Histo Pathological Alterations in Retinal Detachment

Yvette Ducournau (Nantes, France) Presentation will be made of the progressive alterations observed at the level of the photoreceptor and external limiting membrane that appear to be related to the retinal detachment age. These data appear to reinforce observations made on OCT imaging. Immuno-histo chemistry highlights the level of the retinal damage. Examples of persisting alterations after re-attachment by silicone oil will be...

Stem Cells Implantation: Is it the Way of the Future?

http://www.evrs.eu/medias/2008/congress/Stem-Cells-Implantation:-Is-it-the-Way-of-the-Future.flv Yvette Ducournau, Claude Boscher, Didier Ducournau Stem cells have been identified in vitro in the Ciliary Body (« ciliary margin ») of animals and  in post mortem adult human eyes. To our knowledge, culture of Ciliary Body-derived Retinal Progenitors from the adult human eye in vivo has never been published. We have very recently...

ILM Removal: How Does it Work?

Didier Ducournau, Yvette Ducournau 56 ILM from ERM and MH were submitted, in 1988, to a histopathological study with a immunocytochemistry and scanning electron microscopy. A gliosis, GFAP positive, was found on each specimen. A systematic ILM removal was then performed in ERM and in MH since 1989. Over 12 000 cases were performed with a higher medium improvement compared to what is usually reported without ILM removal. In cases of CME, ILM...

Retinal Glial Reaction Patterns and their Relationship to Diabetic CME

Didier Ducournau, Yvette Ducournau Purpose: To compare the gliosis degree of macular astrocytes and Müller cells in different pathological circumstances with and without cystoid macular edema (CME), in order to understand the neuro-pathological reactional mechanisms and thus explain therapeutical results. Methods: Seven globes -3 with CME and 4 without – enucleated for melanoma or endophthalmitis and presenting vascular pathology...
