appears to differentiate between CNV
and intermediate AMD, and thus may be potentially
beneficial in monitoring intermediate AMD patients for
the development of CNV. |
