9 Clinical Trials for Various Conditions
Background: The retina is a thin layer of tissue at the back of the eye. Retinal disease usually reduces a person s mobility because it affects how he or she moves through familiar and unfamiliar environments. Researchers want to see if a virtual reality (VR) tool can provide an easier and more accurate way to assess mobility. Objective: To learn if researchers can track changes in mobility in people with retinal disease using a new VR tool. Eligibility: People aged 5 and older with retinal disease that affects their vision, and healthy volunteers. Design: Participants will have 2-3 clinic visits. Participants will wear goggles or sit in front of a screen while sitting. Using a game controller, they will navigate through 4 obstacle courses presented in VR. Participants will have a medical history exam. They will answer questions about their family history. They will fill out questionnaires about the vision and mobility issues they have in their daily lives. Participants will have a complete eye exam. They will read letters from a chart. Their eye pressure will be measured. Their pupils may be dilated with eye drops. Pictures of their eye will be taken. Lights will be shined in their eyes. Participants will take a visual field test. For this, they will look into a dome and press a button when they see a light. Participants will have an electroretinogram. For this, they will sit in the dark with their eyes patched. Then their eyes will be numbed with eye drops and they will wear contact lenses while watching flashing lights. Participants will have optical coherence tomography. This is a noninvasive procedure. It produces cross-sectional pictures of the retina....
This is a two-step, multicenter, Phase I/II study including an open-label dose-escalation phase (Step 1) and a three-arm, controlled, double-masked, randomized extension phase (Step 2), in subjects with advanced RCD due to a mutation in the RHO, PDE6A, or PDE6B gene.
Background: - People with rod-cone dystrophy (RCD) or enhanced S-cone syndrome (ESCS) have excess fluid under the retina of their eye. This can cause vision loss. The medicine interferon gamma-1b may help people with these diseases. Objectives: - To see if interferon gamma-1b eyedrops are safe for people with RCD or ESCS. To see if the medicine can decrease retina fluid and help prevent vision loss. Eligibility: - People at least 12 years old with RCD or ESCS. Those with ESCS must have two mutations in the NR2E3 gene. Design: * Participants will be screened with medical history, physical exam, eye exam, and blood tests. * Participants will stay at NIH for 3 days and get the first eyedrops. * Participants will give themselves 4 study eyedrops 4 times daily for 2 weeks and keep a diary. * Participants will have 5 outpatient visits over 8 weeks, 2 of which are telephone assessments. They may have: * Repeats of screening tests. * Questionnaires. * Small piece of skin removed. * Eye exams, including eye dilation and tasks on computer screens. * Fluorescein angiography. A dye injected into an arm vein will travel to the blood vessels in the eyes. A camera will take pictures. * Electroretinography. Participants will sit in the dark wearing eyepatches. A small electrode will be taped to the forehead. After 30 minutes, researchers will remove the eyepatches and put in numbing eyedrops and contact lenses. Participants will watch flashing lights. * Electrooculography. Electrodes will be attached outside of the eyes and eye function will be measured in the dark and the light. * Participants will have a follow-up visit after 52 weeks.
The objective of the study is to collect adaptive optics (AO) retinal images from human subjects with outer retinal diseases (diseases of the outer retina including photoreceptor, retinal pigment epithelium (RPE), basement membrane or choroidal pathologies) to develop new diagnostic methods, biomarkers, and clinical endpoints.
Study OpCT-001-101 is a Phase 1/2a first-in-human, multisite, 2-part interventional study to evaluate the safety, tolerability, and the effect on clinical outcomes of OpCT-001 in up to approximately 54 adults with primary photoreceptor (PR) disease. Phase 1 will focus on safety and features a dose-escalation design. Phase 2 is designed to gather additional safety data and assess the effect of OpCT-001 on measures of visual function, functional vision, and anatomic measures of engraftment in different clinical subgroups.
The purpose of the study is to evaluate the safety and efficacy of a single intravitreal injection of virally-carried Multi-Characteristic Opsin (MCO-010).
This study will evaluate the use of autologous bone marrow derived stem cells (BMSC) for the treatment of retinal and optic nerve damage or disease.
The My Retina Tracker® Registry is sponsored by the Foundation Fighting Blindness and is for people affected by one of the rare inherited retinal degenerative diseases studied by the Foundation. It is a patient-initiated registry accessible via a secure on-line portal at www.MyRetinaTracker.org. Affected individuals who register are guided to create a profile that captures their perspective on their retinal disease and its progress; family history; genetic testing results; preventive measures; general health and interest in participation in research studies. The participants may also choose to ask their clinician to add clinical measurements and results at each clinical visit. Participants are urged to update the information regularly to create longitudinal records of their disease, from their own perspective, and their clinical progress. The overall goals of the Registry are: to better understand the diversity within the inherited retinal degenerative diseases; to understand the prevalence of the different diseases and gene variants; to assist in the establishment of genotype-phenotype relationships; to help understand the natural history of the diseases; to help accelerate research and development of clinical trials for treatments; and to provide a tool to investigators that can assist with recruitment for research studies and clinical trials.
The objective of this study is to evaluate the safety and tolerability of escalating doses of a gene therapy called GS030-DP (injected study treatment) administered via a single intravitreal injection and repeated light stimulation using a medical device called GS030-MD (stimulating glasses) in subjects with documented diagnosis of non-syndromic Retinitis Pigmentosa
