Disease Natural History and Biomarkers of SPG3A SPG4A and SPG31

The Neurogenetics Branch (NGB) within the National Institute of Neurological Disorders and Stroke (NINDS) is conducting a study to evaluate patients with hereditary spastic paraplegia types 3A, 4 and 31. The objective of this study is to understand disease progression in these closely related forms of hereditary spastic paraplegia using ...

Phase N/A

Cell Collection to Study Eye Diseases

This study will establish a repository of biospecimens to generate induced pluripotent stem (iPS) cells, which will be used to determine molecular mechanisms for potentially blinding eye diseases including but not limited to: Best Vitelliform Dystrophy (Best Disease); Late-Onset Retinal Degeneration (L-ORD); Age-Related Macular Degeneration (AMD); Leber congenital amaurosis (LCA); ...

Phase N/A

Advancing Understanding of Transportation Options

The investigators will use a multi-site, two-armed randomized controlled trial of older drivers (n=300; 70 years) from clinical settings, and one family member each (n=up to 300), with longitudinal follow-up. Study goals are to test how much the DDA improves outcomes and identify who benefits most from the DDA. Evaluation ...

Phase N/A

Rod and Cone Mediated Function in Retinal Disease

Objective: The objective of this protocol is to investigate local changes in rod and cone photoreceptor function across the retina in healthy volunteers and participants with retinal disease. Study Population: Up to 120 healthy volunteers and 250 participants, age five or older, with retinal disease. Design: This single-center, observational, case-control ...

Phase N/A

Retinitis Pigmentosa Clinical Measures and Repeatability Testing of Potential Outcome Measures

Objective: The objective of this study is to investigate the nature of photoreceptor dysfunction in retinitis pigmentosa (RP) patients using focal static and kinetic psychophysical tests to develop functional outcome measures for the clinical trial study in RP. Correlation of novel spatial functional maps with other functional measures (such as ...

Phase N/A

A Natural History Study of Charcot-Marie-Tooth 4J (CMT4J)

Charcot-Marie-Tooth (CMT) diseases are the most common inherited motor and sensory neuropathies, composed of a group of pathologically and genetically distinct subtypes ranging from slowly to rapidly progressive disease. CMT4J is a rare subtype of CMT caused by mutations in the FIG4 gene. Pediatric-onset disease can often be characterized by ...

Phase N/A

Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford

CoRDS collects contact, sociodemographic and health information about participants. This information is entered into CoRDS and linked to a unique coded identifier. Below are some examples of information requested on the Questionnaire that will be entered into CoRDS: Contact information: Name, Mailing Address, Phone Number, Email Address Sociodemographic information: Date ...

Phase N/A

Retinal Imaging in Patients With Inherited Retinal Degenerations

Retinal degenerations are a group of inherited diseases that result in progressive death of the vision cells, or photoreceptors. Currently there is no treatment or cure for any of these diseases and they ultimately cause blindness in affected patients. We propose to investigate the structure and function of the human ...

Phase N/A

Stem Cell Ophthalmology Treatment Study II

Eyes with loss of vision from retinal or optic nerve conditions generally considered irreversible will be treated with a combination of injections of autologous bone marrow derived stem cells isolated from the bone marrow using standard medical and surgical practices. Retinal conditions may include degenerative, ischemic or physical damage ( ...

Phase N/A

High Resolution Retinal Imaging

Studying the morphology and function of the normal and diseased retina in vivo is needed for advancing the detection, diagnosis, and treatment of retinal disease. This protocol uses an adaptive optics scanning laser ophthalmoscope (AOSLO) to image the normal and diseased retina with individual cellular resolution non-invasively. The primary objective ...
