CArotenoid in hypoChOlesterolemia
Hypobetalipoproteinemias (HBL) represent a heterogeneous group of disorders characterized by reduced plasma levels of plasmatic lipids (mainly triglycerides, total cholesterol (TC), LDL-cholesterol (LDL-C), and apolipoprotein B (apoB)) below the 5th percentile of the general population adjusted for age, gender. HBL may be attributed to inherited disorders caused by mutations in …
Fertility and the Microbiome
With this study, the investigators want to investigate the microbiome and human papilloma virus (HPV) status of couples with subfertility. The investigators want to gain information about association of female and male microbiome and its impact on fertility. HPV prevalence is high, and its impact on fertility has not been …
Longitudinal Prospective Natural History Study of Retinopathy in Zellweger Spectrum Disorder
The goal of this observational study is to define the course of the retinal degeneration in a ZSD patient cohort. The objective of this study is to gather information so the investigators can: define the course of the retinal degeneration in a ZSD patient cohort with retinal degeneration define what …
Mechanisms of Inherited Retinal Dystrophies Using Whole Genome Sequencing and in Vitro and in Vivo Models
Inherited retinal dystrophies (IRDs), a large group of heterogeneous and rare disorders, may result in irreversible bilateral visual loss and blindness. Characterizing the genetic bases of IRDs will help to understand the pathogenesis underlying the development of retinal damage. Despite the advances in molecular identification of genes causing disease, unsolved …
Rod and Cone Mediated Function in Retinal Disease
Background Retinal diseases cause the loss of rod and cone photoreceptors. Symptoms include vision loss and night blindness. Researchers want to learn about rod and cone function in healthy people and people with retinal disease. They want to know if how well a person sees in the dark can test …
Clinical and Genetic Studies of X-Linked Juvenile Retinoschisis
This study will explore the causes and eye problems of X-linked juvenile retinoschisis (XLRS), an inherited disease that causes vision loss primarily in young males. The vision loss, which worsens over time, is a result of schisis, or splitting, of the layers of the retina (tissue that lines the back …
Glaucoma, Visual Field Loss, and Their Association With Life Space in Older Adults
Mobility refers to a person's purposeful movement through the environment from one place to another and can be conceptualized as a continuum from bed bound (immobility) on one extreme to making excursions to distant locations on the other extreme. Primary open-angle glaucoma (POAG) is a chronic, progressive optic neuropathy that …
AI Screening for Diabetic Retinopathy
The increasing prevalence of diabetes mellitus represents a major health problem, especially since around 40% of diabetic patients develop diabetic retinopathy, which severely impairs vision and can lead to blindness. This development could be prevented by annual check-ups and timely referral for treatment. However, there are major differences in the …
Lyon Sarcoid Uveitis Cohort
Sarcoidosis is a systemic disease with unknown etiology. Chronicity of the disease is observed in 1/3 of cases. Five percent of the affected patients are expected to die due to pulmonary worsening. After pulmonary complications, ocular complications are one of the most frequent complications. In hospital setting 2 to 15% …
Genotype-Phenotype Study of Patients With Plaquenil -Induced Retinal Toxicity, With Evaluation of the ABCA4 Gene
Background Plaquenil (hydroxychloroquine) is an anti-inflammatory drug that is used to treat some autoimmune diseases such as lupus and rheumatoid arthritis. This drug can damage the retina by causing a condition called plaquenil-induced retinal toxicity, which may lead to vision loss. However, most people taking plaquenil do not develop this …
