PHP Home Preferential Hyperacuity Perimeter for the Detection of Choroidal Neovascularization (CNV)

Overview

The primary objective of this study is to assess the ability of the PHP & HPHP to detect newly diagnosed non treated Chorodial neovascularization (CNV) lesion associate with advanced age related Macular Degeneration (AMD) and differentiate them from Early/intermediate/GA AMD
