Safety and Tolerability of hRPC in Retinitis Pigmentosa

This is a first-in-human open label phase I/II dose-escalation study in which participants with retinitis pigmentosa will receive a single uni-ocular subretinal implantation of one of three doses of hRPC. Treated eyes will be carefully monitored for any ocular or systemic adverse events for 1 year. Testing will comprise a ...

Phase

Argus II Retinal Prosthesis System Post-Market Surveillance Study

This study is being conducted to monitor the use of Argus II in a larger population than available within pre-market approval studies. Safety data will be monitored to ensure continued acceptability of risks to study participants, and an attempt will be made to include all eligible and willing participants implanted ...

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

Safety and Efficacy Study in Patients With Retinitis Pigmentosa Due to Mutations in PDE6B Gene

Retinitis pigmentosa (RP) is a disease where part of the eye (the retina) is degenerating over time. Patients initially present with night blindness, and later in life experience loss of central vision which leads to blindness. RP is a highly variable disorder with some patients developing symptomatic visual loss in ...

Phase

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

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

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

Studying a Potential Protective Effect of L-Dopa on Retinitis Pigmentosa

Retinitis pigmentosa is a group of progressive hereditary diseases that diffusely affects the functioning of photoreceptors and the pigment epithelium. It may be speculated that a protective effect on the pigment epithelium, as it is supposed for L-Dopa, can slow the progression of the disease or even lead to an, ...

Phase

Cone Rescue in Retinitis Pigmentosa by the Treatment of Lycium Barbarum

Objectives: To study the immediate effect and the persistent effect of Lycium barbarum (LB) treatment on retinal functions, especially the cone function, and retinal structure in patients with retinitis pigmentosa (RP) Design: Randomised controlled double-masked trial Setting: Primary Care clinical trial Participants: 120 RP subjects will be recruited from Ophthalmology ...

A Clinical Trial of Retinal Gene Therapy for X-linked Retinitis Pigmentosa

A clinical trial of AAV-RPGR retinal gene therapy for patients with X-linked retinitis pigmentosa
