PBM Treatment
EXPERIMENTALThe Valeda™ Light Delivery System will deliver 590, 660 and 850 nm wavelengths together.
Sham Treatment
SHAM COMPARATORThe Valeda™ Light Delivery System will deliver non-effective treatment of the 590 and 660 nm wavelengths together.
Interventions
The Valeda Light Delivery System delivers 590, 660 and 850 nm wavelengths of light to the study eye. The Valeda Light Delivery System will treat through the open eyelid with the 590 nm and 850 nm wavelengths together. The 660 nm wavelength will be treated through the closed eyelid.
The sham mode emits an approximate 100x reduction in the highest dose for the 660 nm wavelengths as compared to the treatment mode, producing a slightly duller light. The 850 nm (NIR) wavelength (which is not visible light) is not provided in the sham treatment.
Eligibility Criteria
You may qualify if:
- Male or female at least 50 years of age at Screening visit
- Subjects with ETDRS BCVA letter score of between 50\* and 75\* (Snellen equivalent of 20/100 to 20/32). \*If the subject meets this criterion at the Screening Visit but is outside the letter score by up to two letters at Baseline, the subject may be entered in the study.
- Subjects with a diagnosis of dry AMD as defined by the presence of drusen (regular or reticular pseudodrusen) and/or geographic atrophy (GA) visible on two of the following: color fundus images, OCT and/or Heidelberg FAF
- Able to communicate well with the Investigator and able to understand and comply with the requirements of the study
- Subject is informed of the nature of this study and has provided written informed consent in accordance with institutional, local and national regulatory guidelines
You may not qualify if:
- Current or history of neovascular maculopathy that includes any of the following:
- Choroidal neovascularization (CNV) defined as pathologic angiogenesis originating from the choroidal vasculature that extends through a defect in Bruch's membrane
- Serous and/or hemorrhagic detachment of the neurosensory retina or retinal pigment epithelial (RPE)
- Retinal hard exudates (a secondary phenomenon resulting from chronic intravascular leakage)
- Subretinal and sub-RPE fibrovascular proliferation
- Disciform scar (subretinal fibrosis)
- Presence of center involving GA within the central ETDRS 1 mm diameter at Screening
- Media opacities, including cataracts, which might interfere with visual acuity or imaging in the study eye(s). Subjects should not be entered if there is likelihood that they will require cataract surgery in the study eye in the next 24 months.
- Posterior capsule opacification, which might interfere with visual acuity or imaging in the study eye(s). Subjects should not be entered if there is likelihood that they will require surgery in the study eye in the next 24 months
- Invasive eye surgery (e.g. cataract, capsulotomy) on a qualifying eye within three 3 months prior to Screening
- Ocular disorder or disease that partially or completely obstructs the pupil (e.g. posterior synechia in uveitis)
- Visually significant disease in any ocular structure apart from dry AMD (e.g. diabetic macular edema, glaucoma (using \>2 eye drop medications, uncontrolled IOP and/or central/paracentral visual field loss), glaucoma surgery, active uveitis, active vitreous disease, intraocular tumor, retinal vascular diseases)
- Has a serious medical illness that will prevent the subject from performing study activities (including cardiac, hepatic, renal, respiratory, endocrinologic, neurologic, or hematologic disease) or, in the judgement of the Investigator, is likely to require surgical intervention or hospitalization at any point during the study
- Presence of or history of malignancy within the past 5 years other than non-melanoma skin or squamous cell cancer or cervical carcinoma in-situ
- Is non-ambulatory
- +7 more criteria
