VEGFA variants as prognostic markers for the retinopathy in pseudoxanthoma elasticum.

Pseudoxanthoma elasticum (PXE) is a rare autosomal recessive ectopic mineralization disorder, characterized by skin, eye and cardiovascular symptoms. The most devastating ocular complication is choroidal neovascularization, which is thought to be mediated by vascular endothelial growth factor (VEGF) signaling, a molecule encoded by the VEGFA gene. As early detection and treatment is essential to preserve vision, prioritization of patients at risk is crucial, but impossible because of wide phenotypic variability and a lack of genotype-phenotype correlations for PXE.

Ranibizumab for choroidal neovascularization secondary to pseudoxanthoma elasticum: 4-year results from the PIXEL study in France.

Purpose: To evaluate the long-term effectiveness and safety of ranibizumab 0.5 mg in patients with choroidal neovascularization (CNV) secondary to pseudoxanthoma elasticum (PXE) in a real-world setting.

Methods: A descriptive, observational, multicenter study in a retrospective and prospective cohort was conducted in France that included patients who had received at least one injection of ranibizumab 0.

Progressive outer retinal necrosis and immunosuppressive therapy in myasthenia gravis.

Introduction: Progressive outer retinal necrosis (PORN) is a rare but devastating infectious retinitis associated with varicella zoster virus (VZV) and responsible for severe visual loss.

Case Report: A 59-year-old man treated for generalized myasthenia with oral azathioprine and prednisone presented with severe unilateral necrotizing retinitis. Polymerase chain reaction of the aqueous and vitreous humors was diagnostic for VZV PORN.

Blue light-filtering intraocular lenses and post-operative mood: a pilot clinical study.

The purpose of the study was to determine if implantation of blue-filtering intraocular lenses (IOLs) affects post-operative mood, inducing more depression, compared to patients undergoing implantation with conventional IOLs. The study was conducted at the Angers University Hospital, France. This was a prospective with a lowercase pilot study, including consecutive patients planned to undergo cataract surgery in both eyes within 1 week.
