Brief Summary
The purpose of this study is to evaluate clinical outcomes of Photobiomodulation treatment on patients with dry Age Related Macular Degeneration (AMD). Photobiomodulation is the use of non thermal, non laser light of specific wavelengths and energy directly on the eye to improve retinal function and delay AMD progression. This is a prospective 2 center phase 2 clinical pilot study with no placebo group.

Outcome Measures
Primary Outcomes (1)
Change in ETDRS Visual Acuity
prior to intervention and 3 monthly intervals to 1 year
Secondary Outcomes (2)
change in contrast sensitivity
prior to intervention and 3 monthly to 1 year
changes in retinal function parameters from Nidek MP1 assessment
prior to intervention and 3 monthly to 1 year
Interventions
Two separate light emitting devices that are already approved for other indications are used. Treatment will consist of 18 treatments lasting approximately two minutes per treatment.
Eligibility Criteria
You may qualify if:
- patients of both genders aged 50 years inclusive and over
- patients must have DRY macular degeneration in the study eye
- best corrected visual acuity between 20/40 and 20/200
- patients must be competent to sign and have signed a consent form before study entry
You may not qualify if:
- visually significant cataracts
- presence of a visually significant posterior capsule if prior cataract has been performed
- any visually significant disease process in any ocular structure that would affect vision unrelated to macular degeneration
- a patient can be enrolled if only one of their eyes meets the criteria
- patients with severe clinically significant medical disease or unstable medical conditions including cardiovascular, hepatic, renal, neurological, endocrine, gastrointestinal, CNS or life threatening disease or current malignancy at the discretion of the investigators
- patients who are non-ambulatory or bed ridden
- female patients who are pregnant or of childbearing potential as the effects of PBM on the developing fetus are unknown
- patients with a history of epilepsy
- patients with a history of alcohol, drug or substance abuse in the past 6 months
- patients deemed uncooperative or non compliant with the requirements of the protocol
