Age-related Macular Degeneration of Atrophic Type Treated With Umbilical Cord Blood Enriched With Platelet Plasma.

Age-related Macular Degeneration of Atrophic Type Treated With Intravitreal Injection of Umbilical Cord Blood Enriched With Platelet Plasma: Multicenter Study.

The objective of the study will be to evaluate the efficacy of intravitreal injections of Umbilical Cord Blood Platelet-rich Plasma (CB-PRP) in order to reduce or stabilize the atrophic progression in dry Age-related Macular Degeneration (AMD).

Patients will undergo intravitreal injections of CB-PRP (Cord Blood Platelet-rich Plasma) according to three different treatment regimens, and the efficacy and safety of CB-PRP in an in vitro model of lipopolysaccharide (LPS)-induced degeneration in hTERT RPE-1 and ARPE-19 model cell lines derived from retinal pigmented epithelium (RPE) will be evaluated.

The purpose of this study is to evaluate the safety and efficacy of different temporal regimens of intravitreal administration of CB-PRP and the response of photoreceptors in the macular region in dry-AMD. Microanatomical changes in the retina induced by intravitreal CB-PRP therapy and measured by advanced retinal imaging techniques will be evaluated as an important signal of efficacy.
