Incidence, Risk Factors and Outcomes of Submacular Hemorrhage with Loss of Vision in Neovascular Age-Related Macular Degeneration in Daily Clinical P…
2023
To evaluate the proportion, baseline predictors, and outcomes of neovascular age-related macular degeneration (nAMD) patients treated with a high burden of vascular endothelial growth factor (VEGF) inhibitor intravitreal injections (IVT) at two years in routine clinical practice. European retrospective data analysis from a prospectively designed observational outcomes registry: the Fight Retinal Blindness! (FRB!) Project. Treatment-naïve eyes (one eye per patient) initiating VEGF inhibitors IVT from January 2017 to March 2020 with 24 months of follow-up, a minimum of 3 injections, and no gap between visits exceeding 365 days were tracked in the registry. We analyzed three treatment burden (…
Long-term intake of Lacticaseibacillus helveticus enhances bioavailability of omega-3 fatty acids in the mouse retina
2023
Omega-3 (n-3) polyunsaturated fatty acids (PUFAs), particularly docosahexaenoic acid (DHA), are required for the structure and function of the retina. They could also help to prevent or delay the development of retinopathies. Given the accumulating evidence showing the role of gut microbiota in regulating retinal physiology and host lipid metabolism, we evaluated the potential of long-term dietary supplementation with the Gram-positive bacterium Lacticaseibacillus helveticus strain VEL12193 to modulate the retinal n-3 PUFA content. A set of complementary approaches was used to study the impact of such a supplementation on the gut microbiota and host lipid/fatty acid (FA) metabolism. L. helv…
Role of 24-S-hydroxycholesterol in membrane dynamics during retinal gliosis in glaucoma
2017
International audience; Purpose : Glaucoma is a severe and irreversible ocular disease characterized by progressive optic neuropathy with the loss of retinal ganglion cells (RGC). One of the established causes of RGC apoptosis is Müller Glial Cell (MGC) activation, called “retinal gliosis”. MGC are the most numerous glial cells in the retina and one of their roles is to maintain cholesterol homeostasis. A lack or an excess of cholesterol in neurons can cause neuro-degeneration. Cholesterol 24S-hydroxylase (CYP46A1) is present in RGC where it catalyses the formation of 24S-hydroxycholesterol (24S-OHC), and thereby participates to cholesterol elimination. CYP46A1 is overexpressed during glauc…
