Survival of Monocytes Collected From Patients With Atrophic AMD in Retinal Pigmented Epithelium Explants

: The blood sample from all groups will be taken on the day of inclusion, in the ophthalmology department. The patient will be cared for by a nurse and then taken to the collection room. A 100 ml sample will be taken (10 tubes of 10 ml). Blood samples will be labeled with the patient's identification number as part of the protocol. They will be transported to the research laboratory in order to be picked up for monocyte extraction. The purification of blood monocytes will be done. In case of excess, the samples will be destroyed at the end of the study.
