Clinical Evaluation of Patients With X-linked Retinitis Pigmentosa (XLRP)

Males with a clinical diagnosis of X-linked retinitis pigmentosa (XLRP) caused by RPGR-ORF15 mutations will be asked to provide informed consent and will have a single blood or saliva sample obtained for DNA sequence analysis of genes known to cause XLRP, including the RPGR-ORF15 gene. All participants will be informed ...

Phase N/A

Genetics of Charcot Marie Tooth (CMT) - Modifiers of CMT1A New Causes of CMT2

This project is to understand modifier genes and how they influence the severity of disease expression, along with identifying new forms of CMT which have not been genetically determined. Subjects who are eligible will either have CMT type 1A (CMT1A) or an unknown form of CMT. Blood will be drawn ...

Phase N/A

Evaluation of Objective Perimetry Using Chromatic Multifocal Pupillometer

Pupil light reflex (PLR) will be measured by a chromatic multifocal pupillometer in response to short and long wavelength light with small spot stimulus in 76 points of the 30 degree visual field. A computerized infrared video pupillometer will be used to record changes in pupil diameter in response to ...

Phase N/A

Inherited Retinal Degenerative Disease Registry

My Retina Tracker provides three different portals for data entry and review. An entry in My Retina Tracker is initiated by a participant, not a clinician. Using the Participant Portal, the participant establishes a username and password, is guided through on-line informed consent, and can then use an interactive guide ...

Phase N/A

Clinical Implication of Retinitis Pigmentosa Molecular Diagnostic Using High Throughput Sequencing.

The retinitis pigmentosa (RP) are genetic conditions that cause retinal degeneration leading to severe low vision and is the leading cause of consultation in reference centers dedicated to the ophthalmic genetics. These rare diseases are characterized by a triple heterogeneity (clinical, genetic and molecular), which made them unreachable by traditional ...

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 ...

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

New Enrollment Post-Approval Study of the Argus II Retinal Prosthesis System

Safety data will be monitored to ensure continued acceptability of risks to study subjects. The utility (i.e. visual function and functional vision) and reliability of Argus II System will also be evaluated. There is no study hypothesis.

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

Self-confidence Study in Patients With Argus II Artificial Retina

To evaluate whether the use of the Argus II retinal prosthesis improves the confidence and self-esteem of patients with advanced retinopathy pigmentosa
