Dry AMD

Brief summary
In patients with AMD a deterioration of the antioxidant mechanisms of the retina is observed and therefore an increase in the production of free radicals responsible for tissue damage. The Age-Related Eye Disease Study (AREDS) found that the intake of antioxidants reduces the risk of progression of the disease to an advanced stage (choroidal neovascularization or geographic atrophy ) and reduces the loss of visual acuity. In this study the investigators want to analyze the functional retinal changes (mfERG) of the macular region, in patients with dry age-related macular degeneration, after the use for 6 months of an oral supplementation based on Ganoderma lucidum (Reishi), Calendula Officinalis, Lutepure-Marigold ( 5% Lutein and 1% Zeaxanthin) Blueberry, Rutin, Alpha-lipoic acid, Bromelain, NAC, Vtiamine C, B9, B12, D3, Selenium, Zinc and Copper.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of Multifocal electroretinogram (mfERG) in patients with dry age-related macular degeneration after 6 months follow up | Functional retinal changes after 6 months follow up | To evaluate functional retinal changes of the macular region by multifocal electroretinogram in patients with dry age-related macular degeneration after the use for 6 months of an oral supplementation in tablets based on Ganoderma lucidum (Reishi), Calendula Officinalis, Lutepure-Marigold ( 5% Lutein and 1% Zeaxanthin) Blueberry, Rutin, Alpha-lipoic acid, Bromelain, NAC, Vtiamine C, B9, B12, D3, Selenium, Zinc and Copper. The researchers analyzed the average response amplitude densities (RAD: nanoV/ degree 2) between the first negative peak, N1 and the first positive peak, P1 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To evaluate correlation between mfERG changes (functional activity) and morphological retinal changes (CRT: central retinal thickness and VD: vessel density at the superficial and deep capillary plexa) after 6 months follow up | Morpho-functional retinal relationships after 6 months follow up | The researchers evaluated the linear relationships between the mfERG (Response Amplitude Density (RAD nanoV/degree2) and OCT/OCTA values (CRT in micron and vessel density in mm3) by Pearson's Test after administration of a oral supplementation (Macuprev) |
