PHP Home Preferential Hyperacuity Perimeter for the Detection of Choroidal Neovascularization (CNV) - Full Text View

Purpose

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

The PHP is a class I FDA approved Device ( K050350 )

Eligibility


Ages Eligible for Study:	50 Years and older (Adult, Senior)
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No
Sampling Method:	Probability Sample

Study Population

At least 200 subjects with intermediate AMD in at least one (1) eye based on medical record review and/or clinical diagnosis and at least 200 subjects with neovascular AMD in at least one (1) eye in all sites.

Criteria

Inclusion Criteria:

Patients with AMD related lesions:

Newly diagnosed (up to 6 months) non-treated CNV patients secondary to AMD in the study eye, or GA patients or Early and Intermediate AMD patients.

Age ³ 50 for AMD patients
VA with habitual correction in study eye 6/60 or better
Mental and physical ability to perform a PHP/HPHP test
Subject able and willing to sign consent form and participate in study
Subject is not participating in another study when conducting the test

Exclusion Criteria:

Evidence of macular disease other than AMD or Glaucoma in the study eye.
- Presence of any significant media opacity that precludes a clear view of the macular area as identified by biomicroscopy, fundus photography, or fluorescein angiography in the study eye
- Any non-macular related ocular surgery performed within 3 months prior to the study in the study eye
- CNV patient inability to tolerate intravenous fluorescein angiography
