Regulation of cholesterol metabolism in the retina under experimental conditions associated with glaucoma
2019
Cholesterol is a lipid found in every animal cell and is necessary for its survival. Among its multiple roles in the body, it is a component of cell membranes that is crucial for the maintenance of their structure and fluidity and is thus implicated in the modulation of many signalling pathways. Neurons are especially dependant on cholesterol input since the proper composition of their plasma membrane is required for vesicular exocytosis of neurotransmitters and transduction of the post-synaptic signal. It has been shown that both an excess and a lack of cholesterol is neurotoxic. Moreover, many neurodegenerative diseases, such as Alzheimer’s or Huntington’s disease, have been associated wi…
Observational outcomes in proliferative diabetic retinopathy patients following treatment with ranibizumab, panretinal laser photocoagulation or comb…

Purpose Ranibizumab monotherapy showed stronger effects on area of retinal neovascularization (NV) reduction while offering better visual acuity (VA) results than panretinal laser photocoagulation (PRP) monotherapy during the first 12 months of the PRIDE study. The second year of PRIDE was an observational, non-interventional follow-up, performed to evaluate long-term anatomical and functional outcomes in proliferative diabetic retinopathy (PDR) patients under real-life conditions, prior to the approval of ranibizumab for PDR. Methods Seventy-three PDR patients (28 from the ranibizumab group; 20 from the PRP group; 25 from the combination group) were included in the observational follow-up …
Efficacy and safety of ranibizumab with or without panretinal laser photocoagulation versus laser photocoagulation alone in proliferative diabetic re…

Purpose Panretinal photocoagulation (PRP) is the current standard of care in proliferative diabetic retinopathy (PDR). However, treatment with anti-vascular endothelial growth factor agents might offer better patient outcomes with fewer side-effects. The PRIDE study aimed to assess the efficacy and safety of ranibizumab with or without PRP compared with PRP alone in patients with PDR. Methods A total of 106 PDR patients without diabetic macular oedema were randomized to receive ranibizumab 0.5 mg monotherapy (n = 35), PRP (n = 35) or combined ranibizumab 0.5 mg/PRP (n = 36). The primary objective of this 12-month, multicentre, phase II study was to investigate the change in area of retinal …
