Study of Photobiomodulation Effect on Electroretinogram Outcomes in Dry Age-Related Macular Degeneration

Study Overview
=================
Brief Summary
-----------------
To evaluate the ability of Photobiomodulation (PBM) treatment using the Valeda® Light Delivery System to improve Electroretinogram (ERG) outcomes in subjects with dry Age-related Macular Degeneration (AMD).

Detailed Description
-----------------
This study is an open label, prospective pilot study to evaluate retinal function after PBM treatment in eyes with dry AMD using ERG. The target enrollment is 15 subjects in up to two sites in the US. All subjects will receive PBM Treatment. Subjects will receive three PBM treatments per week for three weeks for a total of nine sessions over 3 weeks. The primary analysis will examine multi-focal ERG function changes from baseline to Month 1. Secondary analyses will examine multi-focal ERG function change from baseline to Month 3 and 6. Other endpoints will include other functions of ERG, ETDRS Visual Acuity, Contrast Sensitivity, Perimetry, Color Vision test and the Amsler grid test.
