Epithelial Ciliary Proliferation in Retinal Detachment

Claude Boscher (Paris, France) Background: There is some in vitro evidence that the adult ciliary body (CB) might harbor an inactive population of stem/Retinal Progenitor Cells (RPC), or that ciliary epithelial (CE) cells might have the capacity to trans-differentiate, which may result in a balance between neural and epithelial properties. We have reported alterations in the CB and adjacent vitreous in vivo by endoscopic evaluation of...

When the Surgeon’s Eye is Inside the Patient’s Eye

http://www.dailymotion.com/video/xns59p Claude Boscher (Paris, France) Flow control is especially crucial during vitrectomy for retinal detachment because of the risk of iatrogenic retinal tears, due to traction at distance or to direct retinal browsing. Balance between risk and efficiency must be continuously monitored. Endoscopy assisted vitrectomy allows high magnification observation of the vitreous/retinal motion and cutter action....

Endoscopy Assisted Anterior Vitreous Base Peeling

http://www.evrs.eu/medias/2008/congress/Endoscopy-Assisted-Anterior-Vitreous-Base-Peeling.flv Claude Boscher Advantages: High magnification and tangential endoscopic approach of the anterior vitreous base provide the most achieved removal of the anterior vitreous cortex on 360°, independantly of media transparency. High magnification wash out of the ciliary margin might allow stem cells removal with potential therapeutical and prevention...

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 presented...

PVD Status as One Strategical Parameter in PDR

Claude Boscher, Beryl Cathelineau, Jean Francois Gautier, Gérard Cathelineau Purpose: Retinal status regarding ischemia and neovascularization is the usual clinical and paraclinical (fluorescein angiography) decisional parameter in PDR; however PVD status (no PVD, partial PVD, total PVD) carries an essential role in the development and course of the disease. Methods: Retrospective series of 600 patients with DR followed and treated between...

Recurrent Intravitreal Hemorrhage after Endoscopy Assisted Vitrectomy (EAV) for Severe Proliferative Diabetic Retinopathy (PDR)

Claude Boscher, Beryl Cathelineau, P.O. Barale, Raphael S. Amar, Pr Gérard Cathelineau Purpose: Recurrent intravitreal hemorrage after vitrectomy for PDR is reported between 11 and 60% in the literature. Methods: Prospective consecutive non randomized interventional case series of 60 eyes in 47 patients with diabetes 1, and NVC 3 and 4 (DRVS report 3) PDR. Vitrectomy, anterior vitreous base peeling and endophotocoagulation were performed...
