Plasma omega 3 polyunsaturated fatty acids and macular pigment optical density in subjects at high risk for age-related macular degeneration: the Lim…
2016
This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.; Purpose: In numerous epidemiological studies, omega 3 polyunsaturated fatty acids (PUFAs) have been associated with a decreased risk of age-related macular degeneration (AMD). Beyond their structural, functional and neuroprotective roles, omega 3 PUFAs may favor the retinal accumulation of lutein and zeaxanthin and thus increase macular pigment optical density (MPOD). We examined the associations of MPOD with plasma omega 3 PUFAs in subjects with at least one parent affected by neovascular AMD. Methods: The Limpia study is a double-blind, placebo controlled, prospective randomize…
Plasmalogens and cell-cell communication between retinal glial cells
2016
This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.; Purpose: Plasmalogens (or ether-lipids) are a particular class of glycerophospholipids characterized by the presence of a vinyl-ether bond at the sn-1 position of the glycerol backbone and by the preferential esterification of polyunsaturated fatty acids (PUFAs) at the sn-2 position. Plasmalogens are found at high concentrations in retinal macroglial cells such as Müller cells and astrocytes. Müller cells and astrocytes are known to communicate by the way of intracellular calcium waves and gap junctions. Connexin 43 is the major protein of these communicating junctions. The aim o…
Ranibizumab in patients with neovascular age-related macular degeneration in real-world clinical settings in France: 1-year data from the LUMINOUS (T…
2016
Purpose : LUMINOUS™ (NCT01318941; initiated March 2011) is the largest, prospective, observational, global study in the field of medical retina. LUMINOUS™ is an ongoing 5-year study that is designed to evaluate the long-term safety, effectiveness, treatment patterns, and health-related quality of life associated with ranibizumab (RBZ) 0.5 mg treatment across all approved indications in 30,000 patients from routine clinical practice. We present the 1-year data from the French patients included in LUMINOUS™. Methods : Overall, 17, 545 adult patients with neovascular age-related macular degeneration (nAMD) were enrolled before March 2014; of these 9125 adult nAMD patients with a potential for …

Impact of a reduction of plasmalogen levels on Muller cell metabolism

Purpose : Retinopathy of Prematurity (ROP) is the leading cause of blindness in premature children resulting from abnormal vascular development. Previous studies have shown that omega-3 polyunsaturated fatty acids (PUFAs) can modulate physiologic and pathologic angiogenesis. Data from our laboratory suggest that plasmalogens, that are phospholipids that concentrate omega-3 PUFAs, are involved in the regulation of post-natal retinal vascular development through the action of a calcium-independent phospholipase A2 (iPLA2) (Saab et al PLoSONE 2014). In the retina, Müller cells are known to play crucial functions in retinal angiogenesis as well as to be rich in plasmalogens and to express phosp…
